How hot does a halogen globe actually burn?
Halogen, General Technical Stuff September 1st, 2009Hi,
We have just moved into a house with what seems like hundreds or MR16 lights (all put in around eight years ago), I will remove half of them (pitty the poor soul who’ll be patching the plaster on the ceiling) as these two rooms already have incandecent lighting, this should save power and heat.
The other half of the MR16 lighting is under a flat tine roof which was assembled TIN/SilverInsulation/Insulation Bats/MR16 Down lights, at points the Bats were touching the MR16 lights, I have replaced all MR16 globes with 20w ones I purchased from you and tried at best to remove the Bats from around the MR16 lights but being at flat tine roof at this point it is quite hard.
My question is this, how hot do the 20w globes get as I understand the 50w are in excess of 260c so I estimate the heat to be around 104c reducing the fire hazard considerably (I hope). Also, what is the power consumption of the transformers and do they represent a fire risk?
Regards,

Hi Chris
The % reduction in heat should be proportionate to the wattage reduction
The lamp burning temperature really depends on the ambient temperature, air flow, the fitting design and the length of time the lamps are on
The direct comparison between 20W lamps and 50 watt lamps should be 60% but as there is no data available the only way of truly checking this would be with a thermometer
We now have flexible heat guards which may or may not suit the application but can be installed through the hole
If you are looking for alternatives to the halogens depending on the hole size these may be a great alternative. I am a fan of these fittings, so much so I am fitting these style in my house at the moment http://lightingpro.com.au/catalog/index.php?cPath=62_117
Please let me know if you require more info
