Wood not a safe or legal material for for a lamp
fixture? I suppose neither are the paper shades we use on table lamps huh? I guess we're all in trouble if we've ever used a table lamp on
stage. ;-)
all kidding aside,
Like everything it depends... if you were simply mounting a lamp in a lamp holder, and mounting said lamp holder under a cabinet on a set, that would be 'legal'. why wouldn't it be legal to mount that same said lamp holder sideways, in an open box?
Considering you aren't technically building a
fixture, but combining multiple prefabbed fixtures, I have a hard time understanding where the issue would be, unless it was wired unsafely.
I have personally done what you're talking about. Instead we used a-19
ceramic lamp holders with 5 (i believe) 90
watt par38 flood lamps, wired for
stage-pin, enclosed in a custom wooded trough made of 1/2" ply, painted black. We have since retired them, but we used them for about 3 years with no issues.
If heat is a big concern check the
MSDS for the wood you are considering buying. On average I have found that for my uses they read:
Auto-ignition Temperature: Variable [(typically 400-500°F (204-260°C)]
And use high heat paint if you so desire.
Do you're research, show that you're not being negligent and I don't think you'll have any issues with the
fire marshal. And if it's necessary, you can always
call the
fire marshal and ask.
That has been my experience. If this is wrong advice or not on
par with Control Booth standards feel free to correct me or remove this post.
