As close to a halogen GU10 as you'll get,
This review is from: Philips Master GU10 6-50 Watt LED 2700 K 25D MV Spot Light, Warm White (Kitchen & Home)
Customer review from the Amazon Vine Programme (What's this?)
Running a few 35W and 50W GU10s in our household I can't help but feel guilty every time a bank of them is turned on. I had always hoped that I could replace them with efficient varieties, but have so far been disappointed by the low output of the first generation LED GU10s and the bulky size and slow startup time of the compact fluorescent variety.
I have previously tried a Philips 'High Power' GU10 a couple of years ago that I bought locally for about £15. It was a lot brighter than previous efforts, but although it claimed to be 'warm white', it was closer to pink if you ask me.
Plugging this rather pricey new-generation Philips in, I was expecting much the same as before. I was pleasantly surprised however, to find that the colour of the light output is closer to a standard 50W halogen GU10 than any LED bulb I have previously come across. I personally don't favour the 3000K 'Cool White' when used in the home, as it creates a sort of surreal and otherworldly environment not suited to a living space.
I would say that the beam is a little bit narrower than a standard bulb, but not massively so.
Ultimately, I believe this is the ideal replacement for a halogen GU10 of the 50W variety. It says it is dimmable although I am unable to test that function. The 40,000 hour quoted operating life is better than lower-priced bulbs, but this will be a difficult claim to comment on at this stage.
The only thing standing against this bulb at present is the price. At c. £23.00 (at time of review) it still represents a huge outlay for a bulb. Regular GU10s can be had for a pound a throw these days, so you'd have to be deadly serious about saving energy to warrant spending this kind of money. As with all things technical though, they will come down in price.
