This study examines the three TCVN standards and recommends improvements to prevent loopholes and accommodate new technologies. It identifies MEPS levels in neighbouring countries for these products and recommends MEPS levels appropriate for Vietnam.It is strongly recommended that consultation with relevant stakeholders in Vietnam be undertaken (i.e. with technical persons familiar with the Vietnamese lighting market) before reaching final conclusions regarding these standards.Tubular Fluorescent LampsEfficacy RequirementsFluorescent lamps generate light by exciting a phosphor coating on the inside of the lamp tube. Two categories of phosphor are typically used:Halophosphate, resulting in lamp efficacy of approximately 50-75 lm/W.Triphosphor, resulting in lamp efficacy of approximately 75-100 lm/W. In recent years, the global fluorescent lamp market has changed such that triphosphor T8 and triphosphor T5 lamps now command a reasonable market share. Triphosphor lamps are however significantly more expensive than halophosphate lamps, due to the cost and scarcity of the phosphors used in their production. Around the world, there is a wide range of MEPS efficacy requirements for tubular fluorescent lamps. Many developed economies have MEPS efficacy requirements of 80+ lm/W which only triphosphor lamps can meet. Information was discovered for a number of Vietnam’s neighbours which require MEPS for tubular fluorescent lamps: Thailand, China and the Philippines. Countries with no MEPS (or for which no MEPS information could be readily found) include Indonesia and Malaysia. REF _Ref240363040 \h Figure 1 graphs the efficacy requirements for low colour temperature lamps (<4400K) for neighbouring countries and for Vietnam. REF _Ref240612062 \h Figure 2 graphs the same for high colour temperature lamps (≥4400K). Note that the China3 requirement is effectively the Chinese MEPS. Note also that the Philippines has a separate MEPS requirement for halophosphate and triphosphor lamps.Figure SEQ Figure \* ARABIC 1: Efficacy requirements for low colour temperature lampsFigure SEQ Figure \* ARABIC 2: Efficacy requirements for high colour temperature lampsFrom observation of each of the above two figures we can make a general conclusion that the efficacy requirements can be divided into two discrete categories: Those that will require triphosphor lamps (or possibly very high quality halophosphate lamps):ThailandPhilippines triphosphorVietnam High, which is (roughly speaking) positioned in the middle of these three “triphosphor requirements”.Those that will require halophosphate lamps:China3Philippines halophosphate Vietnam MEPS, which is (roughly speaking) positioned in the middle of these three “halophosphate requirements”. Note however that the China3 line (effectively Chinese MEPS) appears very low for 5000-6500K lamps.Data from the Vietnamese MEPS registration system (6 products registered) revealed that registered lamps had efficacies of between 56 and 65 lm/W. With the above observations in mind, there are several options for Vietnam, and these are discussed below:The Vietnam High efficacy requirement is well positioned relative to neighbouring countries. Thus it is not likely to benefit from changes to the current position, unless Vietnam has an appetite to change this requirement for other reasons, e.g. to “best practice”. This could involve harmonising with say Japan which has an 85 lm/W requirement for all tubular fluorescent lamps, or with Australia which has a stepped requirement from 66 to 85 lm/W depending on lamp power.The Vietnam MEPS efficacy requirement could be changed as follows:No change. If Vietnam has an appetite to slightly increase MEPS, the requirement could be harmonised with say the Philippines halophosphate requirement, which is slightly higher than Vietnam. This would still allow halophosphate lamps to be sold (i.e. no significant cost increase) but would require these lamps to be slightly more efficient. Note however that, for tubular fluorescent lamps, an increase in lamp efficacy results in more light output, not less power (as is typically the case with CFLs and incandescent lamps). That is, 4-foot lamps remain at 36W but emit slightly more light. This can however mean that less lamps are required per room (“de-lamping”).If Vietnam has an appetite to significantly increase MEPS, the MEPS requirement could be changed such that only triphosphor lamps can be sold, for example by changing Vietnam MEPS to be equivalent to the Vietnam High requirement or similar. Again, 36W lamps remain at 36W but they emit significantly more light, which can result in significant “de-lamping”.Removal of Loopholes and AmbiguitiesThe Standard TCVN 8249 (2009) Tubular Fluorescent Lamps - Energy Efficiency, has been reviewed in order to remove loopholes and ambiguities. REF _Ref240518840 \w \h Appendix A contains suggested revisions to the standard.Other