What brand ?
LG 110 cm diagonal.
In fact it was 4 bars of 52 leds, but you have to have space and be organized, a real mille feuille : Shock:

Only one experience at home with LG: A washing machine, gunned down in 1 year. Fortunately reimbursed thanks to the insistence of Que Choisir, the manufacturer not wanting to hear anything.

Comments like that will always find you on all brands. She was 7 years old, the person bought another. This one cost me 25 roros and has been running for more than 2 years without worries and now I know how they are made. :P

Except that there are brands that are more reliable than others. moreover, you are never safe from hitting the wrong number.

Nothing is less certain today or the manufacture is made of parts coming from all horizons. and where the brands are bought by multinationals ...

Some, like Samsung (certainly also D'aurtres) outsource the low end but manufacture the high end from A to Z.

For the basic components too, there are good suppliers and gougnafiers. Saving money for a capacitor (for example) is common, putting a power supply "too tight" too.

By the way, thank you to the electronics industry for having succeeded in producing what environmentalists concerned with energy savings have dreamed of, these LEDs which have divided by 7 the energy consumed for lighting, compared to lamps. filamentous.

The first LEDs in the visible, red, it was in the 60s, and far too weak for lighting. It took 50 years to get very bright white ones.
It takes technologies to advance technologies, it takes work, it is a synergy of all academic and industrial sectors that advances surely but slowly.

It is not by decreeing that we need less polluting energy, that we will have it. It is not by banning the heat engine of cars that we will have such an effective alternative.

Progress cannot be made by forced march with a yakafaira otherwise we tax or keskonattendpour otherwise we forbid. These recurring requirements in ecologism are the lot of useless ignorant people who have never put their hands in the dough and of pretentious incompetents who believe themselves to be the only ones with concern for ecology. However, it is not them but the traditional industry that made the LEDs. If they produced as much innovation as they produced vituperation, we would not even know what clean energy to use, so much we would be spoiled for choice.
