Good idea but a $2 buy from countycomm becomes $20 (or more) when shipping to Canada. I told myself a long time ago I'd never buy from countycomm unless they stop shipping with UPS exclusively.

Colored LEDs (just the diodes) are easy to come by but are to impractical to try in the field...especially at night. I could play at home but I don't think it would be the same or show me what I want to know...especially since I'm still just learning about how to use these lights to supplement mantracking technique.

I ended up ordering the multi-color flashlights from eBay...they were too cheap to pass up. I got 2. Even if they don't work out for me, I know plenty of people who I could pass them along to and easily get my costs back. If they work I'll have a backup which is nice since these are hard to find new now.

I've also been reading up on how LED lights can be bad for night vision because they are too white or a little blue. There's actually studies which prove that the slightly yellow light of an incandescent bulb is better for focusing on stuff at night because of a lack of blue in the spectrum...I guess we naturally have a hard time focusing on blue light.
