Re: What is everyone\'s favorite long run led light?
Favorite long running LED? Hmmm.
Kinda depends on what you mean.
Longest running, most compact, least expensive battery...I'd say the regular Infinity (I like the Blue-Green). Plus, it has the option of NiMH (for ultra cheap battery power) or Lithium (for cold weather performance and REALLY long shelf life). Get's about 40 hours of light from a single AA.
Most compact but also most versatile but bright enough to use for almost all flashlight usages...PT Attitude. It is unregulated so it will suck every last electron out of its 4 AAA batteries for really long runtime if that were ever needed. For myself, I run it on 4 NiMH AAAs and just recharge it once every 1-3 weeks whenever I notice it dimming a little.
Best single LED light...if I could only buy one and nothing else...very likely the ARC AAA. No other light embodies such a good combination of small size, long run time, brightness and will still fit on a keychain. But...having said that, mine just sits on a shelf. I use a Photon on my keychain for occasional bursts of light, a Blue-Green Infinity on Lithium for an emergency light in my car, an Ultra on a lanyard for a great light to use around the house or casual walks and finally the PT Attitude which fills 95% of the needs I ever have for a flashlight.
