I have an Elmo projector which takes the EJM lamp, I recently saw lamp with the code EJV, same voltage, same wattage. Are they interchangable? What's the difference? Thanks

I'm not a bulb expert...but the differences read in the detailed specs. Specs can also differ depending on manufacturer. Doing a Google search both the EJM and EJV appear very similar...Identical in color temperature 3400K...40 hours (except Osram lists EJV at 100hrs)... size identical. Specs differ in filament design and Luminous Flux (LM) and the EJV generally costs more.

EJM: Filament = C8, LM = 170
EJV: Filament = C6, LM = 270

Both will work in you Eumig...just depends on your usage.

BLT Direct have both lamps.
Their EJM is £17.64 and their EJV is cheaper at £13.46.
Why not try an EJV and see how it compares with your EJM?
