Conventional Fixtures Help! Identify lamp type

[salvee]

Hello All,
Please look at the attached picture of the lamp my customer sent. Can anyone identify the lamp category and letters for me.

Reminds me of the early quartz upgrades for scoop lamps! If it is for an architectural fixture, it very well may not have a letter code. Might just be a number designator (watts, bulb style, size of tube in 1/8ths of an inch.) I would expect you would have better luck looking in a standard lamp catalog then in a theater lamp catalog.

@JD I'd right. I've seen and spec'd it several times, but not for 15-20 years. As I recall, up to 250w, T10 or T12, all of which would be right for the wall wash fixtures shown.

Double globe might have certain thermal advantages for the application and you would be able to touch the globe of the lamp. Slightly higher output than a standard incandescent lamp of the same lamp life, slightly less output than a halogen stage and studio lamp of similar lamp life.

I think the closeup threw me a bit... On second look, might be a medium base lamp more like 150 watts or maybe 250 like these:

Yes those are medium screw. This is from Ushio
