Very similar by the looks of it. I admit to feeling good about saving 94w every time I turn them on.

I think I have 10, so yeah, it's a pretty substantial saving - 500W down to 50W.
Also, my hair has stopped catching fire.
I bought some el cheapo 4W ones from ebay, they're perfect for my usage and not one blown yet (B&Q ones I got, one died after a month) Are the branded ones that much better? Think I paid about £4 a bulb or something like that. They are 4 individual LEDs instead of the multiple little ones?
I did buy bright white and it made the kitchen look really strange so i popped them in the bathroom instead.
Power saving wise I've gone from 4*20W + 8*35W down to 12*4W (ie 360W > 48W) coupled with the fact my wife leaves all the lights on in the house all the damn time I figure they've paid for themselves pretty quickly!
Led hut is offering a 15% discount and a free torch for orders this weekend. The code is RUGBY15.
The wife wouldn't let me change all of them in the kitchen. She has Luddite tendencies that nicely counterbalance my 'OOOoh Shiney' response.
The ones people have posted are either power LEDs or SMD, I was referring to the ones mentioned by phil4, similar to the first picture here: http://www.ebay.co.uk/itm/GU10-20-38...item2320ce14da
Power LEDs really need a diffuser of some sort, they're a very intense 'point' light source so are very uncomfortable, possibly even dangerous, to view out of the corner of your eye. SMD LEDs are often designed to give a more diffused light. Both types are generally designed with heat dissipation in mind, and come mounted to heatsinks - an incan might be happy to bake all day, but LEDs quickly degrade at high temperatures and tend to send most of the heat back into the device, rather than radiate it along with the light like incans do. 5mm LEDs generally aren't designed with area lighting in mind, are fairly power/thermally limited and often use poor/cheap phosphors.
Light quality is a largely subjective thing, but cheap LEDs, regardless of claimed colour temperature, tend to have very poor CRI. Incans have a fairly linear ramp in wavelength output from red being highest, down to blues having a lower power. 'White' LEDs are actually blue LEDs coated with a phosphor. Cheap phosphors have very spiky outputs, peaking around blue and green and lacking a lot of red. Better quality ones have smoother outputs allowing colours to look more natural and are less fatiguing on the eyes. Fluorescents are also prone to poor quality phosphors. There's a reason supermarkets/restaurants have incan/halogen lamps illuminating food displays - it just doesn't look very appetising when it's illuminated by the low CRI halide lamps. Ever noticed how that chilli looks great under the halogens in the kitchen, but looks a bit grey on the table illuminated by CFL?
Yep. As I said, these are still bluer than I'd like. But when mixed in with the halogens it's acceptable. I'm still waiting for a true warm light that I can use anywhere. I was hoping that the newer stuff would be better.
I have some high-CRI LEDs from Nichia (don't think I've tried the ones from Cree yet) and they are pretty good, far better than we've come to accept from CFL IMO.
I'm not too keen on the LED Hut lights as they're not very bright. I think the Homewatt ones are better with much more lumens meaning more light.
As for the article on CREE LEDS, it seems they are remarkably good value given price, lumens and wattage. I'd probably buy one for the bathroom should it be release in the UK.
I was planning to get an LED hut one to try, but thought I'd ask about CRI first as that little chat box opened asking if I needed any information. The assistant asked if they could get back to me, so I provided an email address. I'm still waiting.
Actually they look exactly the same. Only homewatt is cheaper ! Thanks for that.Quote:

£30 a bulb and i need 11 for the Kitchen...
maybe if that was a tenner i would do the lot.
Perhaps looking at your electric bill may persuade to switch sooner!Quote:

Okay, in that case I'll take my comment back since you have CCFLs but my comment is valid for people still using halogens.Quote:
