Re: $10 Super-bright police flashlight - bulb and lens

Replacement Bulb
----------------

Get 2

One bulb will be the same voltage and milli-amps as the original.

The other (spare) bulb will be somewhere around 6 volts and somehwere
around double the milli-amps.

You can compare the two and have a spare for an extra $2.
