This weekend we experienced a power failure, and the bulb on my
conventional 2 D cell flashlight burned out. Fortunately I had a spare
PR-2 on hand.

For a replacement I went to my local hardware store, then Home Depot
and finally Sears. Surprisingly none of these places today sell
ordinary PR-2 flashlight bulbs. In desperation, I came from Sears with
2 HPX20 bulbs, Xenon, which are stated to work with any standard 2
D-cell flashlight.

Fortunately I have a good supply of the PR-13 bulbs used in the 6-volt
lanterns, although the stores do sell the 6-volt batteries for these
things. I purchase one of the batteries at a cost of about $9.00, while
the last one I purchased was priced at $3.95.

Strange world! What the heck is going on?

Flashlight bulb?

Isn't that the century old device that we replace with an LED?

The replacement LED assembly in my AA Mini MagLite has half the lumens
of the original krypton bulb, but gives 10 times the battery life -
and retains the beam focus capability.

White LEDs are *cheap* - You need a little over 3 volts to operate
them (fine in the 6volt lantern) and a simple boost circuit for the 3
volt (2 cell) lights.
18000mcd 10mm White LED (about the size of the end of a Sharpie
marker) $8US for 20, including shipping.
13000mcd 5mm White LED (half that size) are $12US for 100, including
shipping. www.ledshoppe.com

At 12 cents each, I'm adding lights to the inside of a closet door
(one LED for each shelf) and anywhere else the wife wants more light.
Low voltage (under 5 volts) lighting at 20ma per LED is safe and easy
to do.
