Price varies by region (YMMV). Home Depot has the Husky 500 Lumens LED Dual-Panel Utility Light (99877) on sale for $7.88 with free in-store pickup or $8.99 shipping to home.
I picked it up with a code from one of their pickup lockers, which was pretty slick....didn't have to wait in line, just entered the code at the locker location, it was quick and easy....great light to have on hand, nice quality.
If one is available in a HD near you I highly recommend you buy it, good value.
