PVC Ceiling Cladding and GU10 Halogens

[Strima]

Evening all,

Has anybody come across problems with GU10 halogens causing damage to PVC ceiling cladding? i.e. Yellowing of the finish, melting of the cladding etc?

I know this stuff is fire rated but can't seem to find much information on heat damage from lighting.

Was asked the question whilst down the wholesalers this afternoon and didn't have a firm answer. Bloke is looking at a bathroom refit and wanted to be certain that his lovely ceiling wouldn't land on his head whist in the shower...

Cheers all.

easiest solution....... LED..... simplesss.

It's down to the heat from the GU10 lamp heating up the metal casing...doesn't heat up enough to cause damage in most situation's but PVC cladding will basicaly melt/become brittle around the fitting over time.

As stated...LED...simplesss.

i have 4 35watt GU10's in plastic soffit. they are on PIR and so not on for any length of time. no sign of heat damage so far ( 8 months). going to fit LED as soon as i can get back earning.

Never had a problem with them but tended to put 35w in , but agree with Tel and Swicade now that Led's are an option Haler are the way to go.

As above LED simplleess.
The thing you are looking at is the surface temperature of the fitting whilst in use, generally if I remember those suitable for mounting on normally flammable surfaces must not reach a surface temperature above 65 deg C or it may be 85, and this is below the melting point of most PVC and so would not melt but may start to deform over time.

Cheers for the responses so far. I prefer to fit LEDs but there will be the odd one that wants 50W GU10's in and there's always the one that will just whack one in when the LED dies.

You can't with Haler, they have a dedicated fitting. As I said before I have never had a problem with them. they just show all the lines up in the cheap plastic.

The only other problem is the need to use downlights with spring loaded clips NOT the lever type clips because the PVC ceiling cladding is hollow and flimsy.

Lol I fitted a can type and when I let go of the spring it came straight through the $@@@@ cladding , you have to be soooooo careful lol.
