New LED lights reliability

<< < (14/24) > >>

well I just realized that A70 is a metric designation, which is really confusing and stupid. But yes it still won't fit most household fixtures.

I question the usefulness of LEDs for retrofit use, after you consider all the factors performance, price, reliability etc. Especially where electricity is cheap.

Psi:
If you want long life LED lamps you can always buy a high power LED lamp then take it apart.
Modify it to reduce the power down by 50%. That will boost it's lifespan A LOT.
Since heat is the number 1 killer of led lamps.

Need 20W, buy 40W and modify.


Obviously it takes some effort and maybe you can't be bothered, but it will definitely last MUCH longer.

That's not here, over say 10000 hours a 100 Watt bulb costs me 200 Euro in electricity.

There already are reliable and long lasting LED bulbs, this problem has been solved for years. I have some from 2011 that are still working, even the ones that have run 12 hours a night on a timer all this time. How long do you need them to last?

The biggest filament type I have are 800lm (60W equiv) I'm not a big fan of that type though. They tend to run cool since they have a large number of emitters driven at low current so they work well in enclosed fixtures but they also lack space for a proper high frequency driver so I find they have perceptible flicker.

Marco:
Why would a proper high frequency driver be large?
