Question

Halogen recessed light question


I have a set of halogen recessed lights and in the instructions it states:

--The clearance space above the lighting fittings shall be a minimum 1/2" and the lateral distance from surrounding building or insulating material shall be a minimum 11 3/4".

Well how am i going to mount this between the joists if the lateral distance is a minimum of 11 3/4" on each side? The joists are only 16" apart?

Got a part # so I can read it for myself?

Contact the manufacturer and ask them. They wrote the specs.
Personally, I would have no issue with installing them as you intend in my own home, but in someone else's, that would be another story. They do get awful hot.

Get a different fixture or you would need to cut a joist out where the light goes and do some support framing for the cut ends of the joist.

This type of thing is done when installing a chimney up through a ceiling. Sort of like the following but may need to double up on the cross members for better structural support (ask your building inspector)...

Yeah, I'm not doing that, that's ridiculous.

Dimensions don't sound right; only 1/2" above yet >11" on the side? Doesn't heat rise? Why less above than laterally? I bet there is a conversion from metric to SAE that got screwed up. Best to call mfg.

You don't know the manufacturer or part number? It is printed right on the fixture.

I agree, something sounds fishy with the 11-3/4" side clearance to combustibles, but further investigation is needed to determine if it is in fact a requirement or a mis-print.

Nope it's the real deal those are the spec, apparently these things get HOT:

I may go to HD and get some new ones for the bath. I could use these in the garage or take them back but the requirements are ridiculous.

The requirements aren't ridiculous if they get super-hot. After long term exposure to high heat, framing lumber will become much easier to ignite simply by temperature as it loses nearly all of its moisture content.

It's ridiculous that in most circumstances I would have to construct a sub- ceiling just to use a few halogen lights. Better just get some lights without the stringent requirements.

+1. That would also be a red flag in my book.