IssuesThe following sections respond to other issues raised by VSQI.ScopeVSQI have requested examination of whether the current lamp scope of 14W to 40W is appropriate, particularly with respect to neighbouring countries. The current scope is described as follows:Tubular fluorescent lamps with the capacity from 14W to 40W.This scope will capture lamps of nominal length 2’ to 4’ (550mm to 1200mm lamps). The current Vietnamese energy efficiency requirements are described in various categories, as per the following table (Table 1 of TCVN 8249) which is taken directly from the existing standard:Capacity WEnergy efficiency lm/wColor temperature Tc <4 400KColor temperature Tc ≥4 400KMinimumHighMinimumHighFrom 14 to 2058725570Over 20 to 4060785875The scope of Vietnam and neighbouring countries energy efficiency requirements for tubular fluorescent lamps are as follows:Vietnam:14W – 40W (2’ to 4’ lamps)China: 14W – 65W (2’ to 5’ lamps)Philippines: 10W – 65W (2’ to 5’ lamps)Australia: 550mm – 1500mm (2’ to 5’ lamps).Thailand: 16W to 80W (2’ to 6’ lamps).Note that most of these countries’ lamp scopes are expressed as lamp power, with the exception of Australia, whose scope is expressed as lamp length in mm. It is however useful, for this study, to discuss lamps in terms of their nominal length in feet (‘) which helps us to more clearly understand exactly which types of lamps are being discussed.With the exception of Thailand, Vietnam’s neighbouring countries all have a scope of 2’ to 5’ lamps. Vietnam may wish to include 5’ lamps in the scope of their MEPS, and this would require the addition of a new row to the current Table 1 of TCVN 8249, e.g. for lamps “Over 40W to 65W”. However this need will also be affected by Vietnam’s preference for changes to the current lamp efficacy requirements (discussed in section REF _Ref241988190 \r \h 2.1), and particularly if they choose to harmonise with a neighbouring country’s requirements. For example, harmonisation with The Philippines’ requirements would suggest that Vietnam should adopt The Philippines’ requirements for 5’ lamps.Other RequirementsVSQI have requested an examination of the need to include requirements for other lamp characteristics within MEPS, and the practice of neighbouring countries with respect to this issue. So far as we are able to ascertain (noting that some difficulties with language translation were encountered) the requirements for neighbouring countries are listed in REF _Ref241899803 \h Table 1.Table SEQ Table \* ARABIC 1: Requirements for Lamp Characteristics in Vietnam and neighbouring countriesCountryMin EfficacyMin Lumen MaintenanceMin Lamp LifeMin CRI (Ra)Colour Temperature (Colour Coordinates)VietnamYesMin 80% after 2000 hrs8000 hrsNoNoChinaYesNo*NoNo≤5 SDCM from target valuePhilippinesYesMin 92% after 2000 hrs10000 hrs (halophosphate)15000 hrs (triphosphor)70 (halophosphate)80 (triphosphor)NoAustraliaYesMin ~87% after 5000 hrsNo79NoThailandYesMin ~90% after 5000 hrsNo80No*mentioned in the MEPS standard, but seems only to require that lamps shall perform as claimed by the manufacturer, i.e. not required to meet a minimum absolute limit.Again, it may be worthwhile for Vietnam to harmonise requirements with The Philippines. In addition, the Chinese requirement for colour temperature is also considered appropriate – this states that the colour coordinates must lie within a maximum distance from the target colour coordinates. Note that the tests for CRI (Ra) and colour coordinates are simple and are typically conducted at the same time as efficacy testing.Lumen maintenance testing does require significant time and cost to test. However, given that many other countries require a minimum value for lumen maintenance, Vietnam may wish to leave a lumen maintenance requirement in their standard for the time being, but then choose at a later date whether or not to undertake check testing of this requirement, i.e. depending on available Government resources and timeframes. Fast Testing MethodVSQI have requested examination of the appropriateness of the “fast testing” method offered in clause 5.3 of TCVN 8249, which states that an on/off cycle of 0.5/4.5 minutes is allowable during life testing. This represents a duty cycle of 10%, which would mean that life testing to 2,000 (operational) hours would actually take 20,000 hours which is more than 2 years. Note that this is likely to be a typographical or translational error – the on and off values appear to have been swapped. The intended on/off values are likely to be 4.5/0.5 which represents a duty cycle of 90%.The cycle of 4.5 minutes on (then 0.5 minutes off) is a much faster switching rate than the test method in IEC 60081 which requires an on/off cycle of 165/15 minutes (a duty cycle of 92%). Faster switching will tend to reduce the life of fluorescent lamps. Almost all IEC member countries rely on the test methods in IEC 60081. As