New York City (High-End Residential):
The client wanted to illuminate 36 drawers with 24-volt DC-LED linear lights in her dressing room. The electrician used the recessed (GRI 3030-T) low-voltage door jamb switches to turn on and off the lights. That would require 36 REMCON relays and 36 LED drivers as well to be able to control each lighting zone individually.
We were providing three 12-zone lighting control relay panels with three LED drivers instead.
The relay panels are controlling the secondary side (24 volts) of the LED drivers, that’s why one driver was enough for 12 lighting zones.
The control panels alongside the led drivers were installed in the mechanical closet (about 50 feet from the beginning of the lighting fixtures) to ensure easy access for maintenance and to meet the requirements of the National Electrical Codes.
Conclusion:
It would be such a waste of time and money to install 36 LED drivers (plus 36 REMCON relays) when 3 LED drivers are enough to energize all lighting zones.
