I bought mine 2 years ago and its still working ok. Most likely, will get some replacement bulbs this year. Its great, I am using 2 behind the display. Colour temperature that I measured using my spectrophotometer was 6500K +/- 200. Also more importantly the actual white point measured was very close to 0.3127, 0.33. That's important. I tried using a normal Philips energy savings lite that was rated at 6500K but I measured something like 8000K. And the white point measurement was way off.
LED can get 6500K, need to match the CIE color bin carefully as you mention near 0.3217/0.33 point for all these LEDs, and assemble the same bin LEDs in the strip.. already did for a customer to install 8pcs of 12inch strips behind a plasma... all powered by a cheapo 12V adaptor.. Current regulation (important for longevity of White LEDs) done by the IC built in the strip (different from those cheapo resistor controlled strips)This post has been edited by ar188: Apr 17 2010, 02:39 PM
