Photocontrol for Dusk-to-Dawn Lighting

The Intermatic LC4523 is a turn-lock photocontrol designed to automate outdoor and industrial lighting circuits from dusk until dawn. It suits electricians and facility managers who need reliable on-off switching for HID or incandescent loads up to 4,150 watts on 208 to 277 volt AC supplies.

Sustained Operation in Harsh Environments

The raintight polypropylene enclosure protects internal contacts across a temperature range of -20 to 104 degrees Fahrenheit, allowing continuous outdoor exposure without degradation. A 90-second time delay prevents false triggering from brief light changes, while the SPST contact form handles up to 15 amps incandescent or 8.3 amps ballast load through repeated daily cycles.

0.5 Foot-Candle Activation Threshold

The control switches on when ambient light falls to 0.5 foot-candles and switches off at 15 foot-candles, a fixed sensitivity that determines whether the unit matches the specific site lighting design. Buyers who need adjustable sensitivity or a different voltage range must select another model.

Questions about this item

Does the Intermatic LC4523 generate noticeable heat or consume power continuously during all-day operation?

The photocontrol draws minimal standby power to operate its sensing circuit and relay; the polycarbonate housing remains within the rated -20 to 104 °F ambient range during normal dusk-to-dawn cycling.

What voltage supply and wiring configuration must already exist for the LC4523 to function?

A 208 to 277 V AC circuit with a turn-lock mounting receptacle is required; the SPST contact switches the load directly at up to 15 A incandescent or 8.3 A ballast.

Will this 4150 W photocontrol work alongside older HID or incandescent fixtures already on the same circuit?

Yes — it handles up to 4150 W total, compatible with both HID ballasts and incandescent lamps through the same SPST output.
