BTW, if you want to calculate lamp cost per session, multiply the bed cost per minute by number of minutes of a session.

For example, a $10.00 lamp that lasts 700 hours in a 32 lamp bed will have a single lamp cost per minute of about 0.024 cents per minute per lamp, or .76 cents per minute for the whole bed. A 20 minute session will cost about 15 cents in lamp costs.
