[GreenKeys] Spare bulbs for model 28 copy light, margin light

Wed, 23 Jan 2002 00:06:04 -0500

Don,

The lamps in mine are #1814X 6.5 v. 6 candlpower 500 hr. life
The specs on the #82 are virtually identical to the 1814X.

The #64 lamp is a 7.0 v. lamp 1,000 hr. life and @ 6.5v. would last about
3,000 hr. and be about 2 candlpower.

I still need to get my 28 running instead of using it as a door stop, but
I'm still stuck in Atlanta, so it will have to wait until I get moved.
