In my kitchen I have two rails each has four 40 watt halogen
lamps in....I wish to replace these fittings with Fluorescent
tubes........What size tubes will I need to get the same light
output and will they be cheaper to run ??
They'll be a *whole lot* cheaper to run for two reasons:-
They use less power to get the same amount of light.
The light is more useful so you need less of it (they are not so
directional, don't cast shadows, etc.)
I'd go for two 4ft tubes or two 5ft tubes, whichever looks more
sensible. They'll take about a quarter as much electricity.
40 watts is an odd size for a halogen lamp. Usually they are 20, 35 or 50W.
I would expect one 5ft tube to make a kitchen brighter overall that any
combination of 8 of the above.
Do as Chris suggested and fit a couple of 4 or 5 foot tubes depending upon
what looks best (maybe even one 6ft tube).
