FYI,
Just bought a package of 3 LED headlamps at Costco for $8 with coupon.
They have 10 LED's in the lights.
Three settings. Low - 3 LED's. High = 10 LED's and Flashing
I picked up a pack last weekend. Used them this weekend camping. They work great. They have three modes, Bright, Brighter and Strobe. They even fit my 4yr old's head. Great buy IMHO!
