    I'm looking for a high power, 300mA (preferably more) Led, in a 5mm package (or equivalent size) in a 10 to 20deg beam size. Can't seem to find a source.

    Thanks!

    5mm as in T1-3/4 round? I found a green one but it isn't very bright at 900 mcd

    probably. Basically the standard radio shack size. Or what you see in cheap led flashlights.

    You buy the LED.. Then you buy the optics. The optics are what gives you a narrow beam.. Typically LEDs are anywhere from 60 to 150 deg viewing angles.

    And by 5mm I assume you don't mean a T1-3/4 LED as I highly doubt there is one with a If of 300mA (most are only 20mA).. Now a 5x5mm is a different story.

    I have seen some 20mA 5mm (T1-3/4) LED's with a 12 to 20 deg viewing angle but never a high power led that can do that without the optics.

    You can buy them, they just aren't consistent. I used something similar for a ping pong ball liquid detector. The bulbs obsoleted on me, and they were always getting silvered on the inside. So I upgraded to LEDs.
