Thread: 200 white lumens for 1amp!! NEW K2's

    Default 200 white lumens for 1amp!! NEW K2's

    It even says the max current is up to 1.5 amps! So I wonder what the lumens is at that current. 230?

    looks like the k2's have almost caught up to the Seoul's and Cree's. Almost.

    I'm glad to see that they're catching up. I hope we see some colors in this performance range soon.

    RECALLED by manufacturer.

    I don't know if or when they might actually be available. Phillips Lumileds will be taking a beating over this one.

    (if you read my post in that thread, there is also a part number for a 220 lumen LXK2-PWC4 that is also being recalled)

    Sounds bad... but... brighter LEDs will be out there no matter what. Whether sooner or later, by hook or by crook...

    ...just like when everyone was waiting for the K2.

    I only hope that THIS time, the results really ARE well worth it. I mean, I never found a K2 to be all THAT much better than a Lux III. At least... was nothing to write home to Krypton about, heheheheh.

    So, here's hoping that WHATEVER company does so... they do something like "320 lumens, 3.4Vf, plenty of color choices, heat about the same as a Lux III or K2". And don't forget the optics. Oh, and a strawberry shake, please.

    Yeah I will take a 400lumen darkside, 400 lumen good side oh and 1amp with 3.6V.

    Oh and make that with the same luxIII/k2 optics and have the mmounted on teh stars that the luxIII and luxV stars.

    I have problems trying to solder to the k2s.

    I have 3 of these on order right now. I just received an email stating that the problems are resolved and I should get my 3 200 lumen K2's around April.

    I can't wait to power those babies on.

    Actually... that's Cree/Seoul's goal. They have a chart for their goals to get to 100 lumens per watt (3V and 1A for 300 lumens). They aren't horribly far either... the P4 is 240. The Q5 stuff has been out and R's are just trickling out.

    At least for whites that is. There isn't a good color push though as with flashlights. I think I remember reading though that LEDs for colors would top out in the next few years because they'd simply be as efficient as the technology allows.

    Well, I'm game (as is most everyone else) when a recognizable "upgrade" can occur.

    After all, that is why I prefer powering things at 7.2-ish volts and letting the driver do the conversions/controlling for current... because even as single LEDs get more "power-hungry"... they *SHOULD* be able to get "thrown inside" the Flange III sabers with little issue.

    I'm only worried if the heat keeps rising and rising. Then again, the sabers are handling the K2 @ 1500 just fine.

    Wow, 320 lumens! That is just crazy. I hope that happens soon, I bet we all do.
