WHAT COMPONENTS OF A HALOGEN DOWNLIGHT CAN FAIL?1 2 V HAL O GE N GLOBEThese globes operate at around 300 degrees celsius so are vulnerable to blowingfrom inrush current, surges and duration of use. You can legally replace theseglobes yourself.L A MP HOLDER LEADS AND SOCKETThis is where the halogen globe plugs into - these can burn out from loosecontacts or from the heat of the globe. If these fail, you will need a licensedPerth electrician to repair.THE DO WN L I GHT T RANS FO R MERThis is what turns the electricity from 240V to 12V. Your lighting feed will behard-wired into this device and then wired to your globe from here using thelamp holder. If these fail, you will need a licensed electrician to repair.WHY HALOGEN DOWN LIGHT TRANSFORMERSARE NOT WORKINGThe main reason why a halogen down light is not working is because of the heatit is exposed to in the roof space. The halogen down light is a piece of electricalequipment that operates at a very high temperature and therefore is at a high riskof failure in all components. Some typical reasons why halogen down lighttransformers fail are:

I N C RE ASED TEMPE R AT U R E
The transformer is installed too close to the halogen down light globe which
increases it's normal operating temperature. The transformers need to have
adequate airflow to allow the device to regulate its own temperature.
E X CEEDE D O PE RATION T I ME
The transformer has exceeded its operation time. Every time you use your
halogen down light, you expand draw heat through the coils of the transformer
which causes expanding and contracting of the metals. Over time, they become
less efficient and eventually fail from the heat.
MOISTURE
Moisture entry into the coil which causes internal arcing. Any moisture will
increase the likelihood of the electricity jumping across from active to earth or
active to neutral. This is the same for any piece of electrical equipment.
I NS UL AT ION
Transformer and fitting covered by insulation. This is a very common problem
we see and a huge risk to you as a home owner as this is a leading cause of roof
fires in Australia.
HOW TO REPAIR A HALOGEN DOWN LIGHT
TRANSFORMER
You cannot repair a halogen down light transformer as when they fail, it is
usually from internal arcing due to the reasons about and therefore the
transformer will need to be replaced with a new one to fix the light fitting. It is