the (we believe intended) duty cycle of the current TCVN standard (90%) is similar to the duty cycle required in IEC 60081 (92%) there is no perceived advantage to allowing the “fast testing” method, and the faster switching will serve to disadvantage lamps tested in this manner. Thus it is recommended that this option be removed from the standard.Tubular Fluorescent BallastsTerminologyUnderstanding of Terminology in Vietnamese StandardsThe Vietnamese ballast efficiency requirements in Table 1 of TCVN 7897 and Table 1 of TCVN 8248 are described in terms of “Ballast Energy Efficiency Ratio” which we have shortened to BEERVietnam. There does not appear to be a clear definition for this ratio in the Vietnamese standards, thus we have assumed that its definition appears in clause 1.2.1 of TCVN 7541-2 which states:Ballast Efficacy Factor = Ballast Factor / Ballast Input PowerThat is, we have assumed that the “Ballast Energy Efficiency Ratio” (BEERVietnam) is the same term as “Ballast Efficacy Factor”. Thus:BEERVietnam = Ballast Factor / Ballast Input PowerWe have also assumed that “Ballast Factor” is equivalent to “Ballast Lumen Factor” as is used in European / IEC standards and regulations. This assumption is supported by clause 1.2.15 of TCVN 7541-2.Understanding of Terminology in European Regulations The European Regulation for Ballasts (245/2009 as amended by 347/2010) describes ballast MEPS in terms of “Ballast Efficiency” which is defined as follows (we have shortened to BEEU):BEEU = Lamp Power / Ballast Input PowerConversion of Vietnamese Terminology to European TerminologyIt is useful to convert the Vietnamese requirements into the European metric, in order to compare with various other countries, for example China and Australia, which use similar terminology and calculations to Europe. Combining the common term between the Vietnamese and European equations (Ballast Input Power) we get:Lamp Power / BEEU = Ballast Factor / BEERVietnamRearranging to make BEEU the subject, this becomes:BEEU = Lamp Power x BEERVietnam / Ballast FactorThis equation is used to convert the Vietnamese requirements into the European metric.Note that BEERVietnam uses Ballast Factor as a percentage (as defined by clause 1.2.15 of TCVN 7541-2) and thus needs to be divided by 100 when converting to the European metric.Energy Efficiency RequirementsThe conversion methodology outlined in the previous section allows us to convert the Vietnamese requirements into the European metric Ballast Efficiency (BEEU). This is useful because BEEU is the basis for the European and Chinese ballast requirements, and is also the basis for the Energy Efficiency Index (EEI) classification system for ballast energy efficiency. The Australian ballast requirements are based on the EEI. The EEI classifications are as follows (in order of decreasing efficiency):A2 BAT (best available technology): electronic ballasts.A2: electronic ballasts.A3: electronic ballasts.B1: magnetic ballasts.B2: magnetic ballasts.C: magnetic ballasts. This classification does not appear in the European Regulation but does appear in Australian MEPS standard AS/NZS 4783.2.The EEI classifications are reproduced in REF _Ref241024503 \w \h Appendix B and are graphed in REF _Ref240961012 \h Figure 3 along with the (converted) Vietnamese requirements. Note that the Vietnamese conversion contains the following assumptions:For magnetic ballasts, a Ballast Factor (Ballast Lumen Factor) of 0.95 has been assumed (as is used in the European and Australian standards). For electronic ballasts this is assumed to be 1.0.For electronic ballasts, the “high frequency” rated lamp power has been used, and some of these have been interpolated from adjacent values, where not available from the European regulation. Note that the EEI classifications are actually discrete values, but have been drawn in REF _Ref240961012 \h Figure 3 as continuous lines, for ease of viewing and understanding.Figure SEQ Figure \* ARABIC 3: Ballast Efficiency (BEEU) – EEI classifications and (converted) existing Vietnamese requirementsFrom REF _Ref240961012 \h Figure 3 we can see that the existing Vietnamese requirements for ballast roughly approximate to:Electronic high: A2 BAT / A2.Electronic MEPS: A3.Magnetic high: B2 / C.Magnetic MEPS: less than C.These have been listed in REF _Ref241112656 \h Table 2 alongside requirements in neighbouring countries. A proposed set of levels for Vietnam has also been proposed in the table and is discussed below.Table SEQ Table \* ARABIC 2: Ballast requirements in Vietnam and neighbouring countriesCountryMagnetic MEPSMagnetic HighElectronic MEPSElectronic HighVietnam – proposedB2A2 BATA3A2 BATVietnam – existing< C (approximately)B2 / C (approximately)A3 (approximately)A2 BAT / A2 (approximately)ChinaB2A2 BATA3A2 BATThailand(*estimated from translation)B1*-A3A2 BATAustraliaB2-B2-IndonesiaUnclear if regulations currently exist - awaiting further detailMalaysiaUnclear if regulations currently exist - awaiting further detailPhilippinesCurrently no regulationsIn REF _Ref241112656 \h Table 1 a set of levels for Vietnam has been proposed (first row of table). The proposed levels assume that Vietnam has an appetite to slightly increase the requirements for ballasts, and the proposed levels would align Vietnam with China. Also, the Vietnamese magnetic and electronic “high” levels would be combined (= A2 BAT). There is no need to have a “high” category for each. The “high” category should be technology neutral and represent the “best available” regardless of the technology employed (magnetic / electronic). This approach is also employed by China.Vietnam may also wish to consider include mandatory requirements for EEI labelling of ballasts, as is the case in Europe and Australia. This would mean that all ballasts are required to be labelled with their EEI classification, as well as meeting MEPS. An example is given in REF _Ref241113732 \h Figure 4 below – see the labelling on the ballast “EEI=B2”.Figure SEQ Figure \* ARABIC 4: Example of ballast EEI labellingIf Vietnam wish to adopt the recommendations from this section, the standards TCVN 8248 and TCVN 7897 would need some modifications in order to incorporate the EEI classification system. The standards would effectively mirror the European system (see REF _Ref241024503 \w \h Appendix B).Incorporation of New TechnologiesIn order to include newer lamp types such as T5, the EEI ballast classification system (as is used by China) could be adopted. The table of values (for all lamps including T5) is reproduced in REF _Ref241024503 \w \h Appendix B.The MEPS and “high” levels could then be chosen as required. Again, the standards TCVN 8248 and TCVN 7897 would require some modifications in order to incorporate the EEI classification system, but this would align them with Europe and China.If Vietnam do not wish to adopt the EEI classification system, the existing Vietnamese standards could be amended in order to include values for T5 lamps in Table 1 of each standard. The values would be reverse-engineered from the EEI system, in the same manner as the existing Vietnamese values were converted into the European metric (see section REF _Ref241114139 \w \h 3.1).Removal of Loopholes and AmbiguitiesThe following ballast standards have been reviewed in order to remove loopholes and ambiguities. TCVN 8248 - Electromagnetic ballasts for fluorescent lamps - Energy efficiencyTCVN 7897 - Electronic ballasts for fluorescent lamps - Energy efficiency.The suggested revisions to both standards are shown below with additions in blue text and deletions crossed out as follows:1. ApplicationThe standard is applied to electromagnetic / electronic ballasts for double-capped fluorescent tubes (T5, T8 and T12) with the capacity rated power from 18W to 40W intended for general purpose illumination, which are connected to a 220V mains supply.5. Testing MethodAt least one unit of the ballast model shall be tested. More than one unit may be tested if requested by the ballast supplier - in this case the arithmetic mean of the results shall be used to determine compliance with this standard. TVCN 8249 Tubular Fluorescent Lamps StandardThis appendix contains suggestions for revisions to TVCN 8249 in order to remove ambiguities.Red text in this appendix denotes explanatory notes – this text is not for inclusion in the standard itself.Blue text denotes suggestions for additions to the standard. Deletions are shown as crossed out text.Struck-out text denotes suggestions for deletions from the standard.Application:The following changes will better specify the scope of the standard and will also ensure that compact fluorescent and circular fluorescent lamps are not captured by the standard:The standard is applied to double-capped tubular fluorescent lamps intended for general purpose illumination (hereby called fluorescent lamps) with the capacity rated power from 14W to 40W for use with both 50Hz and high frequency ballasts connected to a 220V mains supply.This clause might also benefit from stating some exclusions - the following are based on the Australian MEPS standard (AS/NZS 4782.2):This Standard does not apply to lamps that are clearly not intended for general illumination, specifically:(a) lamps with a dominant colour or with an output that is predominantly outside the visible spectrum;(b) lamps for colour matching and that have a colour rendering index greater than 90 and a colour appearance approximating to a point on the black body locus;(c) lamps that are specifically for use in an industrial or agricultural process;(d) lamps for medical applications; or(e) lamps that have been given written exemption by the relevant regulatory authority on the grounds that they are for a specific purpose other than general illumination and are clearly distinguishable