At first, I jumped on the LED bandwagon with some expensive Streamlites. Then, I thought I'd try some of the Harbor Freight 9-LED units that can be bought on sale for something like two for $2.89, give or take. IMHO they are a good bargain. I keep one at every machine in the shop, every vehicle and one in my pocket. Besides that, I give them away to folks who haven't tried LEDs, yet. They've done the job well enough.
I've only had trouble with one, but a bit of solder and epoxy turned it into the rugged unit I always keep in my pocket. That said, there seems to be two designs, one better than the other; you'll instantly recognize the better one.
BTW, Harbor Freight's recent flyer featured a coupon for a free 9-LED light, same as the lesser of the two units.
Granted, there's no snob appeal to these cheapies, but what the heck...
