Energy saving GU10's

Lee_JTD

Just bought a shed load (44) of energy saving fitments (Hispec) that include a 'daylight' GU10 11w 6400k lamp.

Now in hindsight maybe I should have gone to check ONE out before embarking on my mission to save the planet and become an eco warrior!

The light in the living room where there are 12 of these beauties is moon like, with this blue haze. What can I do? How can I replace them?

I have ordered 6 14w Megamans Low Energy Spotlight GU10 14W 830 15K Hr Megaman 14 Watt on a trial basis (new out so am waiting a while for them), I am hoping these give off the brightness and warmth needed in the living room. The fitments are too long for a normal halogen and anyway they only have a maximum wattage of 11W (hoping an extra 3 watts won't matter).

If these don't cut it can anyone out there advise me on where I go from here?

standard halogen GU10 bulbs are generally 38-42 degrees, so they are closer to the original spec you are looking at replacing.

Any results yet to report for the new 14W Megaman GU10 MM14152 ?

Hi

Just my two pennies - I'm really hoping that this is the answer to lighting...

Have a fair number of cool white and warm white GU10 LED bulbs around the house now, the oldest have been in place for a coulpe of years with no failures.  Reliability is excellent compared with the compact fluorescent GU10s - I found the CFLs didn't last long, especially when switched on and off throughout the evening, but that's probably not much of a surprise.  The worst lasted about a month, others followed quickly after.  Perhaps reliability is better now but I've replaced them all with LED lamps.

The most recent LED lamps I've bought are 3w single LEDs for around a tenner each and they put out a reasonable amount of light but still nowhere near a 30W halogen. Cool white is brighter than warm white (and looks great lighting a black slate floor!) however the beam angle is pretty narrow so casts a pool of light on the floor.  Mine stay on most of the evening but are supplemented with cool white fluorescent uplighters when we are using the room.

They come from Kymanledtex.com - suppliers of eco lights and products though have to be bought via e-bay but I've had no trouble in the past...

I have recently installed an LED strip light from the same company which belts out a fair amount of light for 8 watts but its not particularly attractive - I just wanted to see what it was like!

One tip: some LED replacement bulbs do not fit into some fittings - I've had to file the downlight holders before to get the body of a bulb to fit and also if the bulbs are held in by a spring clip, the lip of LED bulbs can be a bit thicker than standard so that needs some work too.

The technology is advancing but isn't quite there yet; surely it cant be long, the energy saving potential is huge...

Thanks all

We have also had a problem finding LED 50w equivalent gu10 bulbs.

We finally settled for CFL versions and even found a 30w equiv bulb that was the same size as a standard halogen bulb.

If any one has any led high light output GU10 bulbs that are as good and as small as a halogen 50w please post back.

Just bought and installed one of these to test

Zenigata - all purpose power LED

It's pretty good, but perhaps I should have done for the medium beam version as it does not seem as bright as a 50W halogen - but certainly closer than any other.

The savings of LED have moved me to install Zenigata 4W LED GU10 Bulbs. They might be top end on price but I know the savings will come.

Wow, these LED GU10's are a bit pricey!

I fancy changing the Halogens in my kitchen but don't really want to spend several hundred quid!

I found these: GU10 78 LED Home Studio Spot Light Lamp Bulb Spotlight

and whilst I'm sure they're not as good as the ones mentioned in this thread they are much cheaper, but are they worth buying?

In my opinion, I wouldn't touch these types of LED bulbs. Based on similar designs sold at B&Q, they have very poor light quality, poor spread and don't last very long. They give LED bulbs a bad name.

If you think the other LED are more expensive, calculate how much you are paying to run them and they will look rather cheap overall compared to 'cheap' halogen bulbs!

Interested in the Zenigata GU10s.

Anyone here used them?

If so how would you compare

(i) Brightness compared with 50W Halogen

(ii) Spread of beam compared with 50W Halogen

Which colour did you go for, White or Warm?

@robhowell

Just read your comment - what do you mean by medium beam version - I can only see two versions White or Warm.


Another Question

Ignorring the wattage as you can't directly compare that, I notice that the Zenigata is 200 Lumens but the Halogens are 500 Lumens.

How on earth can they be comparable given that one gives out 2.5x the light of the other?

Cheers,
