• When circuiting lighting plans
always print the lighting plans

• Keep all lights on the same
circuits, adjacent to each other

• For T8 & T5 Fluorescent Lamps use the total Lamp Wattage
• i.e. If you have (2) 32W T8 lamps use 64W
• Fluorescent Ballast factor can vary from .76 to 1.18
• BALLASTS SHALL BE INSTANT START, ELECTRONIC TYPE, CLASS P, "A"
SOUND RATING AND MAXIMUM HARMONIC CONTENT OF 10%
• DIMMING BALLASTS SHALL BE 3-WIRE TYPE, WITH DIMMING
CAPABILITY TO 10% OF RATED FULL OUTPUT
• ALL FIXTURE / BALLAST / LAMP COMBINATIONS SHALL BE ENERGY
SAVING TYPE

• GE 3 Lamp Ballast type 23673-GE-332 with 3 lamps the total fixture
wattage is 85W. 11W less
• Same Ballast with 2 lamps is 65W. 1W more
• GE 4 Lamp Ballast type 23675-GE-432 with 3 lamps the total fixture
wattage is 113W. 15W less
• Same Ballast with 3 lamps is 97W. 1W more
• Two level switching fixture with (2) ballasts [ 2-lamps and 1-lamp] total
wattage is 61+36= 97W
• To be safe use the total Lamp Wattage

• For CFL use the fixture wattage +4W. I.e. fixture with (2) 16W use
18+18+4= 40W
• Except the 42W CFL add 5W
• GE CFL13W 1 lamp fixture with 87533-GE1CFL13PH total system
wattage is 16W
• GE CFL42W 1 lamp fixture with 87573-GE1CFL42PH total system
wattage is 47W

• For traditional incandescent Lamps like types A, use the Wattage of the
Lamp
• For low voltage MR16 lamps add 10% for ballast factors

• For LED fixtures:
• If the driver is built-in, the total fixture wattage is what the
manufacturer advertised, per IEC and DOE standard
• For remote driver fixtures and fixtures where the EC has to provide a
step down 24V transformer, add the LED wattage and driver
efficiency
