How many spotlights to replace fluorescent strip light?
I am currently refitting a kitchen which measures 3.4 x 2.5 metres (11' x 8'6'), which is currently lit by a 1.5 m (5') long fluorescent strip light. The wife wants to dispense with the strip light and install a more stylish looking set of 4 spot lights, but does not want a darker kitchen. How many conventional incandescent light bulbs or halogen or tungsten spot lights would I need to match the fluorescent light output?

It depends upon the brightness of teh spotlights you want to install. What wattage is each one?MarkJP wrote:I am currently refitting a kitchen which measures 3.4 x 2.5 metres (11' x 8'6'), which is currently lit by a 1.5 m (5') long fluorescent strip light.

Light output is measured in Lumens, if I remember rightly.
A flourescent tends to spread light in all directions whilst spot lights direct the light in one direction. There are lots of factors to consider such as will all 4 spot lights be in a line or will they be a distance apart. Or where you thinking of a rail that has the spot lights on like the picture attached?
For a rough guess I would say 4, but that is just a guess- or get one like the light in the attached picture.

The luminous efficiency of filiament lamps is around 15 lumens per watt, fluorescent 80 Lm/W.
So you need 300 W of lamps in total. So if you have four, each should be 75W. Or six at 50W.
This is only a broad comparison; as pointed out above there are other factors than just the lumen output to consider.
