I was about to buy some strip lights for work,
2x 4 foot flourescent tubes, (36x2 watts).
I'll be buying 5. Looking at the projected yearly savings it will take
about 4 years to break even given the extra costs of the LED units.
So unless they give off better light, or last for ages, i'm struggling
to see the point.
My DW is absolutely brilliant at spotting spelling errors. If we go to a
restaurant and there are no spelling errors in the menu, she is terribly
disappointed. She'd have a field day if she ever found usenet. :)
It's an easy mistake to make --- I know how to spell the word (out
loud, for example) but still sometimes type it wrong, I guess because
"ou" is more common in English & therefore in my finger memory than
Where I have replaced CFL's with LED, a big advantage I have noticed is
that LED's are instant on and at 100% brightness. There is also no
start up consumption or wear and tear penalty for LED's.
I have one 5' fitting, which is on an occupation switch lighting the
utility room. The room provides access to a pantry and a big freezer,
so is constantly being visited, so the tube is fired multiple times per
day - an ideal situation for replacing it with LED, when the prices
fall. I might even get around to making something up using more
conventional LED lamps.
apart from early days of the tech*, its been rare to see LEDS fail,
though IIRC the dopant migrates and they lose brightness over time
I would say that they are now coming up to the sort of period - 20 years
plus - where there is no excuse for failure at all.

In one of the sheds is a 5' florry, starts OK although it's an old one.
There's 1 spare tube, but I'm very tempted to get 5 batten holders and
5-for-8-quid 800lm LEDs from SF. 4000lm and instant-on, spread along 5 - 6'
would be a pretty good light.
