Some basic info:
91 3-5mm LED bulbs, 49 White, 42 Blue, placed in a look-alike T8 fluorescent tube
Worldwide voltage, regulated PSU @ 24V
Total power consumption @ 5W
Simple (outdated) non-regulated LED circuit 7 LEDs in a group with a 180ohm resistor
LEDs rated for ~30,000 hours
First light:
Came without a PSU. Returned it for another one.
Second light:
Complete package. Worked well for 3 weeks @ 12 hours a day till one of the group of 7LEDS went dead.
Third light:
Brand new, it was obviously brighter compared to my 2nd light. I wasn't sure whether it was because of the fault in the 2nd light but time will tell.
Two months into usage of the lights.
I am absolutely certain that the light output is decreasing. The third light is no longer as bright as before, now it is just dim. Needless to say for the second light, dimmer.
To summarises:
Unreliable; Not bright at all; Expensive for what it is
Seriously, just stick with fluorescent lights till LEDs have their reliability proved.
There is no way this LED light will achieve 30,000 rated hours at the rate it is getting dim. Actually, LED lights have a rating which states how long they will sustain the bright before decreasing in output. The last time I checked, most LEDs are rated 3000hours only.
Most fluorescent lights at rated for 10,000 hours and they have a relatively constant light output.
