fluorescent lamp. In many cases, replacement of the reflector is also required to
efficiently utilize the compact fluorescent lamp. Verify that the lamp length is compatible
with the can depth. Compact fluorescent lamp watts should be about 25 percent to 30
percent of original incandescent lamp watts to achieve similar light levels.
F-16.3.2 Atypical Installa tions. In some cases, hardwired conversions can be
difficult or not cost effective. Use a medium based adapter with integral ballast and
replaceable lamp. Compact fluorescent lamp watts should be about 25 percent to 30
percent of original incandescent lamp watts to achieve similar light levels.
F-16.4
Existing Fluorescent Industrial Luminaires, Wraparounds, and Strip
Lights.
F-16.4.1 Replace F40T12, and F48T12 lamps and magnetic ballasts with T-8 lamps and
electronic high frequency ballasts. Consider employing reflectors and low ballast factor
ballasts to achieve further energy reductions.
F-16.4.2 For lighting systems employing F96T12 slimline and F96T12/HO lamps,
consider all of the following:
Retrofitting with electronic high frequency ballasts and continuing to use existing
lamps.
Replacing 2.4 meter (8 foot) lamps with 1.2 meter (4 foot) T-8 lamps, possibly
including high light output ballasts and/or high output T-8 lamps when replacing
T12/HO lamps.
Replacing 2.4 meter (8 foot) lamps with T-8 2.4 meter (8 foot) lamps and electronic
high frequency ballasts.
F-16.5
Existing HID Industrials, Floodlights, Downlights and Other Luminaires.
F-16.5.1 Replace mercury vapor lighting systems with one of the following approaches:
Replace mercury vapor lamps with compatible metal halide or high-pressure sodium
lamps, especially if increased light levels are required.
Retrofit with metal halide ballasts and lamps for work spaces and other spaces
where color rendering is important. The metal halide lamp s hould be about 60
percent of the original mercury vapor watts.
Retrofit with high-pressure sodium ballasts and lamps for storage spaces and other
spaces where color rendering is not important. The high-pressure sodium lamp
should be about 50 percent of the original mercury vapor watts.
Replace with a compact fluorescent luminaire of similar type, especially for low
wattage mercury vapor lamps (up to 100 watts). This replacement is especially
