I need a bulb for an OLD projector.
i have the box right with all the info but have no idea where to get one.
info on box
SYLVANIA
projector lamp
DJL blue top
150 watts 120 v 15 hrs

I see no other numbers on the box
I do have some sweet 60s instructions I will try to scan and post up

like CRT projector or one of those transparency types?

Overhead projector?
Slide projector?

Chances are if it’s an overhead an office supply store might have something.
