LED lighting is actually delivering what the CFLs
falsely claimed, provided one
doesn't need more than about 400lm per bulb due to heat issues. For the
customary single bulb per room in typical UK lighting, it means we're stuck
with CFLs until the technology improves or one replaces the light fitting with
one that takes multiple bulbs. We'll probably see a whole load of crappy LED
bulbs when that finally becomes mainstream though.
I'll buy CFLs when I can safely put a 100-watt equivalent LED in a
base-up recessed, insulated "can" type fixture (of which I have many)
and expect it to perform for the estimated lifetime.
When I contacted the manufacturer (GE) for some CFLs in the same
configuration pooping out after about 6 months of service, I received
the response that CFLs were not designed for that type of service. When
I inquired for what device does operate in that configuration, I
received the response that a halogen bulb would do nicely.
Last year, during a very wet snowstorm, our power was interrupted by a
tree falling on the HV distribution lines to the neighborhood, my
neighbor who'd just refitted his home with LEDs lost every single
installed lamp. We (on the same circuit) lost none.
I think the CFL would not be viable were it not for cheap overseas labor
needed to assemble the ballast unit components.
