Two operating characteristics of
fluorescent lamps are efficacy and lumen maintenance. Name three others.....
MORTALITY..COLOUR RENDERING ...ENVIRONMENTAL CONSIDERATIONS::.
-
Efficacy defines light output per
unit of
POWER input.
-
Why is efficacy an important
characteristic?
ELECTRICITY CONSUMPTION IS NORMALLY THE MAJOR OPERATING COST...
-
Fluorescent lamp efficacies are
typically
3-7 times higher than incandescent lamps.
-
Calculate the efficacy of 1200mm
36W Polylux 840 lamp.
________3450/36 = 95.8 LW_________
-
The optimum temperature range for
fluorescent lamps is . .
___________5-25 DEGREES CELSIUS_________
-
Fluorescent lamps using high
frequency electronic ballasts have higher lamp efficacy.
