I've been frustrated in stores that display LED flashlights and brag about light output but don't have a working one to demonstrate it. I took a chance in a Sams Club and bought a 2-pack of flashlights, each with a single 3-watt LED. They're amazing! I use one to shine a light from my kitchen door 50 feet across the road to see if my paper's in its box. It illuminates my neighbor's pole barn 100 feet away. It uses 3 AAA batteries and claims a 20-hour life.
LEDs are showing up in many more places than truck lighting, Christmas light strings and traffic signals: Ann Arbor MI is putting them in street lights.
I'm waiting for the 3-watt LEDs to start showing up in under-cabinet lights for kitchen task lighting. I have 20 halogens over about 15 feet of countertops. 20x35 watts = 700 watts.
LEDs should displace every halogen, incandescent and fluorescent, and ASAP. And for now I should replace my halogens with fluorescents.
