BAS, which piece of research are you pulling on there?

I can't be bothered right now to register on the TRADA site and find the original material (assuming it's there for free), but I doubt that this is a lie:
Whilst there is not a great deal of research information available on this subject, tests sponsored
by the DETR (now CLG) and carried out by The Timber Research and Development Association*
provided useful guidance.
.

.
The above TRADA tests were carried out on typical timber joisted floors (measuring 3.2 x 4.2m)
fitted with up to 24 plastic and metal clipped fittings of various diameters. All indicated that the
unprotected downlighters did not cause premature failure in terms of load bearing capacity,
insulation or integrity. It could be argued that such ‘laboratory’ standards do not represent a floor
after the retrospective removal and replacement of areas of floor decking. Such concerns are
weakened by the fact that patched areas are inevitably supported on noggins or joists and the tests
included decking that was not tongued and grooved. Similar tests were recently carried out by the
BRE*** on typical downlighter and sprinkler head penetrations in various timber floor types. These
reached similar conclusions to the TRADA research.

You can get fire rated tilt recessed lights - such as here

You'll be better off for it as otherwise all sorts of dirt/dead insects end up in the lights

But I'm not worried about dead insects, and I intend to fit LEDs into the fittings. And so many advertisers don't even tell you the tilt angle their product offers.
So many electricians misunderstand this topic and seemingly through misselling these are being pushed on me. If there was a safety case backed up by the regulations or research I would be happy to give in.
I would rather save the extra money and buy more smoke and heat alarms. Far more effective.
I have asked the electrician to show me where it says we need fire rated fittings in the regulations but I don't suppose he will.

not sure I get the reply - but perhaps you are thinking that the tilt won't enable you to retrofit LED lamps as they are larger than normal lamps? You can get good LED's now that are the same size.
Also dirt and dead insects collecting around the base of a lamp do present a possible fire hazard.... and even LED's build up heat.
I think it would be cheaper to pay the extra few quid for a fire rated fitting than to buy smoke/heat alarms and get them installed

It seems to be a common misconception that "fire-rated" (or whatever you want to call them) lights must have some kind of IP rating which automatically makes them OK to use in bathrooms, will stop insects getting in and dying etc.
This is not necessarily the case - their job is to block the passage of fire and fire products by closing paths through the light by having components which expand when they reach temperatures of several '00° C. In normal conditions there's no guarantee that the light will stop anything passing through it or getting into it.
