I love flashlights!<br> <br>LED's I have:<br><br>Lightwave 3000 - A good light to have for extended use. Gets 20 some odd days, yes days per fill up which consits of 3 C-cells.<br><br>Inova 5 - Cosiderably smaller-poket carry size. 15-20 hours, but uses 2 - 123lithium cells (expensive) Comparible light output to the lightwave. IMO<br><br>Photon 2 - Allways on my key chain. Good light for emergecies - small. I allways have this light on me and my Surefire E1E (not a led).
