Here's my UV-modded XNova done by our own WildRice. Background story is I had bought two XNovas to give as Christmas presents but both of them had issues that left me less than thrilled. I got a silver one that was very bright and very blue/white but it had a bit of a flickering problem. The pewter one didn't flicker at all, but the beam had a lot more of a greenish tint. I wasn't overwhelmingly happy with either one.

I had done a couple deals with WildRice before and asked him if he wanted to try his hand at modding an XNova and he said sure. At first, I was wanting to use the 26,000 mcd white LEDs that everyone is talking about. I have no doubt that that would have turned out nice and bright but since I already had, oh, a dozen or more nice bright little lights, I decided to have him put in some UV LEDs.

I already had 4 other UV lights plus a small blacklight, but the idea of a UV XNova seemed intriguing and I figured there was a chance no one else had one.

The LEDs he used were spec'd at 395nm and I even had done a MiniMag knockoff using the same LED, direct driven on 3 cells which made things flouresce quite nicely so we used those LEDs in the XNova. What is surprising is how much less visible light the 5 LEDs of the XNova put out compared to the single LED MiniMag nockoff. I don't think the modded XNova makes things flouresce any better than the single direct driven LED, but since there is less subviolet (can I say that?) light, it seems like the XNova is better.

Here's a pic of the light itself:

And here's a beamshot of the same target using the XNova:

I still don't understand why this occoured. But maybe the single led is overdriven more and produces more visable light than UV when overdriven?

I never payed attention to the Xnova, or Inova's because I like luxeons for output. But alas there are no UV luxeons, and I like AA's more than 123a's, so this Xnova will be a great host for UV leds. Thanks cratz2 for the insperation! I've been searching for a good host for some UV leds and you found it! /ubbthreads/images/graemlins/wink2.gif

Now I just gotta find one in titanium or black. Amondotech has the clone of the xnova for cheap, I might end up with that when I order my batts from them... I'll search ebay some more though. I'm anxious to get this mod done even if my leds are only 400nm, I like purple light anyways! I got lots of GITD stuff now to charge up, and things to *inspect* /ubbthreads/images/graemlins/grin.gif
