Which GU10 LED?
GU10 lamps are the most popular choice of cap type in the UK. GU10s became the #1 choice for downlight installations in the late nineties, taking over from the MR16 (GU5.3) cap. The main reason for this was because they're mains voltage and don't require a transformer unlike the MR16 (GU5.3) which operates on 12 volts.
Because it doesn't require a transformer, it's more cost effect and easier to install. Many consumers are converting their existing low voltage MR16 downlights into GU10 so they don't have to deal with the possibility of the transformer not being compatible. If you're converting to LED and also have to upgrade the transformer (AC to AC) to an LED driver (AC to DC) it's going to end up cost much more and will require some rewiring. By the time you'd done this you could have fitted a brand new integrated LED downlight.
As the demand increases for more a more energy efficient alternative to halogen, so does the variations from different manufactures all claiming to be the best. Halogen technology should be only used for heating, not lighting. The amount of heat a 50 watt halogen produces is ridiculous and a total waste of energy.
We've compiled a short buyers guide that compares our best GU10 LEDs, although we do offer many others, the ones we've selected offer key selling features such as brightness, dimming performance, reliability and value.
