I bought a new set of Luxeons from "acme corp" (rather not reveal this company yet) - and although I am happy with the rest, the most expensive, $30 Blue LXHL-LB5C shows as white. On my test rig, at very dim current levels (100-200 mA) it seems like it might have the slightest teal color - maybe - but higher than that and all the way up to the rated 700 mA it is white as white cane be.
At this price - how could they sell a blue LED that's white?
I checked the numbering on the back, and it seems to be the advertised unit:
R5WB 0000058 4202LXHLLB5C
However, the lettering is much thicker than the lettering on the Star III, and the backing is shiny aluminum. Also the lettering is all thew way left and the left digits are even slightly clipped. The III lettering is centered exactly. On the Star III's the backing is brushed aluminum. So I am a bit suspiscious - however it seems difficult to re-letter these, and more effort than it is worth. But to compare, here is one of the III's :
T3J6 0001954 2605LXHLLM3C LUXEON
Seems odd that the V does not have the word "LUXEON" below the numbers, but the III's are actually newer than the V's.
They also sell a "Royal Blue" Star V, and perhaps that is the real blue version. But the color chart shows that wavelength as being very close to their Blue wavelength. I wonder if this somehow got switched. I do have a 1-watt Blue Luxeon Star/O LED and it is as blue as blue can be !!!
