MEASURE LAMP DEGRADATION?
In order to receive an accurate measurement of a lamps degradation, one should take an average reading of the tanning lamps as soon as they are installed in their bed. The actual number is not important, it is merely a starting point. Periodically, you should check your lamps with the meter. We recommend that lamps be replaced when they have decreased in performance by 30%. The following factors affect the accuracy of a lamp meter: calibration, incoming voltage, the distance between the lamp and the meter, and the location of each reading (measured in three different locations on the lamp) and the time of day the readings are taken.