from lamps for general illumination.References:The following documents are needed for the standard application. The standard application is stated in the document published with the year mentioned. If the publishment year is not mentioned, the standards are applied in accordance with the latest documents, including amendment.TCVN 7541-2 : 2005, high-efficiency lighting equipment – Part 2 : Method to measure energy efficiency.TCVN 5175 : 2006 (IEC 61195 : 1999), Linear fluorescent tube- Safety requirements.TCVN 7670 : 2007 (IEC 60081 : 2003,Amd 2: 2003, Amd3 : 2005) Linear fluorescent tube – feature requirements.Terminology and definitionThe terminology and definition mentioned in TCVN 7541-2 : 2005 together with the following terminology are used for this standard.3.1 Fluorescent lamp’s initial lighting efficiency efficacyThe ratio between the lamp’s measured initial luminous flux and actual capacity the lamp’s measured power, when tested in the under standard test conditions. Units: lumens/Watt. The initial efficacy is measured on a new lamp after 100 hours of operation. It is normal to “age” lamps for 100 hours before testing.3.2 Fluorescent lamp’s energy efficiencyUnsure of the purpose of this clause – suggest deleting this clause as it may be confused with the previous clause. Moved the words (slightly modified) to clause 4.3.The initial lighting efficiency of fluorescent lamp is specified in the standard testing conditions.Technical requirements4.1 Safety requirementFluorescent lamp must meet the safety requirements mentioned in TCVN 5175: 2006 (IEC 61195: 1999).4.2 Feature requirementFluorescent lamp must meet the feature requirements mentioned in TCVN 7670: 2007 (IEC 60081: 2003, Amd 2: 2003, Amd 3: 2005).The actual capacity measured luminous flux must not be under less than:15% 85% of announced capacity rated luminous flux, for the lamp with capacity rated power up to 20W.10% 90% of announced capacity rated luminous flux, for the lamp with capacity rated power over 20W.Have assumed that the first use of “capacity” is referring to luminous flux.Note that IEC 60081 (clause 1.5.6) allows lamps to measure 92% of their rated luminous flux, whereas the Vietnamese standard allows 85-90%. 4.3 Energy efficiencyThe energy efficiency of the fluorescent lamp is specified as the lamp’s initial efficacy, when tested under standard test conditions.Fluorescent lamp’s energy efficiency is set in two levels: minimum energy efficiency and high energy efficiency level mentioned in Table A1.Table A1: Fluorescent lamp’s energy efficiency CapacityWEnergy efficiencyIm/WColour temperature Tic <4400KColour temperature Tic ≥ 4400KMinimumHighMinimumHighFrom 14 to 2058725570Over 20 to 40607858753.1 Luminous flux remaining ratioAfter 2,000-hour operation, the luminous flux of fluorescent lamp must not be less than 80% of the initial luminous flux.Van: In the standards for lamps, there are requirements of lifetime, lumen maintenance. Testing time for these requirements is 3 month (2000h) and 8 month (6000h) accordingly. I wonder whether these requirements should include or not in the revised version. Steve: it’s a long test, so up to Vietnam as to whether or not to require these tests.3.2 Operation life Suppliers must inform the life of the fluorescent lamp, but its life mustn’t be under 8,000 hours.3.3 Mercury contentThe maximum quantity of mercury present in a tubular fluorescent lamp model shall not exceed 15 mg. 5. Testing methodAt least one unit of the lamp model shall be tested. More than one unit may be tested if requested by the lamp supplier - in this case the arithmetic mean of the results shall be used to determine compliance with this standard. In the case of life testing, at least 20 units shall be tested, and the median result shall be used to determine compliance.5.1 Specifying the energy efficiencyThe fluorescent lamp’s initial luminous flux and capacity are measured in accordance with TCVN 7541-2 :2005; after that the energy efficiency is specified.5.1.1 Specifying color coordinate and color temperatureColor coordinate and color temperature must be measured in accordance with TCVN 7670: 2007 (IEC 60081 :2003).5.1.2 Specifying color index ( Ra)Color rendering index of fluorescent lamp must be measured in accordance with TCVN 7670: 2007 (IEC 60081 :2003)5.2 Measuring luminous flux remaining ratioLuminous flux remaining ratio of fluorescent lamp must be measured in accordance with TCVN 7541-2 : 2005.5.3 Specifying the life circleThe life of fluorescent lamp is tested and specified in accordance with TCVN 7670 : 2007 (IEC 60081 : 2003).The fast testing method can be used ( on-off circle method) to test the life of fluorescent lamp. The on-off circle is carried out as follows:On : 0,5 min;Off : 4,5 min.The method of on-off circle is continuously carried out until there are half of the lamps are broken. Each on-off circle is carried out for one hour.
