Can I run an m59/e rated lamp on an m59 ballast?

Can it be done safely? This is a SE lamp and one of the few 14k lamps that isn’t prohibitively expensive. It’s also listed as HOR and my setup, a high bay lamp I modified to fit my canopy, is vertical. I thought all modern lamps made for reefing were universal mount.

At least if I could safely run the lamp on a magnetic ballast I could grab a horizontal reflector and use everything else I already have. I’d have to ditch the reflector, which lights my 90 gallon cube up quite well. I might just stick with my 6500k for now.

What would happen to a lamp rated as HOR if it was mounted base up? Would the heat melt the glue or cause the lamp to explode? Would it just reduce the life of the lamp? I’m just curious, because if I could run the lamp safely, even with a shortened lifespan (say, 30%), it would still be worth doing assuming I’d still have a 14000k output.

I’m not going to buy the lamp if there’s a greater risk of fire or explosion than the norm. I’m also not going to buy it if it won’t put out a 14000k color temperature on my core and coil ballast. Of course if we’re talking 15000k or 13000k that is acceptable. Maybe even 16000K. I realize that not all 14000k lamps output a true 14000k color spectrum to begin with but that’s another story.

M59/E bulbs are designed for an ANSI M59 ballast. The E is the fixture rating, designed for use in enclosed fixtures.

Certain halide bulbs must be operated in a specified position only. Even the popular Radium bulbs are only rated for horizontal use. These bulbs are optimized for that operating position and using any other position will cause a color shift, reduced performance and could cause the arc tube or bulb seals to fail permanently. Increasing the risk of an arc tube rupture or fire.

Some choices for vertical reflectors with a M59 ballast:

Ushio CWA models in 10k, 14k, 20k

Iwasaki Clean Arc 6500k (MT400D/BUD)

Hamilton 10k, 14k, 20k

Plusrite BDX (20,000k) MH400/ED37/U/BDX

Ok that’s good to know. I’m going to have to skip it unfortunately then.
