:ELECTRICAL & PHOTOMETRICAL TEST •
THE LED TUBE IS TESTED WITH GONIOPHOTOMETER
:ELECTRICAL TEST RESULT •

: PHOTOMETRY & COLORIMETRIC TEST RESULT •

:INTENSITY & BEAM ANGEL TEST RESULT •
THE LED TUBE IS TESTED WITH GONIOPHOTOMETER
BEAM ANGLE AND INTENSITY ARE SHOWN IN BELOW

:TEMPERATURE CYCLING TEST RESULT •
ACCORDING TO ISIRI 14878-2-2 SAMPLE IS PLACED IN A TEST CHAMBER IN WHITCH THE TEMPERATURE IS VARIED FROM -10ºC TO +40ºC OVER A 4 HOUR PERIOD AND FOR A TEST DURATION OF 250 PERIODS (1000HR) 4HR PERIOD CONSISTS OF 1 HR HOLDING AT EACH EXTREME TEMPERATURE AND 1 HR TRANSFER TIME BETWEEN THE EXTREME TEMPERATURES.THE LED TUBE IS SWITCHED ON AT TEST VOLTAGE FOR 34 MIN AND OFF FOR 34 MIN.AT THE END OF THE TEST LED TUBE OPERATE AND HAVE A LUMINOUS FLUX WHICH STAYES WUTH IN THE CLIMED LUMEN MAINTENANCE CODE FOR A PERIOD OF AT LEAST 15MIN AND SHOW NO PHYSICAL EFFECTS OF TEMPERATURE CYCLING SUCH AS CROCKES OR DELAMINATING OF THE LABLE

:SWITCHING TEST RESULT •
AT TEST VOLTAGE THE LED TUBE SWITCHED ON AND OFF FOR 30 S EACH. THE CYCLING REPEATED FOR A NUMBER EQUAL TO HALF THE  RATED LIFE IN HOURS

:Tc MEASUREMENT TEST •
LED TUBES SUPPLIED WITH A RATE  INPUT VOLTAGE AND TEMPERATURE IS MEASURED IN DIFFERENT  PARTS OF LED TUBES
THE MAXIMUM MEASURED WAS 40ºC,THAT IS LESS THAN NOMINAL Tc(45ºC)

:OPERATING TEMPERATURE RANGE TEST •
LED TUBES SUPPLIED WITH 211V(92%) INPUT VOLTAGE AND PLACED IN THE CHAMPER WITH -20ºC FOR 3 HR & WITH 244V(106%) INPUT VOLTAGE AND PLACED IN THE CHAMPER WITH +40ºC FOR 3 HR. THERE WAS NO FAULT IN LUMINAIRE S OPERATION AFTER TEST AND THE LIGHT WAS STILL ON

:LUMEN MAINTANENCE TEST •
ACCORDING TO ISIRI 14878-2-2 SAMPLES IS TESTED
THE TEST RESULT IS IN FOLLOWING TABLE

:SAFETY TEST •
ACCORDING TO ISIRI 14878-1&14878-2-2 SAMPLES IS TESTED
THE TEST RESULT IS IN FOLLOWING TABLE
