Energy saving bulbs GU10 for kitchen & bathroom

savemoney

We have the gu10 megaman in kids bedroom for 3 years now and its great. We also megaman candles in living room/dining room for over 3 years now with no problems. They do take slightly longer than normal gu10 to warm up and give slightly blue clinical light

Thanks for feedback, seems LEDs have improved. I am thinking of trying these http://www.tlc-direct.co.uk/Products/LTGU9W.html. No need to change fittings

Question which type of light is best for a kitchen - Daylight White 5300-5700k, and for a bathroom Warm White - 2500-2900K.

Depends on room colours, ie, walls and units and personal preference. I think I prefer Cool White in bathroom and kitchen, and the Warm White in dining room and living room. All down to what you prefer though.

CREE LEDs with a 70 deg. arch (or 120 deg. if you can find them). Much better than the ones with 80 individual LEDs on as these have a very narrow beam angle.

I use cool whites in my living room, these have the same colour spectrum as sunlight through a window.
Cost £25 each, but have worked-out that as they are on for 9 hours a day they will pay for themselves in under 16 months.

Incorrect. Most 80 LED bulbs have 120 degree angle of light, but as with most LED bulbs, there is no one answer fits all for the different bulbs. I have seen and used many 60 LED and 80 LED bulbs that have given a full 120 degree angle of light.

How can the latest LED bulbs be as bright as a 50W GU10 which produces about 900 lumen. The LEDs seen to to produce 300-400 lumen. Dont quite understand this measuremnt.

Because Lumens isn't a true brightness of the overall brightness of the bulb. It is all down to angle of light...

Have a good search on Google on how lumens are calculated, will make more sense that anything I can type here!

Philips LED spot Perfect Fit MV GU10 about £14 and claimed to last 25 years !!

Fitted some to replace halogens in my house to reduce the electricity bill !

I've heard good things about the Philips bulb, what do you think of them?

That's because they're not as bright. You can try to 'fake' the equivalence by narrowing the beam angle on an LED so that when the light hits the floor it looks as bright as a halgoen GU10, but in reality it isn't.

If you want some unbiased analysis see here:

..and take a read of the Special Summary report (April 2011) where they tested MR16s (closest they have to GU10s in the U.S).

I see Groupon are offering 3 LED bulbs for the "bargain" price of £21

This is a !!!!-take, surely?! Have you seen the original price? 3 for £75?!?
Groupon's so-called deal is more than you'd pay in Argos (£9.99 for 2).

I paid £15.78 inc postage for 3x60 LED GU10 from Phoenix Direct in November last year and I'm more than happy with them.

On ebay, you can get 10 slightly lower wattage for £18 from the UK, or if you want to risk China, you can get 10x50w equiv for £36. Even UltraLEDs (very good quality but relatively expensive) work out better.

Wondering how this is a "deal"?!
