Q: How do I determine the proper size chandelier for a dining table?

A: Choose a chandelier with a diameter half the width of the table. It should be hung with the bottom of the fixture 30” above the tabletop for an 8’ ceiling. Go up 3” for each additional foot of ceiling.


Q: How do I determine the proper size chandelier for the foyer?

A: Simply add the room dimension together. For example, if your foyer is 12’ by 16’, add 12 plus 16 to get 28. The proper size chandelier would then be 28” in diameter. This works for any room. Make sure the bottom of the fixture does not hang more than 7’ from the floor. If windows are present, center the fixture in the window so it can be seen outside.


Q: How do I determine the correct amount of wattage to properly illuminate a 12’ by 16’ room?

A: Multiply the room dimensions to get your total square footage (12x16 =192). Then multiply the square footage by 1.5 for total illumination needed. (192x1.5 = 288 watts). So, for a 12x16 room, two 150-watt table or floor lamps would give more than ample light, as would an 8-light chandelier with 40-watt bulbs. For specific task lighting within a space – for instance, the light needed on an island in your kitchen – multiply the square footage of the island (8x4 = 32 sq. ft.) times 2.5=80 watts. Two 40-watt pendants would do the job.


Q: How much light is needed in a kitchen?

A: Depends on the size. If it’s less than 100 sq. ft., a 2-light decorative fluorescent fixture is fine. Larger kitchens up to 250 feet will need a 4-light fluorescent fixture. Over 250 sq. ft. will need the 4-light plus additional supplemental lighting. Undercabinet lighting is always appropriate for task lighting of work surfaces.


Q: What’s the proper height to install wall sconces?

A: Sconces should be installed 60” from the floor. To illuminate an entire hallway, they should be placed eight to ten feet apart.


Q: Is there a rule for lighting a desktop?

A: Light sources on the desk should be approximately 16” above the work surface and approximately 13” from the desk front.


Q: In what area should I use semi-flush fixtures? What is their purpose?

A: The ceiling height, the area, and the physical dimensions of a room will determine the fixtures that should be used. Semi-flush fixtures provide unique styles on low ceiling applications. Semi-flush fixtures that are not fully enclosed also offer the appearance of more light due to reflection off of the ceiling.


Q: How can I get optimal lighting in my bathroom?

A: Avoid shadows on your face with fixtures that use incandescent bulbs behind diffusers. These radiate the most flattering light and color. Position sconces on both sides of the mirror at least 28” apart and 60” above the floor to fully surround your face with light, install a fixture that is 24” wide over the mirror as well. Add a ceiling fixture to balance the light throughout the room.


Q: What are the differences between line voltage and low voltage?

A: Line voltage is wired directly to your home’s 120 volt electrical system. Low voltage needs a transformer to convert regular household current from 120 volt to 12 volt.


Q: What size outdoor lantern do I need on my house?

A: You should think of the location from which the fixtures will be seen. While providing safety and security, front lanterns mainly add to the dιcor and presentation of your house. So the best viewing position is from the street. If the lantern is too small, it may get lost on the huge expanse of the house front. Also, think about the position of the fixtures in relation to the outlet box – does it need to project upwards or does it need to hang with the majority of the fixture below the junction level? The normal mounting height is 66” above the ground, slightly above eye level.


Q: When should I use a dimmer switch?

A: A dimmer switch can be used with any decorative lighting fixture, such as chandeliers, pendants, or even bath lights. Use brighter lighting for parties while dimming down for a quieter, more intimate setting. In addition to setting the right mood dimming can significantly extend the life of incandescent bulbs. Keep in mind that if you want to dim low voltage fixtures, you may need a special dimmer.


Q: When do I use portable lamps in a room?

A: In addition to a decorative touch, portable lamps should be used where additional task lighting is needed. The bottom of the lampshade for either a floor or table lamp should normally be 42” from the floor.
