Those flat, round, LED, non-can ceiling lights


My wife, the Victorian decorating maven, suddenly likes these lights.

I've got a pic from the web, not exactly the same brand. 5' across, only about half an inch thick, trailing a transformer, 12 W.

No instructions came with them, nor do I find anything very usable on the web.

They look as though they are really meant to be mounted in a simple hole in a wall or ceiling, sheetrock only, and not very thick sheetrock at that. Held in by a couple spring clips. There are also a couple ears extending up from the back apparently for some kind of mounting situation. Not shown in this pic.

I'm accustomed to an electrical box with the fixture mounted to a strap across the box. Looks like you could just kind of slap these in. Suppose where we want a string of them I'd properly have to put in boxes to contain all the splices.

Thing is, at least one place the boss wants one is on sheetrock over a lot of wood.

So actual question #1 is, do I need to chisel out some space in the wood behind this light? Do they generate any heat? Need any clearance?

#2 can they be used on a dimmer switch?

#3 What should I be asking if I were not SO uninformed?

Thanks

The way your post is written, your fixtures are 5 feet in diameter. I'm guessing you meant 5 inches. The ones I've seen are either retro fit for can lights are will fit into a junction box.

If you can't find meaningful info about your product then I'm with ritelec, no listing, no instructions, no install.

The way my post is written, that's not a pic of the product in hand.
Writing on the box is Chinese. Label on the transformer or whatever it is says Triac Dimmer Constant current. There's a schematic of sorts.
No UL. CE, yes. Double insulated symbol. Also an F in an inverted triangle.

Label on back of light says AC: 85-265 V
Power: 12W
Color Temp:4000K

I cannot find installation instructions that come near my house's peculiarities or answer the questions above.

I don't think these are mystery appliances. I will ask my wife exactly where online she bought them and try some questions there.

These would go in cans, but I don't have cans. They are bigger around than any box I've seen, but those ears might mount on some kind of a bar that might go across a box.

Hope I haven't made any more typos!

There's plenty of ul listed products.

I wouldn't install these. IMO

NEC and building inspectors require a ul listing and if the house burns your insurance may require one to if you want to be covered for the loss, Just because you can buy it doesnt mean its legal

Those lights are meant to be mounted directly to gyprock ceiling

I think you guys call it sheetrock,

No box is needed,

they are so light the gyprock can easily hold them.

In Australia we do not need boxes for light fittings
not unless they are heavy in which case we would
use some wood or metal brackets.
But most domestic light fittings are so light the gyprock
can hold them easily.

I am not sure what you codes allow,
Is it mandatory for boxes on all lights ?
