Just noticed that theledlight are now selling turquoise leds. Well, they may have done for a while and I didn`t notice, it`s been ages since I went looking round their site, but I got bored at lunchtime today...anyway- Has anyone ever bought some of these LEDs before....

What are they like? Are they the same as those used in Photons, or more like the Infinity? The quoted brightness seems a little low for the Photon`s LEDs.
Just wondering...

I love the turquoise 20.8 Candela LED. The only problem is that you have to buff or 'lightly frost' the LED. The E2-LED conversion and the turquoise mag conversion are my two favorite carry LED lights.

Thanks, I do know those leds but theyre too narrow for my needs. I`m not actually after them for a flashlight, but decorative garden lights! I`d love to see how well one of them does in an e2 though.

A while back I shone my turquoise Photon-II at a bush that was lit by a 12v 21 watt (green filtered) spotlight (part of a set of 4 dissapointingly dim lights) and it was brighter! I shone it at the same distance as the spotlight, held next to it and did an "alternating-lights" test covering/uncovering to see which was best.
So anyway I want to outfit my garden lights with LEDs this spring and hopefully in the summer get them all running off solar power! Those turquoise LEDs are just the right colour to show up brightest on all the plants and bushes, blue or emerald-green appear darker in comparison (though my old Nichia blue and greens are probably old-chip (green is 6000mcd), I have yet to try the new-chip (10 000mcd green) ones too.
I have a pair of solar power LED marker lights but they`re fairly uselsess as illumination, just glow yellow, so my goal is to have brighter lights than I have now and using about 1/10th the power making solar power feasible in our not-too-sunny climate, ie with LEDs.

I think I'm going to make the E2 LED lamp with this Turquoise LED and see if anyone is interested. I made one for myself and it's pretty nice. You do have to sand the tip of the LED a little to make it look smooth.

Brad how does the turquoise compare to the white model? Can you take a side by side shot?

It's real bright. Lights up the whole room at once. The one I made was from the turquoise LED out of my Photon. I'm not sure if it's the same as the turquoise B.G. Micro LED I bought a while ago. I'll buy another one from B.G. Micro and make another E2 lamp with it. I'd like to see if it's the same.
I don't have the camera anymore. I might have to take the pictures at work. I'll let you know when it's done.

Brad,

Just how much do you have to sand the tip of the B.G. Micro 28,800 mcd LED? Is it just enough to frost the end of it or do you actually change the shape of the end of it? I'd really like to hear what your procedure is to get the best use from one of these. Thanks

I just frost the tip with fine black sandpaper. That will get the rings out of an LED. It will be slightly dimmer but I think the trade-off is worth it to have a nice even light output.

Steel wool works very well for this. I've tried #400 black sandpaper and it's a little too rough. My steel-wooled Photon II turquoise is nice and smooth.

I use 1500 grit (because I have some), don't need to polish afterward and only do the 'dome' ... not the sides. The few I've done this way give nice even illumination, no rings and focus nicely in the 2AA Maglite.

Good luck.
