Energy Saving GU10

[Pimpster]

Hello all,

Does anyone have any recommendation when looking for an Energy Saving GU10 bulb? There are so many to select from, and they also vary in length.

Our study has 10 x GU10 spot lights in the ceiling and currently 50w bulb in each. So am looking for a drastic reduction in cost and heat!!

Thanks

(Forgot to mention, not looking for LED)

The 'flourescent' style bulbs that you seem to be refering too do give out good amount of light but they take time to warm up (30ish seconds) and they are longer than standard GU10's. This can make it difficult to fit into fittings (even 'open' style ones).

The lower wattage ones are shorter. Toolstation have a few to choose from.

Personally, I'd get one 7W bulb and try it - for fitting and for light out put / start up. If it's fine then replace them all. If start up is an issue then you may want to try fitting 35W bulbs in half the fittings and then 7W in the rest.

I use a mix of LED and flourescent style low energy bulbs.

Finally, consider getting lamp(s) to add extra light. You can fit low wattage bulbs in these and still be using a lot less electricity.

Why not LED out of interest?

I bought these are they are as good as normal GU10, if pricey.

There is no such thing. Well there wont be when the "subsidy" is removed which is very soon i believe.

These GU10 bulbs are probably the best LED bulbs available on the market today! They feature 20 individual SMD (surface mount device) LED's with a clear glass cover which produce a light output comparable to 50 watt halogens bulbs.

Lies. The cheapest 50W mains halogen puts out about 500 lumens so the simplyLED products 'claimed' output is only 3/5s of that. Low voltage 50W halogen can put out over 700 so how this company can make those claims is beyond me!

CPC have got some on offer @ £1.88ea, I've got some in my downstairs bog, come on bright much quicker than any others and have been fine. One of the expensive ones it replaced went up in smoke & burnt all the casing after only 2 months!!

Maybe so, but I replaced all 11 Kitchen ones and haven't noticed a difference.

Got a link? I can't find any near that price.

Thanks.

I have recently tested 4 different LED MR16's. The only one that came close enough to a 50W Halogen was a 3x2W Cree

Some that were advertised as "40-50w equivalent" are absolutely pathetic

I thought I'd continue with this thread...

There's currently a Groupon deal for 4W GU10 LEDs that makes them under a fiver each:

We're thinking of getting 30 or so of them to replace all the existing halogens around our house. They look a similar design to those mentioned above; has anyone ever used these particular ones?

I've had several different types of power saving bulbs (usually standard bayonet fitting) and every one of them has generated excessive heat around the base, resulting in fracture of the lamp fitting.

I've also had several fail prematurely (compared to the predicted lifespan stated on the pack).

I'm not convinced that they are a huge step forward when compared to conventional incandescent lighting.

In fact, This (somewhat lengthy) article makes for interesting reading.

I have 40+ Megaman's. They are dimmable on the switch, click once to dim and you can drop them to 3w each. Take a while to warm up, I paid a tenner off ebay to include the spotlight which is fire rated.

I have some by a company called alpha, I think they're single bulb 1.7 watts.. I have 12 of them set in an area of 8ft by 15ft in two groups.

With four on you could eat by them but they don't light the whole room, with 8 on you have a nice not too bright room. With all 12 on it's like having a normal bulb.
