Thank you for looking

First different colored Aspheric Mod I've seen, I'm guessing the beam is quite visible at night.

[katsyonak]

Yes it is, I really didn't think it would be like that, but the beam is surprisingly visible at night.

[LukeA]

Very nice.

You know you can focus it tighter? You lose the die projection, but get a tighter, brighter spot.

[ICUDoc]

FULLY freaky appearance on those walls- it looks like it sits in space, not on the building wall!!!
I guess that's blue light for ya'.
Thanks for the look!

[TorchBoy]

Please don't forget to keep pics to 800 pixels wide. Thanks.

Done. Sorry about that

Will try that, I didn't play much with it's focus actually.

You're right, it does look like it's in mid air before the building

Do yourself a favor and DON'T look into that beam unless you're at least a 100 yards away. I built a royal blue AA minim@g for a friend and thought it'd be interesting to see what effect the beam had. Immediately afterward I was concerned I had permanently hurt my eyes. This is with a MadMax Lite sandwich, 2 AA alkaline, and a 20mm reflector.. That LiIon powered Aspheric might be dangerous at close range.

I believe LukeA is right. If you loosen the head until it almost falls off, the light now going into your spill goes into the beam. You do lose the picture of the die though. As you turn the head out, the picture sort of comes back but it's never clear like your pictures.
Have fun with it.

Thats really amazing. But why blue? Glow Powder ok, Maglite ok, but why the LED?

Did you have to machine the head, or the lens?

Please post some pics with the highest concentration and a loong distance!

Based on how the LED chip looks that seems to be previous generation Cree XR LED and not the XR-E. With blue XR-E it would be over twice as bright

[crackerkorean]

Newb question, what did you mix with the glow powder to get it to stick?

I gotta try this, thats awesome!!

[Aircraft800]

WOW! That ROCKS! You can scare the kids with that one

Great FUN light! (Now if you can only get it to project the Bat Signal)

[TorchBoy]

Man, that's nice. I presume if you shone it on a red coloured/illuminated building there'd be even more of a 3D effect. If you could get Cree to make the die in the Batman logo shape instead of square...

If a tri-colour LED was used would it just project the three dice next to each other?

The center could be in focus, but the portions of each die nearer the outside would probably end up somewhat blurry.

Thanks for the tip, I didn't know blue light isn't good for you. Anyway, I didn't look into the beam and have no intension of doing it. Actually I rarely use this light as it not very practical.

Well, I bought the LED out of curiosity and had a spare Mag, spare Aspheric lense etc., I never even planned this mod.
I didn't machine anything, just shaved the reflector's lips so the Aspheric lense will get deeper in the head.
I will try to take more pics when I can. I have this mod for some time and the reason I didn't share it here was because I didn't have good outside shots and I eventually decided to settle for those ugly building pics.

I used 2 ton clear weld 30 minutes epoxy glue. I mixed approximately 1/3 glow powder and 2/3 epoxy.

It says "custom order" for the emitter on KD. Did it take long to get it?

[Waffle]

That is very cool.

[KrisP]

I'm making a 1C version with a red cree... I broke the dome off though, so i'm awaiting the arrival of another

I don't remember waiting too long for it and I had other things in that order too. I thing it took maybe a week more than usual.

What driver do you use to run the red CREE? I know that red (and green) CREEs VF is about 2.2V (maybe even up to 2.6V?). I used this driver to run a red CREE for a while, it was very nice but while experementing with it something went wrong and it was eventually fried.

[KrisP]

I tested the red cree with two DX boards, one was the 700mA driver with the AMC7135 regs, I measured the output current and it was around 660-670mA. I also put a 5-mode 1000mA driver in parallel after the 700mA board to get multi-modes which worked well The 5-mode has three AMC7135 regs, so I plan to just desolder one and see how it goes as a 700mA multi-mode driver, when my new LED arrives

[TorchBoy]

I also put a 5-mode 1000mA driver in parallel after the 700mA board ...

What does that mean?

[KrisP]

Sorry, I meant the 5-mode 1000mA driver was wired in parallel to the 700mA regulator board.

So:
Battery -> switch -> 700mA reg board -> 5-mode 1000mA board -> LED.
The first board just limited the current to 700mA so the 5-mode board would only have a max setting of 700mA rather than 1A. Since the red LED Vf is so low, the voltage drops of the two boards didn't affect the output at all.

[TorchBoy]

KrisP, I think that's better described as the first board is driving the second board, not that they're in parallel to each other. It seems like a good way to do it for a low voltage LED.

[KrisP]

Ahhh... Yes, because they're not coming from the same supply, one is actually supplying the other

[TorchBoy]

It seems like a good way to do it for a low voltage LED.

Now that I think about it, why not just disable one of the AMC7135s from the 5 mode board?
