LED light bulbs

Hi Victor, thanks for the reply. Mine are spaced out and from having a play, I think each individual bulb has it's own power supply. Any idea how big a job it is for a sparky? Only 6 downlighters in total. Expensive job or not?

If each bulb has its own power supply then each one must also directly be on the lighting circuit, so possibly no additional wiring to do.
In that case, it could probably be done from below as well, so no need to get into the ceiling space if it isn't readily accesssible.
Might still be covered by regulations as it is a bathroom and you'll actually be replacing the light fittings. Needs someone who understands the regs to answer that one.

Don't know if this is suitable for anyone, but the company I bought my bulbs from have just started selling on Amazon and have sent me a discount code to get 15% off their brightest LED bulbs, so helped myself to another pack of 5!
If anyone wants the promo code, just drop me a message

Bought some Philips LED GU10s recently and pretty impressed (though they need a few hours wearing in). Not a replacement for a 50W but matches a 30-35W GU10.

It seems the prices are coming down slightly now, Wickes selling them for £9.99:

(don't forget 3% quidco).

Wickes have demonstrated one of the biggest problems with selling LED bubs and should no better as a big retailer. They list NO specification that is relevant to the bulb!!
How can you know what sort of bulb it is if they don't tell you the following:
Lumen Output
Halogen Equivalent
Angle of light
No. of LED's

Quite frankly it's pathetic, it's like advertising a car without mentioning the engine size!!

Rant over!

I found these to be perfect, UK seller, decent price especially in larger packs (£4.50 each for 10) with 60 5mm LEDs in a good 'warm white', similar size to standard GU10's and with 120 degree angle suitable for general lighting. They seem close to the output of Halogens, bonus! in a 'new' installation like I am doing I can add lights willy-nilly at only 3 watts a pop!

You think those are perfect? You think LED Spots that make your room green, constantly flicker and make a buzzing noise while they are on are perfect?

Here is a bulb you say is perfect in a standard kitchen:

Here is a 50w Halogen in exactly the same standard kitchen

Would you care to change your mind that these spots are perfect? The difference is so great that some might think you have some sort of affiliation to Lustrumlight? (the company that makes the green, flickering and noisey spot light)

Absolutely correct and they always embellish every single statistic as it's very hard for someone to prove they are wrong.

I think these are pretty awful personally and have very little suitable applications. They are certainly not an equivalent to a 35w Halogen.

Great post! :beer:
I have been on a similar adventure. I got some decent 4 big LED ones that had immense output but were too focused which is the other point to raise here - beam angle. Many LED lamps around have 20 to 40 degree angles which make good spotlights but are so not good for general lighting. You need to look at ones over at least 90 degrees for that.

Another factor beside the number of LEDs on multi-LED types is the size of the LED used. Some use 3mm ones others use 5mm which are a lot more powerful.

Are these the same awful LED spots you recomended to me on another thread? Thanks a bunch, spent £50 on 10 of them off ebay and they are without doubt the worst spots i've tried.

They made my kitchen green, it was like living in a teenage mutant ninja turtles cave, they get incredibly hot - just like halogens, so i'm guessing they are not the best energy saver (so whats the point), they constantly flicker and without the tv on, they buzz when turned on. They do produce a more even light across the room, but this is an awful product overall. Avoid like the plague.

I think i'll be ignoring everything you say on this matter from now on.

Missed this, exactly the same as my experience.
They don't state what wattage they are ?
They also burn really hot, so bearg in mind halogens lose most of their energy through generated heat, i'm guessing these are a pretty pointless LED?

Wow, elstimpo - talk about a picture painting a thousand words! Those photos really show the difference. Thanks for posting them and for the warning. Definitely ones to avoid.
