Now normally LEDs are either pants in terms of light output or horrifically expensive (£20+ each)
However I was on Ebay and I bought 2 different kinds of LED bulbs 2x 60 LED Surface Mounted Diode (SMD bulbs) and 1 x 80 LEDS, all 3 W. All CE marked and ROHS.
The photo is the light I get (cool white) No flash used in this shot, nor any jiggery pokery.

Not too bad I think...and a lot cheaper to run than 3 x GU10 50W Halogens.
If anyone wants to know where I got them from, just ask and I'll post the name of the company I bought them from.
Guy was telling me the SMD bulbs in warm white are his best sellers as they are so close to normal halogens, I prefer the cool white though, I find it a cleaner light.

Oh forgot to mention, the SMD bulbs cost me £8 something each, the 80LED bulb cost me about £6, both specced at 50,000 hours, though I'll believe it when i see it :wink:
What I have notice is a much more even spread of light compared to the previous halogens, room no longer has areas in total darkness though still has the areas highlighted that I wanted to highlight.

BA: The ones I got were GU10 bulbs (same as 240v halogen spot light fittings), the guy I bought from charges £1.90 for the first bulb +10p per further bulb on Ebay or £1.50 flat rate on his own site (use discount code: ebay to get a discount on his site)
However he doesn't list the SMD bulbs on his site, when asked why, said he can't keep them in stock as he sells so many on ebay.
Link: www.ledbulbsuk.com or led-lamps on Ebay. I bought all mine on Ebay just for convenience and I wanted the SMD bulbs as I prefer the minor increase in brightness over the 80.
I only tried the bulbs as they were a third of the price of similar elsewhere, and was pleasantly surprised, to be honest I wasn't expecting much from them, thought they would be really dim or blow up in a matter of days.

Most LED lights fail due to heat disippation problems (the lack of...). If you fit the lamp into an enclosed holder or one without a decent free flow of air then it will fail a lot sooner than the quoted hour rating.

Quite a few of these LED lamps are originating from China - not all are 'bad' but a lot are sold as full-spec when in fact they are manufacturer rejects so caveat emptor.

KE:
Good point, mine are alright as they are in a 3 spotlight fixture so the bulbs are mainly hanging in free air with the base held within a metal holder arm.
Seller mentioned they are made in the same factory as well known bulbs, told me that they were not rejects, just made under a different name without the markup.
I'll see how they go, I run mine for 6 to 8 hours a day or more in my living room.
So if they blow I'll soon find out, checked his feedback and no mentions of them blowing prematurely thus far and he has been selling them for over a year so thats of some comfort to me.
Its an experiment that thus far seems to be working out ok and is currently resulting in the electricity meter spinning slower :thumbleft:

I'm all for energy saving and recently did a full house 'test' to show Mrs k_e where all the juice was flowing (oo errr missus....) and it was quite an eye opener. We found that we could actually save nearly £300 per year by switching all our printers off each night :shock: :lol: ( mind you we have FIVE laser printers running most of the time :roll: )

Lighting is one area where I'm still suspicious of any effective savings - some say the actual heat produced by filament lighting contributes to the heating of the home anyway and that using low energy bulbs means that the heating itself has to make up the shortfall :dunno:

I'm now fitting timer switches (touch-pad, variable delay 0-2hours) in our workshops/offices so we have to make a conscious effort to ensure heating (etc) is powered on - else it pops off after the set delay. Stops us leaving it on permanently (coz we're lazy that way :lol: )

I was looking at some low energy dimmable replacement halogen gu10's. Found a pack of 10 for £8.50 including delivery. They are not low energy but a cheap temporary replacement until i can find some. Also dimmed must be better than the full consumption.

Just seen lidls have some led ones for £5.99 each

Each bulb has 15 long-life LEDs
Bulb life approx. (hrs): 25,000
Beam angle: 90°
Colour temp. (k): 3000
Choose from MR16 GU5.3, E27, E14 or GU10

But £22 each, i have 4 bulbs in mine and some have 5. Would have to come down in price for me to consider something like that.

there are plenty on the market all varying in cost and quality. For an entry level set which i've installed on a number of times check without issue

I pay £50 +vat so anywhere in between £60-70 inc is fair
