LED GU10 dimmable bulbs

[ivahunch]

I am quite pleased with Lumilife LED GU10 bulbs. But does anyone know the best make of LED GU10 dimmable bulbs?

Any special reason why you wouldn't want Lumilife's dimmables? I'm pleased with my G10 downlighters from LL. (They even work with a non-LED dimmer switch.)

Some LED brands erode the certainties that you'd normally expect from issues such as lumens or kelvins. My daughter bought a batch of low-priced Chinese jobbies that arrived in a box whose label said something quite different from what she'd ordered. It turned out that the bulbs were okay, but that somebody at the factory hadn't thought it was a problem to ship them to the other side of the world in the wrong boxes. Hmmmm....

LedHut has sold out and I don't know where else to get them!

Slightly o/t but I bought six Philips GU10 non-dimmable LEDs to replace halogens
Three had failed within a year, and now all six have gone after two years, against a claimed life of '15 years'
Paying a bit more for a respected brand doesn't always get you better performance

Never seen anything like that, with bulbs of any kind! Is there perhaps something "interesting" in their situation or power supply?

Yes, I've had short-lived LED bulbs from a couple of DIY sheds, and I've stopped thinking of Philips as a premium supplier because their quality seems to have gone down the pan as well.

15 year guarantees are a bit of a joke, if only because you'd have to produce the receipt and possibly the packaging to make a claim on them - and how many people would even bother on a three pound item like a light bulb? Not me, for starters. That, of course, reduces the manufacturers' guarantees to a cost-free marketing ploy. Which, I have no doubt, is all in their calculations?

The replacement Wilko and Sainsbury's ones are doing OK so I think the power supply is clean (I'm a a relatively new place- c2015 build- and all the electrics are fine)
I know 15 years is a 'typical' lifetime but 6/6 fail within 2 years is pretty poor even if they are getting more than average use. They are NOT on permanently!
Given they were c £15 I tried to complain on the Philips website but it wouldn't accept the item number...

I bought 3 of these in June

Last week putting a jumper on I caught my hand on the 3 light ceiling fitting and one of them just went out (we have low ceilings in some rooms). Not even a hard knock, just enough to move one of the swivel holders slightly. Swapped them around but still no joy - failed bulb.

Rarely stocked too, fortunately I'm back in Devon this weekend so can collect another.

I do wonder if you purchased genuine Philips GU10s, there are fakes around. Some can look quite convincing. I have used Philips LEDs MR 16 in specailist fittings and they have been excellent, in fact the transformers go before the lamps.

A statement of 15 years life is not very useful. Lamp life is normally specified in hours i.e. 20,000 hours and switching cycles say 50,000. The fitting is also important, LEDs do get hot and a very enclosed fitting can often lead to early failure.

I would avoid the big DIY sheds who are mostly interested in selling lamps with the largest profit margins, rather than any concern about the quality. Go to specialist trade suppliers whose main customers will be electricians. Most electricians don't want install rubbish which will rapidly fail, causing a call back and unhappy clients.

I have used simplyLED at the address below and they were fine. I bought LEDs from tem about three years ago and have had no problems.

They 'look' genuine - bought from Amazon , and in authentic (looking) packaging. They appear well made, glass encapsulated rather than plastic.
I noticed they started to get noisy before they failed so guessing the SMPS is failing rather than the LED elements
Yes 15 years is a bit vague, they are also quoted as 15,000hrs and 50,000 switching cycles
I probably average 2,000 hrs per year maximum, minimal switching. They run cool - I checked

It wasn't Amazon Marketplace? This has a bit of a reputation for fakes and dodgy products. It is also rather suspicous that the Philips website didn't recognise the number.

Normally the power fails first. In the GU10 this packed into a very small space. I can assure you this does get hot and heat is the enemy of all electronic components causing early failure. This why some electricians prefer to fit 12V LEDs with a seperate power supply, which will run cooler and can be easily replaced when it fails.

Take 'em back. Demand your money back. They shouldn't be allowed to get away with inaccurate advertising. If you/we don't do this they won't change. C.
