    GU10 LED Bulbs

    We have lots of these 50W GU10 Halogen spots in our house. Thinking of energy saving and replacing with LED bulbs. Bought a couple from B+Q with 20 LEDs. Give off a blue/white light but not very bright. Searching online I see you can get ones with 60 LEDs, called superbright.

    Anybody have experience with these bulbs and where to buy them from? Will they be bright enough to replace a single 50W bulb in our bathroom?

    We've got 2 of the 60 LED Gu10, one cool white and one warm white. The ones your linking too suggest they are cool white.

    No they aren't bright enough to replace 50w halogens!

    They are about 35watts at a guess, I can't measure them accurately but that seems reasonable. They are bright just not 50w halogen bright, I got mine off ebay where you'll find many. They've lasted about 6 months so far and still operate as expected. Instant on, don't get warm and use little power. We had a 4 x GU10 halogen on a bar in the kitchen, I've replace 2 with the 60 LED GU10, 1 with a Megaman CFL GU10 (slow warm up but 50w equivalent easily) and one 50w halogen. So we get instant bright light, overall power usage is down from 200w to 66w. Its a good compromise imo though of course I'd like to go all LED they aren't as bright yet and they are more expensive.

    My Mum got 4 to replace hers in one unit and they are awful. Only give off downward light like a dull torch. just a gimmick as rip-off prices at the mo IMHO.

    Doing some more research, appears the Megaman 7W,9W, 11W CFL GU10s are quite good, brighter and better quality light than the LEDs.

    Best price I can find so far for 10 7W Megaman BR707i is £66.86.

    Anybody seen cheaper?

    Was looking at changing to these myself but reading your posts make me think it would be better to hang back fora while - thanks.

    The Megaman CFL GU10 are excellent but they aren't cheap and they are slow to warm up. If you can live with that then they are a good replacements.

    The 60 LED GU10 are expensive, build quality will vary off ebay, only about 35watts and you have to make sure you order the right colour. As I said with the mix of Megaman and existing halogen we've reduced the power usage but get the best of both worlds. I wouldn't go all LED yet until they are brighter.

    I might buy one or two megamans off Ebay and see what they are like.

    just got 3 off ebay GU10 LED LOW ENERGY LIGHT BULB WHITE , they only have 18icd's but should be fine in the bathroom. i have to get 4 for the kitchen now to replace the 50watts ones , which would be best.

    See a lot of talk about the LED60 lamps
    Couple of points really

    Led gu10 60 are not suitable for bathrooms or high humidity areas.

    This type of bulb give of around 35w power output the best ones give 350-400 lux

    The cheaper ones are around 60mm dia not 50mm.
    I have found a lot of bulbs on the market (ebay) are cheap chinese imports with low light and short lift some even around 15000hrs a good one costing from 8.00 upwards will last 35000hrs

    One other thing to watch is that over the life of the bulb the light will dim. Do not get me wrong they look good and are good but are not a like for like on a 35/50w gu10 standard halogen or xeon

    I also believe these are not suitable for any kind of dimmer switch. best off waiting until prices come down. remember that low energy and halogens were £4-5 each when first introduced. Now they're 50p each.

    Is it possible to use these LED lights on dimmer switches,If so which ones

    I have a 40/250w light range on the dimmer switch.

    At the moment i'm using 3x 50w and 2x35w,

    When i used 5x50w and one bulb blowed and it killed the dimmer switch,so i had to replace the switch and the bulbs to run within the switches wattage range.
    So what i'm after is the same as you Guy's,Bright light but dimmable,and low enegy usage.

    Any advise please

    Since posting this thread I have now upgraded 10 of my GU10 spots with Megaman 11W GU10 bulbs with 15,000hrs life. They take a bit of time to warm up but give a good brightness , must be close to a 50W halogen. They cost me £8.20 each, so not cheap. Hoping it will have an impact on my £65/month electricity bill. They are longer than the standard halogen bulb so will stick out more.

    We don't have dimmer switches but I understand there are Megaman CFL GU10 bulbs that can be dimmed.

    these megaman 11w gu10's work out at £6.50 each inclusive of vat and delivery

    @spudgun I notice your link has the warm white option whereas my link gives a choice of warm or cool. Do you think the lights you have bought would benefit from being bluer perhaps which I guess is what the cool white option would give?

    I like the warm white colour, since posting this thread I found them cheaper on Ebay, buying 10 for £70 delivered, your link looks good though, haven't gone through to checkout to see what they would cost for 10. £6.50 i presume you meant to say? I'm sure the price must have dropped since i searched in March.

    Have you noticed a reduction in your energy bill?
