I also like the Cygolite ExpiliOn series of lights, I have a 350 and it has worked fine for about 2 years and doesn't run hot but it's not a 800 either, you may want to try a lower level one like a ExpiliOn 600 these are only $85 on Amazon. The other good light is the Niterider Lumina 700 they run about $100 range also on Amazon. And the final light which I own and like it a lot is the Philips Saferide, this light uses aimed optics like cars and motorcycles do so it puts all the light onto the road instead of tree tops and road wasting a large part of the lumens, thus it has the appearance of a 1000 lumen light with an output of only 240 on high, on low it's similar to my Cygolite Miitycross 480 on high! It will last exactly 2 hours on high then automatically go to low for another hour, or it will run for 8 hours on low. It uses 4 AA rechargeable Li-Ion NOT the NiMh's as Amazon states, and since they are AA bats you can get replacements anywhere. The light is ruggedly made and has not leaked in several rainstorms I was in, plus the lens has a glowing ring effect to it when seen from the side. The only weak spot on this light is that it doesn't have a flash mode because it was made for Europe where flashing bike lights is illegal. The Philips in black is on Amazon for under $100. See this: http://www.youtube.com/watch?v=7fXA1wdm-bQ The beam appears much brighter in real life then it does in the You Tube video, he does talk about the glowing ring might be too bright for some, all you would have to do if you find that bothers you is just take some black electrical tape and tape off the top that you see but not the sides or bottom. And due to the size of the lens which is substantially larger then other bike light lenses, it's immediately noticeable even from a long distance it won't look like a pin prick of light.
