yay lm301b influx strips

[sdfoster22]

How come the lm/w seem so low on these? Or is that with them ran at max?

[unkle_psycho]

Surely not max. The lm301b is not that much more efficient then the lm561c. A little. But 192lm/w 55c 1000ma seems a little harder driven then the q-series, where the lm-301b gets around 200lm/w. I think. Lazy to check the q-series docs now..

You can hit ridiculous numbers on these if you drive them soft. But until now F-series offered more potential for efficiency, because if you bought equal $ of F&Q, the F would be more efficient.

That's what I thought.

A lot of things happening around Samsung and growing these days...

[unkle_psycho]

Yeah lots going on. They also have new 1w chips that put out 205lm/w, and new 3w and 5w chips. The CSPs are interesting...
