Re: A solution
14 thumbs up over the weekend.
On a more expensive note in the UK and a reminder of how woo factors can affect us all: many local councils have taken to switching off street lights for part of the night (1am-4am) - most being flourescents on minor streets.
A quick calculation shows that the power savings is about 40p/year (at most), whilst the lamps are about £8 apiece and replacement cost is about £50 each (labour charge).
The average life of a flourescent tube is 8000 hours (when run 8 hours per day) or 1500 cycles. If you run them 4 hours per cycle then this shortens down to about 4000 hours - the cycle limit is due to the filaments in the ends of the things and electronic starters don't make much difference.
So in order to save a few hundred thousand pounds in electricity charges, councils are spending millions with lighting contractors instead (It's not an issue if they're LEDs of course, but led lamps can be dimmed down to 10% brightness/power consumption and instantly perk up if there's movement detected underneath).
Nice scam if you can sign up for it.
