If the transformer was designed to work with halogen lightbulbs then it may have an issue in providing the lower power supply that LED bulbs require. Each light has an Aurora transformer 20-60W/VA so I don’t think they will work with 8W equivalent LEDs. Halogen spotlights are a form of incandescent light bulb that use a tungsten filament and a mix of inert and halogen gases to produce light.

For example, a 40VA transformer can handle up to a 40-watt halogen light bulb, while a 10-60VA one can carry between 10 and 60 watts worth of bulbs. The actual wattage of the LED light bulb may vary, but the equivalent wattage must be the same as your current halogen bulbs.A warm white (3000K) light is very similar to a normal 20W halogen bulb and can be sufficiently bright.

We have found that some transformers are rated for use between 100W to 400W for example, so where 100W is fine for halogen (equates to 3x 35W halogen) this figure is not met with 8x 3W LED light bulbs (24W < 100W). I have over 100 potlights and thus far 8 have stoped working burnt out the connection, and 92 are still working without damage.I would advise replacing the whole spotlight to a waterproof (IP65) rated fitting with an integrated LED, which would eliminate this strobing problem plus give you confidence that you have a safe product to use. The natural energy-saving properties of LED light bulbs means that they can offer the same brightness of a halogen equivalent, but using only a fraction of the power.

Some caravan and motor home light fittings including downlights will use a 5 to 20 Watt G4 Pin type Halogen bulb similar to the image on the left, with the pins going into the side or the back of the fitting. You may run into problems with this transformer, as it is designed for use with Halogen light bulbs and therefore has a wattage range of 20W to 60W. For example, if you have one 35W halogen installed in your kitchen, ensure you swap it for 35W equivalent LED.

All you have to do to swap your old bulbs out is remove them from the light fixture and fit the new, shiny bulbs in their place. The majority of bulbs are for use with mains circuits, except for ‘low voltage’ light bulbs, which must be used with a compatible transformer ( see below). The warm light of halogen bulbs is within reach thanks to the fact that LEDs can handle all colors of white light.

First thing first, this sounds like a dangerous situation and a serious fire risk – I would advise you get an electrician to test those remaining fittings immediately. The European Commission directive in September 2016 banned the manufacture of this type of power-hungry spotlights. I am currently looking to replace the halogen MR16’s in my daughters room which are currently 12v 50w on individual transformers. We’ve finished our guide off below with a quick ‘cheat sheet’ to help you remember all the technical terms discussed above. I have these transformers which have been attached since 2000, see photo below, can you please advise if I have made a mistake in choosing the correct bulbs for the job?When talking about the equivalent, does this mean each bulb can only be a maximum of equivalent 60W overall (I. This is only getting more complicated as LED technology gets ever more energy-efficient, but as long as you remember to look for the equivalent wattage, you will find the right LED spotlights.
