Why not use a heat mat for the heating and a way smaller light just for basking and viewing? Is it for snakes or lizzards?
thanks for that red-ink how exactly have you secured it to the roof ? just screws or do you use some sort of glue as well thanks again thomasMeanwhile
Here's some I prepared earlier.....

I'll post some photo's later tonight.
I have 5ft white melamine enclosure.
A ceramic heat light, 200W on a pulse proportional thermostat and a UVB light.
Been on for around 1.5 years.
I noticed last night the there are stains on the roof, on closer inspection, they are burns.
On even closer expection (with my head in the tank) I noticed the power cable is also discolured and looking old and worn, I'll be fixing it on the weekend. Though it can only be temporary as the same thing will eventually happen.
The cable comes thru the back wall and runs along the roof, not thru the roof.
The light fitting is fitted directly on the roof.
Like I said, I'll take some photo's and post tonight... though it wont be till later.
I can't be the only one with this problem or that's had this problem...
I figured if I got the bigger one, it wouldn't need to work as hard, therefore last longer.
remember that melamine is only plastic not good for heat stressAll good
No that's handy to know.
Still hard to believe the air around it is getting so hot. I know the surface tmep would be very hot, but I couldn't see it being hot enough to slowly burn the melamine. I would of thought it would be far enough from the globe.
Ahhh well.
That's exactly that floating light fitting I was trying to explain to you. They are the best
As a rule of thumb, you should only use a heat source of the MINIMUM wattage required to do the job. Building in a "safety margin" so the unit doesn't work so hard is asking for big trouble. If your thermostat fails (as they OFTEN do), a bigger than necessary heating unit will cause a very rapid elevation in temps, with dire consequences for your animals (first)... the enclosure (second)... your house (eventually, if you're not home)...
Radiant heat from these devices seems mild, but the buildup over time can be massive. I've seen tables burnt to charcoal from even 7w heat mats that were installed without the appropriate ventilation, Most particleboards have some sort of fire retardant qualities, but exposed to a constant high heat source, they will begin to smoulder and produce very toxic smoke. Once the particleboard or MDF has disintegrated above the fitting, it will drop from the top of the cage and who knows what it will heat next. But by then your animal/s will be very dead from smoke inhalation or heat stress.
Always remember that too much heat will kill your animals in minutes, but being too cool gives you weeks or months to sort things out.

Villaboard or Hardiflex are probably the commonest fibrecement brands, and both are readily available and very cheap.
