So what's the next step beyond the R2

[pertinax]

Obviously, we can look forward to more "real" white lights (rather than the blue can't barbeque color), but after the one die/200 lumen point, what's on the drawing board? I don't keep up with the industry, but I'm wondering, are we now at a long-term stable level in brightness? Or is there some more efficiency coming in the near term?

Just wondering.

I may be wrong so correct me if I am but I think even the most efficient LED's are only 45% efficient at converting electricity to light and the rest is lost in heat and resistance and thin air JK. I would hope that there are some really smart people out there working for these big companies or even someone in a garage that is thinking I can make that at least 15% more efficient which would translate to better battery life or brighter lights. As long as there are advancments in the semiconductor world we should see advancements with LED's. Although I do like the quad die approach it seems like a stop gap or a cheat. Hey look over here my car has more horsepowere than yours well of course it does you put 4 engines in it hehe. Oh well I just hope that sometime soon we could see very good efficientcy out of a single die somewhere olong the line of 200 lm/watt. I would love to see 800-1000 lumens out of a xp-e or xp-g package.

Ever hear of the VW W8 engine? LOL

I think the multi-dye LED's are great. what if you need a small super bright light, where battery life is not that important. I am making a 2400ma 3-mode MC-e drop in for a surefire light of mine. I also have a few R-2 drop-ins. I just swap them depending on what I need. :candle:

Single Die = SST-50 / R3 and R4 / Hopefully better Luxeons / and better SSC P4s . Diamond Dragons = To hit or miss , I had 3 and only one of them performed as advertised .

Just wait for SST50 and SST90 light to be released.

I think it is time to stop making leds brighter and concentrate on making them more efficient. An output of 250 lumens is more than one person would need from a flashlight, but ~2 hours runtime is just too short.

Would be nice to see 250 lumens for 6 hours with a single 18650 by using a high efficiency led.

and of course, the Cree XP-G emitters . . . .
