Review on Cyclops HATCLIP LIGHTS CYC MHC G Headlamp: Illuminating Adventure on-the-go! by Steve Modesto

It's amazing how bright 5 green LEDs can be. I carry it on my hat all the time with no problem, and it's compact enough that it doesn't look outrageous. You can install from above or below. I tried both ways and preferred the lower way. Again, it's so compact that it doesn't obstruct the view at all. I would say it puts out a good 10-15 feet of light and then some more. I recommend this product and was pleasantly surprised by its brightness and ease of use.
