	How do I determine the size chandelier I need for over a dining room table?
	The chandelier should be approximately 12" smaller than the narrowest width of the table. It should hang so that the bottom is 30" above the table surface.

	Can I dim a low voltage system?
	Most low voltage systems can be dimmed. Remember to match your low voltage dimmer to the type of transformer (i.e. magnetic or electronic).

	What is the proper height to install wall sconces?
	They should be installed approximately 60" off the floor.

	How do I light a cove evenly?
	Using a 5-10 Watt frosted lamp xenon or halogen system with lamp spacing of 4" will create an even glow throughout the cove.

	How much light do I need for task lighting?
	20-50 footcandles

	What spacing is recommended for wall washing with recessed fixtures?
	Basic rule of thumb: the fixtures should be spaced equal to the distance they are spaced from the wall. See below for specifications. SCOOP TRIMS - 20-30" from the wall and 20-30" apart. LENSED PAR/MR16 TRIMS – 12-18" from the wall and 2' apart. A LAMP OR CF TRIMS– 2-3' from the wall and 2-3' apart.

	How do I achieve a grazing effect on textured surfaces?
	Par lamps work best when spaced 6-12" from the wall.

	Can I use recessed housing outdoors?
	Most recessed housings are damp labeled for use in porch applications.

	How many fixtures can be used on a track?
	The track will have an amp load capacity that will tell you this. FORMULA FOR CALCULATING: AMPS X VOLTAGE = WATTS Example: 20 amp capacity on track 20 amps X 120 volt = 2400 watt MAX

	How low should I hang my ceiling fan?
	The fan should hang a minimum of 7' off the floor.

	Can a ceiling fan help reduce energy costs?
	Yes, using the fan in summer can reduce your energy bill by as much as 40%, and up to 10% in the winter using less energy than a 100W light bulb.

What size fan is the right size for my room?


Up to 50 Sq	Bathroom, Hallway	29"
Up to 75 Sq Ft	Breakfast Nook	36"
Up to 100 Sq Ft	Small bedroom/Laundry	42"
Up to 400 Sq Ft	Bedroom,Family Room	50-52"
Over 400 Sq Ft	Great Room	52-54"

	What size wall bracket lantern should I use?
	The height of a lantern should be based on the height of the door. If a single side lantern is used it should be approximately one third (1/3) the height of the door. If two side lanterns are used they should each be approximately one fourth (1/4) the height of the door.

	How far above the threshold of a door should I mount my wall bracket fixture?
	The wall bracket fixture should be mounted so that the lantern is approximately 66” above the threshold of the door.

	How far can I run my cable and what size should I use?
	12 Gauge under 100' 10 Gauge under 160'

How do I calculate voltage drop?

Voltage Drop= Total Watts x Cable Length / Cable Consant


#18	1380
#16	2200
#14	3500
#12	7500
#10	11920
#8	18960

Keep the voltage drop number <1.2
Never use brass or copper fasteners in a tree.
Dip lamps in corrosive preventive compound to help prevent oxidation.
The recommended feed to each lamp is 10.8V - 11.5V
