Re: Nah.. They won't be getting a grilling..
An LED lamp is a combination of these components:-
1) The LED chip aka the diode.
2) The heat sink
3) The power supply
I'm looking forward to finding out how long my filament LED lamps last. They dispense with the heat sink relying on convection to cool the suspended strings of LEDs. Helium filled ones are claimed to have better cooling than old style heatsinks, it's believable even in plain air they do well enough. The 7W bulb above me is just warm to the touch right now after hours on.
They also need much simpler power circuits to feed those serially wired LED strings, in theory you could even run them off mains voltage with just a bridge rectifier. A simpler, cooler PSU is guaranteed to improve lifespan.
I bought them to replace CF bulbs because they look good, after rejecting fugly old LEDs for years, if the reliability claims pan out that's a massive bonus and potentially will become a much cheaper LED bulb because of the simplicity.
