Dimmable SMD LED Tube Light with Low Lumens Depreciation

LongTech T8 tube light, with the special product diameter 26-30mm, cannot seeing the inside LED and light is much more soft and smoothly. This is another successful breakthrough from LongTech and showing our R&D ability.
 

LongTech LED tube light (Model LT-T8-20w, 1.2M) has completed 6000hrs lumens depreciation testing in the first level National Laboratory, beginning from Oct.2009 till Jul 2010. Report shows that light decay is around 7% at 6000hrs.

The test standard is adopted GB/T10682-2002 Double-capped fluorescent lamps--Performance Specifications, taking every thousand hours as testing points. Results are:
 

a. In the first 1000hrs, there is no obvious lumens depreciation.
 

b. At 2000hrs, lumens depreciation rate is 1.51%, and lumens maintenance is 98.49%.
 

c.  At 6000hrs, lumens depreciation is 7.60%

The results taken from the actual test are extrapolated to provide an estimated degradation figure beyond 6000hrs.
 

Predicated data after 6000hrs: the data shows that lumens depreciation is 29.06% at 30,000hrs, namely lumens maintenance is 70.94%, which can meet the standard of Energy Star to LED indoor lights

Features of LED tube light:

· Universal end cap, directly replace fluorescent lamp

· Use high quality and efficiency LED, low power consumption & no pollution

· Long life time, various color temperature for options
 

Application of LED tube light:

House and home, office, school and commercial lighting
