I'm trying to order the 35W ones but keep getting the message:

The following errors have occurred...
There was an error while moving to the order commit screen

ever since i went from these halogens to led bulbs, I aint never getting them again. 35W/50W down to using 5W per bulbs is a no brainer in the long sense. PLus the fact the halogens kept going out and having to replace them regularly...

Nevertheless not a bad price for these for a pack of ten, can't grumble too much. Have some heat for the spot :)

Edit: the ones am talking about are GU10s, not sure if these MR16s would be any different tbh...

Ordered 2 packs of each for £3.

Just moved into a new house with these down lights in the kitchen and dining room. Want to change to LED but need to work out what's going on with the wiring and transformers first and these will keep us going in the meantime. Thanks OP.

I still can't seem to order any. :(

I ordered some 2 days ago and they arrived yesterday. I just needed a cheap replacement bulb since I hopefully won't be in my current property much longer, the investment in LED bulbs wasn't worth it if I'm moving.

It's fine saying LED are better but you fail to say that a single bulb is often £5 each!

Awesome

Stupidity + false saving.
10 led bulbs for £25 on amazon.
You'll more than save that 25 pounds in the 1st year.

Of all the lights to benefit from led these spotlights seem the best, you have loads usual2so huge wattage use and I was personally changing about 1 a week it seems. Led now and must say I am loving it, no dead bulbs so far and all the lights for the wattage of a single halogen.

Great price, but real bargain hunters look for the lifetime cost. Plus if selling the old led spots make a decent difference to your epc I believe.

If you try to change 12v MR16 bulbs for LED you will often find it wont work as the transformer can't handle the low wattage and the bulbs all flash, you then have the choice of leaving 1 or 2 old bulbs in or changing the transformer. It really depends on the transformer but most can't cope with the very low wattage.

These are not half as easy to change for LEDs as the 240v GU10's.

I have this problem in my bathroom.. had to leave 1 Halogen in. Is there a solution to this?

Bought the 35w since other one was sold out. Thanks op.
#14
OP and Gringo many thanks, just ordered the 35w, 50p for a pack of 10, absolute bargain!

The only cure is to change the transformer for an LED driver or leave one old bulb in place (as you have done).

There is so little wattage with LEDs the transformer can't cope, if you look at the data badge on the transformer it will have a minimum wattage as well as maximum.

Mostly these low voltage MR16s are only fitted in bathrooms so you don't get the big hit you get from changing GU10 which mix people mix these MR16 / MR11 for.

I have 5x MR11 20w in each bathroom, I could change them to 5x 1w LEDs but would also have to change the transformer to an LED driver and the saving in a bathroom does not really make it worthwhile, it's only on for a hour or so a day.

I've got 9 of these in my kitchen alone.

9 x 50 = 450W = Killer electric bill.

I've changed over to LEDs which are a lot more to buy but a lot less to run. You'll be finding these old Halogen Bulbs getting cheaper and cheaper till no one wants them and they stop manufacturing them.
#17
Great price! Heat added :)

Just converted all but 5 bulbs in my house to LED, not cheap but shouldn't be too long before I see the reward

Whole house is less than 100w now :D

we have 12 led bulbs in our house, 2 have blown within 3 months!
ordered these http://www.amazon.co.uk/gp/product/B00D5LK9S4?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00 at under £14 (now £17)
just hope they last

Avg yearly cost of 5w LED =£1.37
vs Avg GU10 50w =£13.69

even if GU10 50w was free I would be better off paying £5 per LED bulb

simple math! :-)

For a start off in England it's MATHS not MATH.

LED lamps are ridiculously expensive and do not last anywhere near the claimed lifespan, thus all calculations versus GU10 mains halogen are utterly redundant! I have always bought and will continue to buy NON ENERGY SAVING NON LED lamps, even more so now as they are reducing in price daily! Cannot believe the amount of people out there suckered into buying all the supposed energy saving crap on the market.

Thank you. I shudder at the creeping use of 'math'...keep up the good work!

These were £4.50 each in tesco! I've just ordered the 35w bulbs for store collection - I had no problems and they've text me to say they will be ready on Saturday
#23
If anybody here has changed from these MR16 (GU5.3) to LED and NOT had transformer problems can you tell me the LED make/model please? Cheers

So if change all the bulbs in my bathroom except 1 from halogen to LED, do I still need to change the transformer?

If you have MR16 (same as GU5.3 and is 12V) then each fitting will probably have its own transformer. You have the following choices if going to LED:-
1. buy a LED and see if it works (if flashes or turns off then keep reading...)
2. depending on how many lights you have (e.g. 5) then buy 5 LED bulbs (e.g. 5W each so total would be 25W) and run ALL off one transformer (wire the 5 bulb s in parallel to the transformer)
3. replace all transformers with LED "drivers" (basically low wattage transformers)
4. replace all fittings with GU10 (run off 240V and don't need transformers)

Yes, its a mess.

I've been using GU10 LED lights for 3 years. In that time I've had one go on me out of 29.
So in 3 years I've certainly had a return in my investment, despite what you think. In fact every light in my house is now LED, except the garage. My potential lighting power usage heads dropped from over 1300w to under 300w. How is that not energy saving? Yes the bulbs require resources and have environmental implications in their construction. My environmental concerns begin at home, so the cost of the electricity comes first.

One thing many people fail to take into account is as energy consumption for home lighting decreases so does the warming effect of old incandescent bulbs, some people have responded by having to notch their thermostat up a little, there's a small cost to that although almost certainly not the equivalent of the 1kWh you're saving now.

Not picking holes in your comment, just mentioning something that people sometimes forget to factor in. ;)

Fair comment, I've heard that argument before. However as heat rises, most light bulb heat is wasted anyway. Also I'm also including exterior lighting, cupboards and loft lighting in my total Incandescent abstinence. Places where heat is irrelevant anyway. My it should also not be forgotten that most GCH systems cost less to run that additional passive heat sources like bulbs.

Again not picking holes, just giving a constructive counter comment ;):)

The one thing I noticed is you do have to factor in total conversion costs. I was looking for a cooker hood to go in our new kitchen with LED in it. The cost leapt over £400 to get on so I didnt. Turned up the one we chose took standard GU10 bulbs anyway so was changed for £8 :)
