How many spotlights to replace fluorescent strip light?

Post by MarkJP »

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?

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.

You can now actually get fluorescent recess lights now. They are only 7watt and obviously not as bright as the halogen bullbs.

No info on the net for them. But I did get have a leaflet about them from the wholesalers.......somewhere
