LTM Pepper 300 and Pepper 420 - any difference besides the bulb?

The specs available on B&H's web site suggest they're the same housing, with dimensions and weight the same. My guess is it's just a different bulb, but does anyone here actually know? I've been unable to find a working web site for LTM Lighting - a URL yes, but a working site, no.

Steve, I have somewhere in my storage LTM peppers catalogue. Personally I went for Pepper 100 and using it with 100, 150 and 200W bulbs.
If you like to have more power then 300/600W combination with GY-9.5 bulb base is very common in lighting for TV/video/movie.
For my location interview kit just for size issue I went with DeSisti, but if I'm doing it again it will be Arri 600.
Using 420W bulbs in open face instrument (EKB; 120V/420W; 3200K;75H average life) never give me long bulb life as it's average life shows.
In my "cheat" bulb lists for Pepper 420 it shows for 120V only 400W and 420W option, all other listed bulbs are for 12/24/30V. Kind of limiting factor.
Fell free to ask me more?
Good luck!

Here we go:

Sorry, in my previous post it should be 300/650W not 600W

Thank you for the catalog pages. It looks like the only difference between the two might be the lamp socket. One say "double contact bayonet" and the other is "2-pin prefocus".

You are right Steve, only difference is in the bulb sockets. "double contact bayonet" bulbs for 120V are ESR-100W, ETC-150W, FEV-200W, ESS-250W (a little to big & strong for pepper 100).
"2-pin prefocus" was very popular bulb socket for Lowell Omni and similar open faced instruments. It has one thicker and one skinny bulb leg. Typical bulbs are: BHC/DYS/DYV-120/650W;
FTK - 120/500W; EKB-120/420W.
Your catalogue is on the way!
All the best!
