After being burned by CFL claims that fell far, far short of package claims on bulb life, I'm skeptical of dropping relatively big bucks on LED bulbs. I'm at least waiting for Consumer Reports to tell me which LED's really did survive their torture tests.
As I mentioned, the electrolytic capacitor is the prime failure point in the LED light bulb. The power supply with these capacitors is right next to the LED and can reach high temperatures which lowers the life of the cap (and the power supply).
Cheap caps (and face it, the bulbs coming from China probably are not using NASA grade caps) might have a life of 2,000 to 10,000 hours. This means it doesn't mean squat that the LED can last 50,000 hours. ...
I assume one of these may meet your needs Let me google that for youI am still looking for a 100W equivalent LED bulb.
It would be nice if they could standardize and make the LED section a plug in to the power supply. Probably not feasible at these costs and the construction of these might be too integrated for that, but if someone wants to push for environmental reasons, it could make sense.

I've been thinking for some time, that our 110V house wiring is obsolete. We should have 12V DC supply everywhere alongside the 110V. In our living room, bedroom & office/dens - there really is no need for 110V any more.
There are still things that draw a considerable amount of power (TVs, appliances in the kitchen, portable heaters, electric blankets, etc). To run these off 12VDC would require much thicker copper wires. For example (according to this site) a 12 gauge wire (the typical size of conductor we have in our home wiring) can carry 23 amps (max) at 110VAC, for a total of 2530 watts. The same wire at 12 VDC can carry 60 amps, for a total of just 720 watts. Stated another way, the wires in our homes wouldn't be big enough to run a hair dryer (typically 1000 watts) if we were using 12VDC.I've been thinking for some time, that our 110V house wiring is obsolete.

The best so far? Philips LED 046677424435 - A Shape
This is true. I actually heard about a British guy that had every outlet in his house wired at 220 volts...........
In a related note, wires become less efficient (waste more electrical power, which becomes heat) at lower voltages.........

Crazy! I heard about that guy--the receptacles he had to use were giant! A 6-outlet power strip is about 70 CM long (which I think is about 5 feet). What really herz is that he could only get the power to run at 50 cycles per second instead of the proper 60 cycles.This is true. I actually heard about a British guy that had every outlet in his house wired at 220 volts.
Sarcasm I assume.This is true. I actually heard about a British guy that had every outlet in his house wired at 220 volts.

OMG!!!
Do you feel a tug on your leg?Isn't that the British standard? Or is this a Brit living elsewhere?

If we went to 400 Hz, I don't know if this old wiring could keep up that pace.........However, going from 60Hz to 400Hz like aircraft power makes sense, don't you think? ........
The detailed knowledge available on this forum on just about any topic always amazes me.
