I think everyone lost interest in this LED as most have moved onto the “flat white” OSRRAM LEDs, including me. They are obtainable on copper bases and can be driven to high currents.

Would not an osram have horrible lumen per watt, and, too narrow beam. The human eye cone region is 15 degrees. However, 12 degree lights have enough bleed to cover most of the eye cones. Going below 8 degrees, starts to get where there is not enough usable Hotspot. Also, I never liked any light driven above .1 C, with anything less than 133 lumens, which is still very 2011 to my expectations. (most my current generation lights that I like are as close to 200 lpw as possible).

What would the specs look like, with an osram in a 20 mm smo, limited to a single amc7135 350 mA?

Horrible (1020 Lx according Led4power)

350 mA isnt much, other LEDs might do more Lm/W, but with this LED we can easily outthrow any light, just for fun, just because we can

My first run in with osram was with cheap Walmart headlamps, too cheap for optics.

I think I read 40 lpw, and Google won’t say.

I have had xpc and xrc lights with too narrow of a beam, which I threw away after years of trying to use. 80 lpw generation, pre ansi days. I have one xpl hi, which I put in a 31 mm, at 2 watts, the Hotspot is too intense and color too rainbowed. Still use the light but seldom at the full 700 ma. My guys prefer the xpl v6 in the 31 mm. I prefer 35mm smo with the xpl at 700 ma, but it is, or was, hard finding this size. 31 mm barely cuts it. But it does.
