I second the Thorlabs LED: I've used the white one for some illumination work and it does a good job.
If you are interested in 'rolling your own' you can buy insanely bright blue power LEDs. A company I've gone through in the past is LuxeonStar:

You can thermal grease and bolt it down onto a heat sink for a computer processor and it shouldn't melt when you run it... @:-) Don't look directly at it while it is lit.

Hi Caroline,
I'm a big fan of the ThorLabs LEDs. They're cost-effective and come ready to go for all major microscope brands (Olympus, Zeiss, Nikon, Leica). I haven't done it myself but the collimating lens and mount should make it easy to put on a light guide.

It's about $350 for the intial setup (mounted LED, collimating lens, mount/threads for microscope) and additional colors (mounted LEDs) can be had for about $100. (yes, less than the cost of Hg bulb for 100k hours of use... sweet!) Also, they sell a power supply for $250 or you can build your own for less.
No commercial interest. Just a happy user of cheap LEDs who's delighted to not be constantly changing Hg bulbs anymore!

Hey Guys,
I'm trying to find a blue LED light source for a cheap GFP dissecting microscope. Does anyone know of a cheap illumination system, I basically want a standard light source with gooseneck light guides, but instead of a white halogen light I'd like to have blue light of a wavelength appropriate for GFP. I've been playing around with 3W blue LEDs but I don't have a good way couple the LED to a light guide. Any and all suggestions are welcomed!
Thanks,
Caroline
