Spot light question

[liambroad]

A bit of advice is needed chaps , got called to a house today to complete spoitlights that the owner had started basicly he marked out and cut the holes out where he wanted the lights and wanted me to wire up the lights he got from BBQ they are 12v 25w halogens. problem is that one of the spotlights just missed a joist and is about 10mm from it , i need to know is there anything i can do to stop the heat getting to the joist ? As a last resort i know ill have to redo his holes , but i can help it i dont want that. any suggestions ?
thanks alot.

can you blank that 1 off without the pattewn then looking like a dog's breakfast, or move it a few inches and patch the original hole?

Personally i would move it. There will be a min distance in the instructions that they have to be installed from joists etc.

The other option is to replace them with main fittings and LEDs

Is the rest of the light exposed and able to disapate the heat into free air, can the transformer be place away from the beam? If so, I'd be tempted to just fit it.
Moving lights adjusting the pattern etc would be a nightmare!

I had a similar one to this and fitted some supalux to the joist as protection. Checked back on it several times and no sign of heat damage so I guess its doing its job.

I know it's far from ideal, but maybe you could protect the joist from heat damage by using something like this...

Toolstation > Hand Tools > Plumbers Torches & Accessories > Burn Barrier

Obviously it would preferable to relocate the fitting.

Thanks for the quick reply gents , i could move the fitting but it would mean moving the other 5 too , to keep them looking inline , the fitting has free air all around apart from the joist ,

would i be able to swap like for like from halogen to LEDs , is guessing this is because LEDS give of less heat ?

A lot lot less, but reading the suggestions posted by others regarding covering the timber with some kind of heat barrier, it would be another solution.

Never thought of using products like that to protect joinst/timbers before.

I Forgot to mention that the spotlight is a 'open top' and is not enclosed (in the void) will this make a difference ?

 

[liambroad]

Would fitting a fire hood do the same thing ?

 

[cjp1]

I would probably fit a fire hood and leave well alone,
I have seen lots of 50w gu10s and mr16 fittings near touching joists and they have been fine, not what I would do nor recomend doing but if the holes are already cut and ceiling decorated you options are a bit limited.

The way I would look at the problem
Ask myself why should they be apart from the beams,conclusion,they can cook them and possibly cause a fire
Given that the damage has been done,the hole has been cut,the solution would be to make it so that heat damage will not occur
Led lamps or
I would insulate the beam with heat retardent material,a little bit of Welsh slate tacked on there should do the trick

On a further point,it would take some enormous heat source to set fire to the side of a beam
If the heat build up was that intense,the cable would likely melt and the light would go out before beam damage.or at least that would be my reckoning

How about getting 1 of those heat resistant pads that plumbers use when soldering near tiles etc and using that to deflect heat away from the joist. Maybe someones already mentioned that here.......

 

[liambroad]

Thanks for the tips guys i went with using the plumbers heat pad , only £3 from the wholesalers bit of a bargin me thinks
