Yes, it’s because they drive the heck out of the LEDs to get their maximum rated light output. This produces excessive heat, shortening the lifespan of everything inside the case, including the very cheap electronics they use to rectify mains AC.
In Dubai they actually have efficient and long-lasting LED lights [1]. These exist in order to satisfy strict government regulation there. They’re not sold anywhere else because they’re more expensive to make (more LEDs per bulb running at lower output).

- Helmut10001 2y agoI would gladly pay more for longer lasting but environmentally sustainable ones! Another case where government intervention seems necessary and there is no real "corrective" force with only capital oriented companies.
- bitslayer 2y agoCapital oriented companies can lead to the correct outcome if the consumer has enough information to distinguish the superior product. One solution to this problem that capitalism has found is UL Listing (Underwriters Laboratories.) Of course you could say they are just outsourcing what should be done by the government. It comes down to who do you trust to not fall into corruption.
- weberer 2y agoSo just import them from Dubai? Or you could start a company and start selling long lasting lightbulbs yourself. Its not like you need a team of super scientists to design a LED board with a bigger heat sink. Its weird how so many peoples' first thought is always to have the government micro manage everything through legislation.
- mobilio 2y agoIt's not only heat from LEDs but also from power unit that LEDs uses. They transform electricity from 220V sine wave (AC) here to 5V DC. In 90% of cases where LED need replacement problem happens in this transformer unit. In rest 10% it's on LED fault - but it's also problem because they are series connected and when one is gone whole circuit stop. If they are parallel connected such issue won't happen.
- xxs 2y agoThe LEDs are not driven at 5V - that would be one of the worst voltages to be driven. The LED bulbs are driven approx at 3.2V x number of LEDs. (some LED chips may have 3-4LEDs in series as well)
- Mistletoe 2y agoI find it completely ridiculous you can’t buy these anywhere else or it is very difficult. Lends credence to the theory that we are in a new led bulb light conspiracy. I don’t think I’m the only one that would like to buy an over engineered LED bulb that will actually last as long as it should.
- TristanBall 2y agoYou can buy them in Australia, or at least the bulbs sold here by philips as their "UltraEfficient" range look the same and match the specs of their Dubai bulbs marketing page. They don't appear to be available in the US though, that's true. I think I'll get a couple to try for those places where I think "60w incandescent equivalent" is sufficient, although cynical experience tells me to expect 40w at most - but for low single digit wattage power draw I'll accept that in some places. Mostly I like to see though, so I'll keep buying their 150w equivalent bulbs.
