I'm not totally suyre what question you're asking, but the requirement for a 'fire rated' light fitting relates only to the (presumably 'intumescent') seal between the fitting and the ceiling, such as to prevent spread of fire from the room below to whatever is above, doesn't it?

Do you think the sealing on this open type is more comprehensive than the enclosed types?
Dunno - but if it really is 'fire-rated', in the usual sense, then I suppose it must be, even though there's nothing one can see in the photo which suggests that.
If my understanding is correct, the odd thing is that 'fire-rated' does not seem to 'be concerned' about the possibility of a fire being started in the above-ceiling space by the (presumably 'over-heated') light fitting - but only about prevention of fire spreading from the room bellow to whatever is above. Is that correct?
Kind Regards, John

If instructions are adhered to, why would a fire start in the void?
As opposed to the possibilities of a fire starting in the room space below, which are more numerous.

Sure, but why does anything electrical ever start a fire (if properly installed)? Faults arise - and even design faults (or faults in instructions) sometimes take a fair time to show themselves.
Those who created the rule (as I understand it, maybe not correctly) about fire-rated fittings etc. seem to think the same way as you!

Yeah, I'm not saying it's impossible, I'm just saying the other is more likely.
They work by the fact that the front is totally sealed, being made of metal and glass, which are fire resistant materials. The lamp is installed from the back by removing the whole thing from the ceiling.
The can types rely on the metal can as the fire resistant part, as the front is open, lamps installed from the front.
