Product Information

It will save you money. MR16s are generally more expensive and their unreliable nature means they’re more likely to need replacing. Now that you have successfully identified your lamp, you have two options. If it is a GU10, you can simply replace it with a LED GU10 equivalent. However, if this is an MR16 then we strongly advise you make the switch over to GU10. You don’t always need to change the full fitting when swapping MR16 to GU10. My kitchen had the loose fly lead connections in the ceiling downlights. I rewired these to GU10’s mains and the old ceiling fitting still held the new GU10’s. You would not be able to do this on rigid fittings though! You can now get dimmable G4’s in 220VAC & 12VDC. This asks the question… is its best to swap the driver and use 12V LED’s or by-pass the original transformer and use 220V LED’s?

I know that GU10 LED 220V on a dimmer they should be sold as dimmable, but if you use MR16 12V with a dimmable driver, are 12V LED bulbs already dimmable and OK for say 3-12V?I have 4 x G5.3 MR16 compatible lights in my bathroom all LED around 4 watt each and I see no reason to change them, there are in pods so aimed as areas I want lighting, and the pods are not really suitable for low voltage (230 vac) so using the extra low voltage (12 vac) units.

Another point worth noting… many spots produce ‘torch beams’ dark/light areas that are awful in kitchens. I’ve found that the smd LED versions give much better light spread.The first thing you need to do is determine the existing type of transformer you have in your MR16 circuit. This will most likely be situated up in the roof above the light fittings – now in some circuits there is one transformer, but sometimes every individual light fitting has its own transformer. They tend to come in two varieties; the first is the older wire-wound magnetic transformers and the second is the newer electronic low-voltage transformer. Both work by stepping down the mains voltage (240v) to 12 volts, which allows the bulbs to function. We would always recommend using a qualified electrician, but if you are confident with basic electrical work then you may choose to do this yourself. This video shows you how it’s done. You will need a GU10 lampholder (the fitting that sits in the recess of your ceiling) to install your new GU10 bulbs. It will give you more choice in your lighting options, including smooth dimming. LED MR16’s dimming systems can be very unreliable while GU10s offer excellent quality of lighting.
