Note: Use a DC wall adapter for power with 1 - 2 Amps output.
ie: 12 volts DC with a 20 watt bulb


Sounds like he's talking about the DC wall adaptors you get to charge cell
phones, portable electronics, cordless phones etc. Just cut the end off,
usually a barrel tip.

On the adaptor it will say something like input: 120v ac, output 9v dc 500
mA. In this case you're looking for something that has an output of 12v dc
and 1000 mA, which will give you a slightly dimmer bulb, but a longer bulb
lifespan. An output if 12v dc with 2000 mA would give you a brighter bulb.

If you can't find one in that kitchen drawer, or your local electronics
surplus shop, or radio shack, then there's always mail order.
