Does anyone have the main lights on a occupancy or proximity sensor to activate when someone pulls into the property?
I replaced all the MH and fluorescent fixtures in my 8 bays in 2016. Two fixtures per bay with three 4’ LED tube lamps each. I powered each fixture with 2 circuits, home run to the lighting control panel.
Operation is controlled by an IDEC SmartRelay with built-in astronomical clock.
- All lamps ON 30 minutes before dusk.
- At 10:00PM – 2 lamps OFF in each fixture for 6 bays…(the bays on either side of the equipment room remain fully illuminated.)
- Should a customer use one of the dimmed bays, all lamps ON in that bay.…(timed output signal from the meter box timer). Lamps remain ON for 15 minutes after time expires.
- All lamps OFF 30 minutes after dawn.
I calculated the lamp life expectancy for dusk-to-dawn operation to be ~13 years.
I sold the wash later that year. As of December 2021, my attendant, who retained his job, stated that he hasn’t replaced any lamp. He thanked me for the reduction in lighting maintenance. He also shared that morning clean-up in the 6 dimly lit bays had been greatly reduced.
