Americans can't even measure gallons correctly. So there's no hope they would understand fundamental physics...
Mind you, some Anglo numbskulls can't spell Lava Bread. What is the world coming to?
Surely you mean "Laver Bread"? Speaking as a man currently sitting in a small cupboard which, if it had a window, would have quite a nice view of Swansea Bay...
@Andre. Could I offer the possibility of an "applied engineering vent" for your next thread. I offer the low energy light bulb. You know...the ones that are 'supposed' to last 8,000 or 12,000 hours (note the commas not full stops).
Think you'll find that the comma-full stop reversal is a continental European thing, specifically the French
How long do yours last? and...
As for the applied engineering, as a user of many, many "low energy" lamps of various varieties (e.g. LED as well as CFL), in my experience it isn't the lamp that fails; it's the power supply, particularly those LED ones - the LED itself works fine for many many thousands of hours; the switch-mode that drives it usually fails first. I write dates on most of my lamps at home and 10,000 hours wouldn't be unusual for many, but it varies according to brand, usage pattern etc. etc.
Have you ever noticed in the middle of the night one of these lamps, having been turned of as bed calls, starts pulsing with light at about 1.666 x10^-2 Hz

This sort of symptom is common where you have a leakage current. For example, at a previous house I had a light switch that "lit up" when the light was off, so that you could find the switch in the dark. It did this by putting a Neon indicator across the switch. With an incandescent lamp, just enough current would flow to light the Neon but wouldn't do anything to the incandescent. Older-type CFLs would often have capacitors across their incoming, which would slowly charge through the Neon until there was just enough power to strike the lamp very briefly. Newer CFLs have a bypass resistor to allow the Neon to light without charging up the PSU.
Some types of light switch timers or ambient light sensors power themselves in the same way and could cause the same symptoms. If your light has none of these things fitted, get the circuit checked by an electrician for insulation resistance and leakage - this could be a good warning of a latent problem.
