The products are GreenUp Batten. The products have the same electrical and mechanical construction but
different CCTs; length & driver.
For details please refer to appendix 3.
After review, the model BN108C LED28 CW L1200 was selected to be tested.
In order to consider the worst case, the product should be tested at 200mm.
The sample of BN108C LED28 CW L1200 was tested at 200mm from the light source. CCT of the spectral
irradiance was found at 6877 K.
Amendment 1 report:
The original Test report Ref. No. 3141630, dated 2013-10-25 was replaced, include the following additions
and changes, which were considered technical modifications:
1. Add new models. Those models have the same mechanical and electrical construction as the original
types, except different power.
2. Add new LED drivers.
Finally, additional test performed on model BN108C LED36 CW L1200 MB.
The tested samples were considered as GLS product which was tested at illuminance of 500 lx, but not at a
distance less than 200 mm.
In order to consider the worst case, the product should be tested at 200mm.
The sample of BN108C LED36 CW L1200 MB was tested at 200mm from the light source. CCT of the
spectral irradiance was found at 6955 K.

4 EXPOSURE LIMITS P
4.1 General P
The exposure limits in this standard is not less than P
0,01 ms and not more than any 8-hour period and
should be used as guides in the control of exposure
Detailed spectral data of a light source are generally P
required only if the luminance of the source exceeds see clause 4.3
104 cd.m-2
4.3 Hazard exposure limits P
4.3.1 Actinic UV hazard exposure limit for the skin and eye P
The exposure limit for effective radiant exposure is P
30 J.m-2 within any 8-hour period
To protect against injury of the eye or skin from P
ultraviolet radiation exposure produced by a
broadband source, the effective integrated spectral
irradiance , ES, of the light source shall not exceed
the levels defined by:
P
IEC 62471
Clause Requirement + Test Result – Remark Verdict
P
for t > 104 s
4.3.4 Retinal blue light hazard exposure limit - small source N/A
Thus the spectral irradiance at the eye Eλ, weighted N/A
against the blue-light hazard function B(λ) shall not see table 4.2
exceed the levels defined by:
N/A
for t ≤ 100 s
N/A
for t > 100 s
4.3.6 Retinal thermal hazard exposure limit – weak visual stimulus N/A
For an infrared heat lamp or any near-infrared N/A
source where a weak visual stimulus is inadequate
to activate the aversion response, the near infrared
(780 nm to 1400 nm) radiance, LIR, as viewed by the
eye for exposure times greater than 10 s shall be
limited to:
N/A
t > 10 s

6 LAMP CLASSIFICATION P
For the purposes of this standard it was decided that see table 6.1 P
the values shall be reported as follows:
– for lamps intended for general lighting service, N/A
the hazard values shall be reported as either
irradiance or radiance values at a distance which
produces an illuminance of 500 lux, but not at a
distance less than 200 mm
– for all other light sources, including pulsed lamp N/A
sources, the hazard values shall be reported at a
distance of 200 mm
