There are several online suppliers of LED flashligh bulbs. Until they come down from their current $30 price (or until batteries begin costing $10 each), these will be attractive only to survivalists and special purpose users. The same logic applies to special "energy saving" bulbs and the cost of electricity. It just ain't worth my while to buy a lightbulb that takes five or six years of energy savings to pay for itself. You can get a nice little LED flashlight at Walmart for $8. It's called a Dorcy Cool Blue. The light is very white and stays that way even as the batteries weaken although it does get dimmer. To me the whiteness of the light makes it seem brighter than it really is. It works well for most tasks around the home and it's nice knowing the batteries won't have to be replaced for a long while.

Thanks, I'll check it out. Meantime, I'm thinking about
this mod!

I never got over my childhood fascination with shiny objects and bright lights. I bought a keychain LED flashlight made by Inova. called the Micro-Light - that was on display at the checkout counter at CompUSA. It uses a red LED, but it claims visibility at one mile and the battery life is probably a couple of years under normal use. It lists for $9 but I used a corporate discount to get it for under $5. Apparently, Inova has
a whole line of LED flashlights.

Number 27 is also for you.

My headlamp is made by PrincetonTec. They have a website: www.princetontec.com.
The headlamp I got is called "The Matrix".
I got it at either an REI or an EMS. I can't remember.
I also can't remember what I paid for it. Sorry.
