Attic Box/Light Requirements

Quick questions regarding lights to be added to my attic:

1) Do the boxes have to be metal?

2) I'm assuming the lights must be enclosed?

Would "enclosed" include something like this? Ignore the motion sensor part - but just the two-headed design.

There is no Code requirement for the boxes to be metal.

I also don't know of any requirement for your lighting to be enclosed. There are requirements for closet lights. Typically a bare bulb porcelain socket is used, at least in my experience.

Box doesn't need to be weather proof or metal. Those you pictured look a bit pricey for an attic. You might consider a couple of switched receptacles and hang a couple of four foot florescent shop lights. The receptacles would do double duty giving you a place to plug in should you need to do work in the attic.

Is this a attic that is used for storage with a floor? Or is it just the trusses/rafters and insulation? Either way plastic boxes are just fine. Unless you think that the light bulbs will be subject to physical damage (IE: your head) just a keyed/key less lamp holder is fine too.

I always use faux porcelain fixtures with CFL bulbs and your standard round NW gang box.

Can you explain what a "keyed/keyless lamp holder" is? That's not a term with which I'm familiar.

One of the mystery terms of the trade till you understand. The ones you most often might have seen are a very simple white ceramic bulb holder with either a 3inch or, more commonly, 4" base. They cost about a dollar or two.

Keyless means no switch from the old days when the switch looked like a key.

Those are the faux porcelain ones I mentioned (plastic). I haven't heard that term either...

There are restrictions on ceramic/porcelain luminares which I think may only be limited to closets... Maybe basements too. Don't know. Best just not to use them at all IMO. In fact, I'm not sure where you can even buy them anymore.

The plastic ones are dirt cheap. No need to get crazy with florescent ballasts and the like for an area that will see no traffic.

Yes, Thats them. I also would get the plastic ones over the porcelain. I always turn the screw one too many times and break them. You can not use them in closets because the incandescent lamp must have a cover over the lamp. Even if you used a CFL I don't an inspector would pass it because somebody could easily change the lamp to an incandescent.

Not sure of your budget but Lowes sells some real neat shop lights that use two 35W T8 bulbs and are rated to 0 deg F start. About $17. You can get all color temp bulbs. They are bright. I have 4 in my attic and one in my shed. Very nice.

Plastic boxes, keyless fixture with 75 watt A lamp, and a switch at the entry to the attic.
Done, finished.
