I came across these gu10 leds which claim to be as bright as 35w gu10

Lumens 110
Colour Temperature 3500 or 6000k
Life Rating 40000 hours
Size 50mm diameter * 63mm long
Wattage 2.3w
Running costs <1p/day
Product code GU10 LED-GU10-24SMD-WW
MR16 LED-GU10-24SMD-CWWW as a 35w halogen.

has anyone used them? They are £17 each so pretty expensive for a lightbulb. I,ve got about 40 gu10 in my house so probably costing me a fortune in electricity so would like to replace them.

Don’t waste your money on LED GU10 replacement lamps; the quality of light regardless of manufacturer is poor at best. With current technology LED’s are only really suitable for feature lighting and emergency lighting applications, not general lighting. Personally I would recommend just getting into the habit of switching lights off in rooms not occupied if your worried about the electricity bill. If you factor in the price of purchasing 40 LED lamps you could pay a fair bit off the electricity bill.

Not used those but do have some 1.5w LED's. I mix these 50/50 with standard GU10 35w which works for me and I guess gives me a 50% saving in theory. They are from B&Q 2 for £8.

I have also used Megaman gu10 11w which are surprisingly good for energy saving bulbs and are almost instant on. They also do a dimmable range which I have not tried yet, although a bit pricy unless someone is selling then on ebay.

Totally agree mate, in short LEDs are rubbish for anything but making something look pretty. Totally in practical!

Maybe in the future though........

My place had loads of GU10 50Watt bulbs and ending up replacing them with gu10 80 led bulbs from http://www.led-import.com/ they look fine but you just cant dim them. Oh and as there only 3W its cheaper to run and better for the environment.

are you using them to light a main room in the house or as ambient light?
the leds i have at the moment are used in my porch, i tried them in indoors and they look poor.

I've been wondering about these myself. I know searching the net, most opinion is that these are rubbish for general lighting, but have wondered if technology has improved, and there are new designs that are supposed to be higher powered, have more leds, better reflectors etc.

Many make bold claims about being as bright as a particular halogen, but the lumens figures contradict this.

e.g. the above claims to be as bright as a 35w GU10, and yet the lumens is 110, compared to a real 35w which is more like 600.


I would like to go more green on these, as everything else in my house (except a certain uplighter*) is energy saving stuff and perfectly fine light (all CFLs). The GU10s I've got though are kitchen lights and they need to be especially bright.

What about CFL GU10s though? Probably too slow to turn on I guess.


* - that uplighter is a whopping 300W halogen! It's very nice but I didn't think about the power when buying it. There's no real energy saving equivalent for the light it gives out, although it does include a dimmer but I'm not sure if dimming it actually saves energy.
