Changing transformer on downlights

I assume that you have tested the lamps and they are okay. Assuming one transformer is controlling each bank of three lamps then it will be behind one of the light units. Before purchasing the new light transformer , compare it with the old one to ensure that it is exactly the same model. When the transformer is not designed for the light that you are working on, it will not work properly, if it works at all.


Otherwise they may need to replace all of your. This involves disconnecting the transformer and some re-wiring which should be done by a qualified electrician.

This option opens up a whole new world of opportuni. Install brand new downlights. In other cases, you need to replace the transformer with an LED driver. Disconnect the transformer if you need to replace it.


MRand MRbulbs use volts of power, so in most cases, they fall below the minimum load for a transformer. If this is the case, unscrew the posts holding the black wires in place to disconnect the transformer , then unscrew the wires that attach the bulb fitting to the transformer. A downlight transformer changes the input voltage, usually from the ring mains (UK 2volts) to, typically, volts.


The bulbs in downlights use a low voltage input.

Extra-low voltage (ELV) downlighters are often described as low voltage on product packaging. Halogen down lights now require shrouds to be fitted if there is insulation present, and the better ones will incorporate a bracket that keeps the transformer high and clear of the insulation. Read reviews and check our best-sellers.


Shop today at TLC Electrical! Indee the ferromagnetic transformer uses an extra five watts more than the electronic transformer with or without the globe’s load. While that doesn’t sound like much, it’s not uncommon to find or more downlights in a home.


I had to replace downlights earlier with led fittings and they were a right pig to get out without the springs damaging the ceiling, especially as this one was double boarded. Make sure the hole size of the downlight is large enough and the ceiling void spacious enough for the transformer and connection to be installe transformers do need plenty of ventilation, so avoid thermal insulation. The first step in changing over your halogens to LEDs, is understanding how your existing lighting system works. Do I Have Volt MR1 or 2Volt GUlight fittings?


Most halogen installations in Australia have either volt MRlamps with a transformer tucked away in the ceiling, or 2volt GUtype lamps. Varilight low voltage transformers that are available in a choice of wattage types ranging from watt to 2watt. The watt version can be used to power MRLEDs. V bulbs you will need to replace the transformer with a special LED driver. Order online at Downlights.


There will be mains cables connected to the downlights that are to be followed by another this is the carry the voltage to the next downlight in the circuit. Step 4: The LED Transformer can be put through the hole in the ceiling and set into place, the LED Downlight can then be fitted. The safety concern is in the mains wiring and keeping the fitting the same style as is already there, i.

Downlights and recessed spotlights are now becoming increasingly popular. Fitting these lamps is not too difficult and they can often make a room look very smart. These types of lights are available in mains voltage 240v or Low voltage (normally 12v) the low voltage ones will require a transformer and you may need several transformers depending on the total amount of lamps on the circuit. Replacing your existing 12VAC transformers in addition to your downlights can be costly and inconvenient, making it important that replacement LED downlights work well with your existing installation. I have Halogen downlights in my kitchen ceiling and one has stopped working.


I took a bulb I knew to be working and tried that and it didn't work. I changed the bulb and still no joy.
