Example: A room is 12 ft. x 16 ft. Multiply 12 x 16 x 1.5 = 288 watts*. A ceiling fixture designed and rated for three 100 watt bulbs provides 300 watts of light, enough ambient light for this room,, but it would be better spread out across the ceiling, for example, three 100 watt recessed lamps.For specific task lighting in areas where stronger light is needed, multiply the areaís square footage by 2.5 rather than 1.5 to find the needed wattage. A kitchen countertop or work island are examples of task areas in your remodeled kitchen.
Example: To adequately light a 6' x 2' countertop multiply 6 x 2 x 2.5 = 30 watts. An undercabinet fixture equivalent to a 30 watt incandescent bulb is adequate for this countertop.If you employ a lighting consultant to design the lighting for your kitchen remodel, he or she will use much more sophisticated methods, including meters that measure the amount of light falling on each surface (see the sidebar "The Best Light for Kitchen Countertops", this page, for more information), the amount of glare, and the location and duration of shadows. But, for most kitchens, this simple calculation and some common sense is all that is needed.

" the unit of illuminance and luminous emittance, measuring luminous flux per unit area."Glad we were able to clear that up for you after all these years.
