Thank you. I asked because of a question on radio this afternoon - someone
asked what to do with defunct low energy 'bulbs' and a panellist said that
they could be an environmental hazard and implied that the future was in
LEDs.

Ha! Nothing is a hazard if recycled correctly. You wait til the enviro-
winers find out that LEDs contain arsenic!

Well, yes, but they'd only need to be replaced every few decades. The
lamps, that is.


We had *loads* of these at a previous place of employment. Large ones,
small ones, round ones, square ones, red ones, blue ones, white ones...
and they are *not* indestructible. The LEDs are arranged in a matrix,
and a failure of just one will take out a whole row. Out of some 40
(ish?) in the ramp outside the main entrance, at the time I left there
were a good 8 or 9 with a fault like this. In others the whole thing was
off, but in this case it was usually the transformer which is easily
replaced.

As for domestic suppliers, there are a few in a catalogue I have from a
company called "QVS" (http://www.qvsdirect.co.uk/ ): 240V versions with
15 LEDs in white, blue, green, red, orange from £12 upwards. Also other
versions of similar products including some outdoor (IP68) "floorlights"
with 4 or 9 LEDs in blue or white for £22.50 or £29.95 and which require
transformers.

As for power consumption, the 240V things are 1.8W, but quite how much
illumination that gives is anyone's guess.

Hwyl!
