Thread: Color? Cree? UV? What? YAY!

  1. #1

    Default Color? Cree? UV? What? YAY!

    So, Kaidomain has Blue and Red Cree XR-E's on 17mm stars! And 3 Watt UV stars @ 410 nm (visable purple light)

    They also have a 15 watt white that I'm eyeballing for my headlight project, but 20vf @ 800 mAh is a lot to get, and I can't find a single power supply that can handle that...

    Hmm... The UV LED looks pretty spiffy.

    I need to find the spec sheet before I rule on the red and blue...

    At $5, I'll try out a blue. Perhaps someone else can try a red?

    I am very anxious to get my hands on that UV, though. The wife has been bugging me for a true purple saber.

    What the heck. I'll give it a whirl.

    Heh. What is it with the wimmens and the purple? A female friend I'm building a saber for is equally taken with blades at the pink-purple end of the spectrum.

    It occurs to me that the nature of any UV LED is such that it's spending some of its energy budget putting out wavelengths that your eye can't directly perceive. I wonder if there's such a thing as a translucent fluorescent purple dye you could apply to some part of your diffusion setup to bring some of that ultraviolet back into the visible spectrum.

    Hmmmm...

    Um... did anyone bother to look at the dimensions/measurements?

    This is a good example of... YES... there *ARE* LEDs and lights out there that are WAAAAAY brighter than any "single" Luxeon or whatever...

    BUT...

    it usually means the thing is much larger in diameter, and naturally has many more "dies" on them.

    I mean, essentially "a" high-powered LED is not actually ONE thing, it is usually an array of 9 "dies" or whatever they are called.

    Anyhow. Looking forward to seeing what new technologies have to offer, but... I don't really care about LEDs that are 4" x 4" x 4" or whatever. If the specs are wrong, fine... but that is what it says.

    With the exception of the 15W white he posted the others are the same or smaller footprint compared to the standard luxeon star and also single die LEDs.

    Hey X, What are the real dangers as far as the UV goes with a blade with Tim's diffuser in? I've tried research on the net about it but I can't see using a saber with sunglasses on....lol
