Proper Residential Lighting Levels

Does anyone know what the proper or recommended lighting levels (foot-candles) are for residential homes? Is there a web site you can refer me to?

I'm trying to determine the wattage and quantity of can-fixtures for my den (in the basement). The space is 18'x15' with 7'-4" clear to the ceiling tiles. I already bought can-fixtures that can handle upto 75 watt bulbs. I figured on installing 6 fixtures.

The general rule of thumb is 35 foot candles in living spaces.

This works out to between 2 and 3 watts of inky recessed lighting per square foot.

Your six 75-watt fixtures = 450 watts in your 270 s.f. space. Add a couple of task lights and/or reading lamps and you're up to "suggested retail specs."

You also might find that 35 foot candles is a LOT of light. Consider putting the cans on a dimmer for those times when you're not vacuuming.

Rick's advice is perfect. Six cans sounds right for your room (depending somewhat on ceiling height, wall color, planned activities, etc). And I agree with Rick that you will probably want the dimmer.

See this web site for more information.
