This is a small 3mm white LED. The catalog says it has 1000mcd of brightness, and I think this one actually comes close to living
up to that figure. The color is a fairly even white, resembling a warmish cool-white fluorescent light. When pointed at a white surface,
the wide 45 degree beam illuminates it quite evenly, with only a slight bluish ring about halfway through the circumference of the LED's
I found that these make excellent backlights for analog meters (the kind that use a moving needle indicator). Two
of them were permanently installed in my motorized wheelchair, one on each side of its power meter. They were chosen specifically
because the meter uses different colors on its face, and the white LEDs allow me to see these colors at night which I could not do with
regular colored LEDs.
Examining the LED like I did the other white one above showed the die covered with the phosphor; but I can see the metal surface
of the die cup and the gold wirebonds poking out of the top of the die. This LED also appears far, far brighter than the Hosfelt 25-367
when viewed off-axis; this is probably because the phosphor layer is much thinner and doesn't besmudge the die cup.
Both of these are also in permanent installations and cannot be beam-profiled.
