Timber and Downlighters

[monkee]

I went to a property yesterday to replace an LV tranny.

The house had recently been rewired I found that the downlighters had been drilled through the timber joist

First I know its structure of some degree secound thay were open backed downlighters more or less touching the timber.

I replaced the light and adviced the agent thay said thay did not want to worrie the client.

I decided to phoned for adviced and thay said you need to apply an engineering approach to it and also check with the manufacture details

when installing down lights.

can you install fire rated say through a nogin I was all ways told to keep it 50mm away from any thing

I am amazed this is still being done

any thoughts what is all you guys doing when you, a install and b when doing PIR

ahhh right - im using the robus ones at the moment (fire rated metal can type) but the tech spec says that they need 100mm either side. I'm stressing because I've only got 55mm to a joist.

i'd not worry about 55mm, most of the heat from the lamp goes up. the can of the fitting will stop heat reaching the joist. having said that, manufacturers instructions must be followed, and in this case i would be inclined to seek advice from robus technical.
