Light Timers
A bit of progress on the lights. This photo shows the bottom of a wall shelf that holds the three dual MH ballasts and the three wall-mounted timers that control all the lights. One timer is going to do the T5's, the 2nd does 2 of the MH ballasts, and the third does the third MH ballast.
***update 04/10*** After 3 years, the timer responsible for 2 of the MH began to fail intermittantly such that it would NOT shut the lights off properly. That Intermatic (now GE) timer was not rated to handle the load of 4 x 250W MH and has since been replaced with a more industrial timer with mechanical switching.   There are two dedicated electrical circuits there. One circuit has 2 x 250W MH + 6 x 54W T5....the other circuit has 4 x 250W MH only. Cool, you can almost read my labels... Notice that three timers are synchronized...Yes, I admit I have a problem.
