Thanks for that!
I took a look at those Luxeon leds.
The datasheet says they put out only 65 lumens (as opposed to the 1000 lumens I believe a 100 watt bulb puts out) yet people say they're super bright and leave afterimages on their eyes when they look at them. Now, I would assume this was because the beam is narrow, but the datasheet says the beam is like 140 degrees. I don't know what to make of that.
Also, from that site I then went to Digikey to see if their prices were better, but I couldn't find the LEDs there. I did however find the aluminum PCBs to mount them to cheaper.
But then I found the Luxeon website, and it appears they actually sell direct. And I can get the leds premounted on the aluminum PCBs, and I can get lenses for them too. Plus they even sell dimmable constant current drivers for the LEDs. And there's a wide array of color temperatures available and colors other than white as well. I think I've found my source!
But there's one thing that bugs me. The lumens.
The LEDs you linked to, the Luxeon IIIs... Those are at the end of their life. They're not being made anymore. Those are the ones that are 65 lumens. And people said they were super bright.
But the new Luxeons... the Luxeon Rebels... They're 2-3x as bright, according to the Luxeon website. Is that going to be too bright?
Also, another little wrench was thrown into the works when I noticed while Luxeon sells direct, they don't seem to have a whole lot of stock on hand. I don't want to have to wait 3 to 5 weeks every time I need an LED. So I searched Octopart to see who else might carry them and have them in stock, and the only place I found was FutureElectronics:http://www.futureelectronics.com/en/Search.aspx?dsNav=Ntk:PlainTextSearch|3417276|3|,Ny:True,Nea:True
Oddly, even though they carry the Rebels, they're quite a bit cheaper than the Luxeon site, and the lumens listed are more in the range of those Luxeon III's on Sparkfun's site. I dunno what's going on there.
Other than that, the only concern I have with these is I'm not sure how I'd work them in with my idea for animating several in a chase pattern. I can't fit a ring of these in the trap because said ring, if made up of the starboard heat sinks, would end up being too wide. And if I mixed and matched these with dimmer leds they'd probably outshine the other leds by an order of magnitude and you wouldn't be able to see the animation.
But I like the simplicity. It's almost a plug and play solution. Perhaps a single pulsing light would be sufficient. I could animate the bargraph at the same time to add some interest. Hm.
Just noticed they have leds mounted on 10mm squares too. That gives me some more options. Though at almost $10 each, I don't think I'll be sticking seven of these things in a single trap.
