Leave it as is? It works.

Convert to "HMI" CMH

The Cool Lights HMI discussion has piqued my curiosity about just how this could work.

Leave it as-is and get a large chimera for it, at least 4'x4', but maybe larger.

And of course dedicate one 20amp electrical circuit to it. If you don't have a circuit for it, then yes, it's a candidate for freakish hybrid experiments or sell it.

Unfortunately, my studio electrical arrangement looks like what was behind the tree in "A Christmas Story."

"A quick flash... a whiff of ozone... and..."

That's kind of the deal. Make an insane amount of light with little bitty power.

It would be a fairly easy retrofit. Just finding the right bulb/ballast combination. Like the 400 watt lumenlabs kit, but there's room to go bigger.

well it depends. is the glass in it good ? or has it gone yellow ? is the reflector good ?

a 575 conversion is one thought if you have the skills & tools. given how ungreen tungsten is, I hate using it now because its just not efficient to use. you can get these lights cheap enough. I would not try a chimera on it because these lights are not the most efficient Fresnel around. better to use an open face if doing a chimera because you get more light per watt. if you want to soften it, a 4X4 silk works well, or frame with 250/251.
