Standardization, is there need for standards?
The introduction of LEDs into the lighting market has and is making manufacturers and users rethink their lighting needs, test methods and the application of their existing equipment. The rethinking is helped along its way due to the world-wide energy shortage and in particular here in South Africa.
The goals of standardization can be to help with independence of single suppliers (commoditization), compatibility, interoperability, safety, repeatability or quality.
Standards ensure desirable characteristics of products and services such as quality, environmental friendliness, safety, reliability, efficiency and interchangeability and at an economical cost.
Standards for products are broadly divided into two categories namely that of Safety and Performance.
Safety - Safety standards deal with the requirements that will ensure that the products are safe and will not cause harm to the user or the user’s building when used as recommended .
Safety standards offer the tests and test methods to verify that the products are compliant. These safety standards may cover a wide range of products.
Performance - Performance standards deal with the way that the product performs under a test situation. However as quote from
Wikipedia, “The existence of a published standard does not necessarily imply that it is useful or correct. Just because an item is stamped with a standard number does not, by itself, indicate that the item is fit for any particular use. The people who use the item or service (engineers, trade unions, etc.) or specify it
(building codes, government, industry, etc.) have the responsibility to consider the available standards, specify the correct one, enforce compliance, and use the item correctly.
Validation of suitability is necessary
.”
The IEC has published some Standards and two Public
Available Specifications (PAS). The need for the PAS documents is because these have not been accepted as full Standards but have information that is very useful.
These documents suggest that the following quality criteria should be considered when evaluating LED manufacturer’s claims: a) Rated input power b) Rated luminous flux c) LED luminaire efficacy d) Luminous intensity distribution e) Photometric code or the values of the next four measurements f) Correlated Colour Temperature (CCT) g) Rated Colour Rendering Index (CRI) h) Rated chromaticity co-ordinate values both initial and maintained i) Lumen maintenance code j) Rated life (in h) of the LED module and the associated rated lumen maintenance (Lx) k) Failure fraction (Fy), corresponding to the rated life of the LED module in the luminaire l) Ambient temperature (tq) for a luminaire

Existing IEC LED lamp standards could be used.
Mass of LED lamp is high and the lamp holders should be checked .
1550 grams and 800 g
These have the same challenges as the T5 retrofit and the SANS/IEC 60598 should be amended to include the
G13 lamp cap but there is an IEC draft for LED tubular lamps and this is recommended to be used.
The IEC LED draft offers a better solution as it looks at
LEDs and their test systems.
Test facilities may need to be arranged and hence if this is used as a guide or ARP and later become a VC
1 Scope
This International Standard specifies the safety and interchangeability requirements, and the exchange operation together with the test methods and conditions required to show compliance of double-capped LED lamps with caps G5 and G13, intended for replacing fluorescent lamps with the same caps, having:
– a rated power up to 60 W;
– a rated voltage of up to 250 V;
Such LED lamps are designed for replacement without requiring any modification of the luminaire.
The existing luminaires into which the double-capped LED lamps are fitted, can be operated with electromagnetic or electronic control gear.
The requirements of this standard relate only to type testing.
Recommendations for whole product testing or batch testing are given in
Annex A.
5.3.2 Graphical instruction (IEC Draft)
This clause can be used instead of 5.3.3. The steps of applying the product to an existing luminaire shall be as given in Figure 8.
Switch off – remove - replace - connect - switch on

Note no safety circuit shown – SA will require a safety fuse this is in the text of IEC draft

Use the T5 retrofit guide lines as the min basis
Labels three off positions in retrofit
Circuit diagrams shown with changes
Luminaire tested with lamps especially retrofit
LED replacement lamps not recommended for emergency luminaires as a refit but recommend new luminaires are used here.
Zone classified luminaires must be retested with the LED lamps and certificates provided.
All luminaires tested to have photometric data available .
Used the amended SANS/IEC 60598 safety and call for SANS 475 testing for performance data.
Phase this is but issue a working guide so that
Users can specify correctly and manufacturers can compete on an equal basis.
Street light standard is the most urgent followed by high bay luminaires for stores.
All LEDs must state the light output initial value and the value at 1000 hours, 2000 hours and 15000 hours.
The LED survival must be 2% failure before 1000 hours 5 % at 2000 hours and not more than 50% AT
15000 hours. L70F50 ≥ 15000 h=max 50%lamps having lumen maintenance below 70% after 15000 hours and
L85F05 ≥ 1000h = h=max 5%lamps having lumen maintenance below 85% after 1000 hours
CRI greater than 80

Batch testing is required.
Electrical – power and power factor?
This is a quick proposal of ideas but South Africa requires these Standards or guidance so that the local industry can establish themselves, importers can bring in safe and efficient LEDs and products, inter-changeability can be achieved with reliable service for users
Users can specify products fairly and get competitive prices.
Stock holding can be limited
