If you want a decent colour temperature it's got to run at 2700K to 3000K which means an inherently limited life.
An excellent idea but possibly a bit late in the day?
Apart from the longevity issue raised by Jeffrey, here's a longevity issue of a different sort ...
I wonder how long the traditional ES and bayonet cap holders will last with the decreasing use of incandescent bulbs?
Will new buildings use different fittings from day one, better suited for smaller, lighter LEDs? (Sorry about the pun!)
Rewired buildings would see the same fittings used, in the same way that, in previous times, 5A & 15A sockets were routinely replaced by 13A ones. As the market for ES and Bayonet types diminishes, the price differential caused will accelerate the change.
This new technology, if successful, is likely to take some time to develop. Is it possible that there won't be enough suitable fittings left by the time they become widely available?
CFLs are getting much better - the slow start up of early types seems to have been eliminated, judging by the performance of more modern replacements in our house and, no doubt, LED technology will continue to improve. After all, it isn't that long since LEDs were only available in red. Green followed quickly afterwards but blue was a longer time coming - followed, of course by white.
