What is Bi-Level Lighting?
Allows the user to choose between two OR three levels of light
The levels can be either 33%, 66%, and 100% or 50% and 100% depending on how it’s wired
Consists of two switches
What is Bi-Level Lighting? (cont.)
On a 33%, 66%, 100% circuit… One switch turns on 33% light The other switch turns on 66% light Both switches for 100% lighting
On a 50%, 100% circuit… Each switch turns on 50% light Both together turn on 100%
How does it work?

How much money can I save?
Savings up to 50% Average of $100 annual saving per office
ROI within two years Why so long?
Depends on amount of money spent on switches
Switches
Can you really tell a difference?
Yes, if your in the room while you flip the switch
This can be solved by having the light go on when you walk into the room
Most of the time people assume that they are on full
Money savings vs. energy savings
