Lighting Style and Function Dilemmas Solved
The formula to find the right diameter for a chandelier in your dining room or as a focal point in an entryway or living room, is length of room + width of room, converted to inches or (12+24= 36). For this example you will need a chandelier that is 36 inches wide. You can also measure against the table too if the measurement seems a bit off. The chandelier should be three quarters of the width of the table, or 12" less than the width of your table. It should hang no lower than 30 to 32 inches from the table top, based on an 8' ceiling.
To find the number of watts you need in a space, begin by measuring the room. Once you have the room measurements, there is a simple formula to find the number of watts needed. To figure the wattage for a 12' by 24' room, multiply 12 x 24 to get the square footage, (12 x 24=288) Then multiply 288 by 1.5 to find the number of watts needed to illuminate the room. (288 x 1.5= 432) You will need 432 watts in a space to properly illuminate it. Most fixtures take 60 watt bulbs, to find the number of bulbs needed divide 432 by 60, or by the desired wattage. If you plan to use halogens, LED's or CFL's you will need to determine the comparable wattage as they typically differ fromÂ incandescentÂ bulbs.Pendants should be hung at 30" above the counter top with the light hitting the counter and not the floor. Multiple pendants should be hung evenly spaced over the the island as well.
