Finally!

Will probably pick a few up when they arrive on the market.

Looks good. would have to order 1 to test the light quality before I commited though.

[watercooled]

Yeah I was thinking that, but I've used some of Cree's high-CRI LEDs and find them OK, certainly better than CFLs.

Have a look at these

(I've moved this to a more appropriate forum)

Cheers, I wasn't really sure what section to post in TBH.

They do look interesting, and seem to be well-received by customers, going by the on-site reviews. Still, they don't seem to be branded, and I wonder what light quality and longevity are like?

I've got two in my kitchen. They've been there for about a year.
The light is still bluer than tungsten (even tho warm white) but fine for kitchen or bathroom. They may have changed the light since. Want a pic side by side with Std GU10 ?

[watercooled]

That would be great if you don't mind!

Been thinking about getting some LED lighting myself for a while, but the ones I've seen have been either very expensive (Phillips) or terrible.

As for CFL, they seem to be either dim or give out a ton of poor quality light.

I've found the LED Hut stuff to be very good. Just bought a torch for £1.69 !
Pic below. The LEDs are on the left. Whilst they appear much brighter to look at, the light thrown on the floor (as it were) is very similar in output to the GU10s.
I've uploaded this at max res, but it's only a phone !

Cheers, that looks a lot better than I expected TBH, might pick a few up.

I've been using GU10 LEDs for ages, and they really are impressive. Can't see it being long until they've totally taken over from traditional energy saving bulbs.

I'd try a couple first and see if you like them. Plus if you put the code ENERGY15 in the checkout you might get a 15% discount. If it's still current.

I've used led gu10s for a few years now. I've bought from eBay, typically 50-60led units in warm white for about 7quid each.

So while I realise I'm not buying brand names and not very expensive I thought I'd share my downsides:

1). Actually quite dim. Though the room is lit what appears to be brightly if in even partial shadow things are hard to see.... So not good as work lamps. It might sound odd, and would be easier to demonstrate but trust me. Perhaps this is just spotlights in general, but bear in mind room has 8 spots.

2). When one led blows... Lots/all fail. So i have a few bulbs with only 10% of the LEDs still working. And we're not talking monster hours here.... I'd say they are quite unreliable.

That said keep in mind honesty card above. Proper expensive branded may be much better.

Decent LED lamps use a few decent power LEDs, not a bunch of cheap 5mm LEDs. These ones tend to wire a load of emitters in series which is a poor idea.

I've just bought 7 for my kitchen (bought white initially, but changed them for warm white) and three for a bathroom. Only problem in the bathroom is that three doesn't give enough load for the transformer! (I think there is another thread about LED lights in here)

I can't comment on the internal wiring and whether it's a good idea or not, but I have bought both the few Crees and the ones shown in the link. Like these.

As they say in the blurb, these are excellent as spots, but don't have the wide beam angle of the SMD type and are pretty useless for lighting a room. Also, none of these bulbs require a transformer.

These are the ones I use: http://www.ultraleds.co.uk/u10d24cw-...te-5w-55w.html

Mine aren't dimmable, but they look the same.

Not having the glass cover does seem to improve things, and it's not really necessary for LED bulbs.
