Most led lamps are overdriven, which is why they fail. Bigclivedotcom on YouTube has loads of videos, including some which show the driver circuits and how to modify them - in particular one which refers to a Dubai led lamp. It seems the lamp manufacturers just can’t help themselves from designing lamps that are intended to fail.

@fizzy i have found my fluorescents perform much better when they aren’t coated in half an inch of grinding dust!
I changed a couple recently and and the difference in light output between an old grubby fluor and a new one is quite astonishing. A big downside to them is how easy they are to break. I’ve smashed one or two this last 12 month because of very low ceiling heights and if I didn’t have a good supply of these I’d have certainly swapped to led. The stories of them lasting a short period of time always put me off, and I don’t particularly like how leds cast shadows, areas seem to only be lit or unlit, nothing in between where as with fluorescent you seem to get a bit of bleed around objects.

I did think of that, after I'd put them upIf you had a decent controller on them you would have a great disco! My brother has them all over his bedroom and can set them up to have multi coloured displays with lights chasing each other all over the room
That's the problem people aren't comparing like for like. The difference in just cleaning the diffuser with warm soapy water is incredible.
I have a mix of new LEDs v fluorescent and the difference per watt is negligible. LEDs are so much easier to install though.

Bigger differences between a proper led fitting and just a tube replacement though, proper fittings give something over 115-130 lumens/watt. Sticking an led tube in a fitting designed for fluorescent tubes is always going to be a compromise...People replace knackered ancient light fittings with LEDs and think wow! A lot of it is down to colour temperature. Whiter lights appear brighter even though they aren't. When you look at the actual lumens output between LED per watt and traditional fluorescent there isn't much difference. Throw in the poor lifespan and I think the savings are debatable. The main advantage of LEDs are they are much easier to install.

Even if that were the case that might be much less mass and reduced toxicity - than fluorescents going the same way. Buy cheap, buy twice is an age-old adage which a lot of people either don’t understand or choose to ignore.

That is why I went with Philips, big name, bit more expensive and should be good but in reality they are totally crap and have been from the start. The Lapp battens I have in the plasma shed have been in there for probably 5 or 6 years and still going strong, have never flickered unlike the bloody Philips rubbish.
My lap 5w gu10 replacements haven't been much good. Don't last long at all. The tubes are fine for now but don't get much use since I upgraded all the warehouse lights.

I’d been watching this thread as was thinking of upgrading the garage with led.
Just been to the tip and helped a guy out with a filing cabinet into the wood skip. he just so happened to be skipping a discovery boot full of new 600x1200 60 watt led panels and ip68 led strip fittings, what are the chances

We have LED GU10 units in every room downstairs in the house. I am constantly replacing them - probably go through a box of 10 in 6 months. I have found the more expensive brands seem to last a bit longer but still nowhere near as long as I'd hope. The old 60w filament bulbs used to last several years and were a fraction of the price. I'm struggling to see using LEDs actually saving me money.I have found the Led replacements for the G9s in our kitchen are useless. Too yellow and they keep blowing.

Not too difficult. Check how long the ‘burn‘ times are and compare the energy costs to run at a few Watts for the LED and 60W for the filaments. I note screwfix are offering a 3 year warranty (with limitations).

Going to need shades. Theres 6 60 watt panels with drivers (one looks like a customer return) . 4 36 watt panels, and 9 110v IP65 non corrosive flourescents, which I think I will stick on marketplace. Just need some timber batten frames up

Hope you are lucky and get the same connector. Fitted for about the same time as yourself, bought some more from the same supplier and the connectors are not compatible. I dont see a drop in performance, though mine havent been on much this last 2yrs.

Got them in the week and just fitted a couple. They are a direct swap so no problem there.
Here is a new one plugged into an old one. This one was one of the better ones, some were dark 6" from the end and one had gone off completely.

The 6 Ft Phillip's ones saved me more money 2 stopped working after 2 years the other one went to 50% working intermittently all the rest of the house and outside lights are at least 4 years old those 3 were the last to be changed trying 3 x Osram now.
All the main workshop lights Hi bay are over 6/7 years now no problems about 20 batten ones all ok a couple of flood's have failed but one was replaced UG after over 3 years

Its all a tad confusing, I have resigned myself to having to change these tubes on a regular basis and now buy local so I can take them back. Just looking at lum output vs watts, typically about 90 lums per watt with tubes vs 130+ lums per watt with the hibay led`s. In time I think I may swap over to the hibay type.
