2.0 out of 5 stars
Not as good as other GU10 lights, 29 Nov 2013
Customer review from the Amazon Vine Programme (What's this?)
I've reviewed a fair few LED low watted GU10 lights and I'm very much a fan of the technology. I am afraid this is not one of my favourites. The colour does not seem as bright as many Philips models and the design does not look as smart. Search for my Philips GU0 which gIves far a more much more comprehensive description. I'd not recommend this specific model. I don't; like the white colour or the limited light area exposed.
Just two stars I'm afraid.
I thought it might be useful to copy my review of a Philips bulb here to capture the science behind the figures banded around so here you go! Most buyers don't seem to want to know the warm whites, the beam focus etc but I can live with negative votes! I've removed my starring of this particular bulb for impartiality.

Customer review from the Amazon Vine Programme
I seem over the last few weeks to have found out more about light bulbs than perhaps I ever wanted to know! Nonetheless it's worth a bit of research when bulbs are this expensive and I've been gradually replacing suitable bulbs at home with these. The bulbs are designed to replace 50w halogen spotlights - coded GU10 - which are commonly embedded into ceilings in kitchens and bathrooms or form part of spotlight installations. They have rounded power fittings not to be confused with the needle-like connections of 35w halogen bulbs. These Philips bulbs use the latest technology - LEDs (light emitting diodes) - which are the next generation of lighting replacing florescent tube bulbs which have, in turn, replaced the original incandescent bulbs.
The bulbs form part of Philips 2013 light bulb release (yes, there are annual releases of light bulbs together with glossy brochures about them). They are available in six different flavours - there are three choices of colour warmth - 2700k very warm white, 3000k warm white and 4000k cool white. Each has two choices of beam focus, 40 degrees for more general use, say in a kitchen ceiling, and 25 degrees for a more concentrated spot-light effect. All use 6 watts (as opposed to 50 watts for a standard halogen bulb) and as far as I can tell output the same amount of light as halogen bulbs. In theory the `very warm white' 2700k bulb reflects the light colour from a standard halogen bulb. I find it a little too warm and prefer the 3000k 'warm white' for most settings. The 4000k `cool white' produce a noticeably whiter-white.
The headlines for these bulbs is that they use just 6 watts so a near 90% drop in power consumption. As most halogen bulbs tend to be installed as groups there's a chance for big power savings - 4 halogen bulbs use 200w which can be reduced to 24w. You could almost leave the bulbs on continuously they use so little power. However, another headline is that they are very expensive and Amazon is not the cheapest place to buy them at the time of writing this review. They are guaranteed by Philips for five years and are projected to last for 15 years or 40,000 to 50,000 hours. They also fill a gap in the market in that florescent bulbs are not available for halogen GU10 fittings. They are exactly the same dimensions as a halogen GU10 bulb so if you have a halogen bulb of this type you can replace it with these bulbs. You should note that the actual surface area of the bulb is smaller with a silver indented surround to the bulb itself. This does not impact on light output and looks OK.
Good news with the 2013 range is that the bulbs are dimable (unlike almost all florescent bulbs), they have a rather good silver finish compared to the white of last year, and have a longer life. The bad news is they a bit more costly and use 1 watt more power. Last year's used 5 watts rather than 6.
So far I've replaced three bathroom halogen bulbs with 40 degree cool white Philips LEDs. I like the white light in this environment. I've changed four kitchen halogen bulbs with the warm white 40 degree bulbs and four dining room lights with the very warm white (2700k) bulbs again at 40 degrees.
For most environments, particularly if you want the lighting to remain as it was with halogen bulbs I'd go for the 3000k warm white 40 degree bulb or 25 degree for a spot-light effect. Perhaps for highlighting cut glass, or chrome, using a 25 degree spotlight, or in a bathroom or more clinical setting 4000k at 40 degrees is better but you will notice a colour difference.
This particular bulb, to decode Philips' numbers, is a 6 watt very warm white (2700k) bulb with a 40 degree light dispersal.
