Yes, fluorescent lamps contain mercury. Please dispose of according to federal, state, and local regulations.

No! This type of power supply is actually a DC battery with a circuit that imitates AC voltage. It will damage the electronic ballasts used for the fluorescent lamps.

The simplest way is to determine how much time the booth is used each day then divide that time into the total rated hours for the daylight source (2500 hours). As an example, if the booth is used 2 hours each day (on average) the booth should be relamped in approximately 3.4 years (2500 ÷ 2 = 1250 ÷ 365 = 3.4 years).

No. It tracks the amount of time the Primary source is used so relamping schedules can be properly maintained.

Yes. The hour meter only tracks the usage of the Daylight source. It is generally considered the most important source for evaluation and color matching applications.
