MR16s also run on just 12 volts, while GU10 spotlights have more flexibility and can run at 240 volts (which is more common in households).

Bulbs that operate on a lower voltage than 230-240V must be used with a compatible transformer when installing on UK mains circuits.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. Philips Hue MR16 smart bulbs are as bright as a 35 W halogen bulb, so they're the perfect smart upgrade from conventional bulbs (and with colour light, they’re even more of an upgrade).

GU10 LEDs run off 240v so no transformer needed, but you will have to change the holder if yours are currently 12V.The first thing is to determine the type of spotlight you have in your home – you can use our diagram below to determine which one you have. We’ve got quite a lot of these throughout the house and if possible I’d like to avoid replacing these (due to the cost) with an LED driver equivalent. I guess an alternative would be to fit new GU10 lamp holders with LED bulbs and ditch the transformers.

The LEDs are too far from the transformer, resulting in voltage drop (the maximum distance is about 1. 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). Not sure what you mean by splitter, if more than 1 light is run off a single output of the transformer you may well overload it. As a result MR16 bulbs need an external transformer to convert the buildings main 240 volts mains supply to the 12 volts required to run the bulbs. Unavailble in the uk (for I think safety reasons) as the pins on mr16 could be exposed whilst live and would be deemed dangerous.The other way just to rewire (remove the transformer for the Halogen lamps and using the mains supply side connect the GU10 (two thick pins ) socket. This is the fundamental difference between GU10 and MR16 bulbs and the most important thing to consider when upgrading your home lighting. So my question is, should I have a new fuse fitted to my fuse board supplying the lighting in my home, ie 5amp, or am I totally confusing things? I've been reading reviews of these replacement LED bulbs and I can see some of the negative reviews say it's flickering which is due to transformer, if I'm not wrong?

We also offer a Shower Rated downlight fitting which (surprisingly) are perfect for bathrooms as they guard against water entry. I have doubled checked that I have wired the new transformer correctly but the bulb flickers with very little light. The LED light bulbs we sell operate on a UK standard 240V AC, and the light bulbs have a built-in transformer to change this 240V to the LED required voltage. Hi Rakesh, So that specific transformer is rated to work between 50W and 150W – this means that the minimum load that needs to be used is 50W, and the maximum load is 150W.I am currently looking to replace the halogen MR16’s in my daughters room which are currently 12v 50w on individual transformers. I had transformers on all my downlights when I moved in, several transformers had gone, slowly I replaced them all with 240V LEDs (like these: https://www. The European Commission directive in September 2016 banned the manufacture of this type of power-hungry spotlights. Can you please help me I used to have 6 Halogen Bulbs on one circuit then changed to 6 LEDS which worked fine but slowly one by one the transformers have packed in so I got some used ones and now the LEDS flicker. What I want to ask is – what is the likelihood of my having one of the older “wire-wound” type of transformers in this shower room as opposed to one of the newer low-voltage electronic ones.
