Intermatic LC4536C – Frequently Asked Questions

1) Will the Intermatic LC4536C photocontrol fit the twist-lock receptacle on my existing parking lot fixture?
If the fixture has an ANSI C136.10 NEMA twist-lock receptacle, yes. The LC4536C is a locking-type plug photocontrol built to ANSI C136.10, which is the three-prong twist-lock socket found on the top of most outdoor area, roadway and wall-pack fixtures. It plugs in and twists to lock, so swapping a failed control takes no wiring. Fixtures with hardwired photocell leads or a stem-mount cell are not a match.
2) Can one photocontrol cover both 120V and 277V fixtures across a site?
Yes. The LC4536C accepts 120-277 VAC at 50/60 Hz, so the same part works on 120V residential-style circuits and on 277V commercial lighting branch circuits. For a property manager or MRO buyer that means one stock number on the shelf instead of separate 120V and 277V controls for different buildings.
3) Will headlights or lightning make this photocontrol shut the lights off at night?
No. The Intermatic LC4536C thermal photocontrol has a delay feature that prevents unwanted OFF switching during brief light interruptions, so passing headlights, a camera flash or lightning won't drop the fixture. That also cuts needless cycling, which is what shortens lamp life on street and parking lot runs.
4) Thermal photocontrol or electronic photocontrol for outdoor area lighting?
The LC4536C is the thermal type: a mechanical bimetal switch triggered by a cadmium sulfide photocell. The bimetal element gives it an inherent turn-on delay and thermal protection, and it is rated for 3,650 ON/OFF cycles, which works out to roughly ten years of one cycle per night. Electronic photocontrols switch with solid state components instead and generally offer longer cycle life and tighter turn-on levels. If you're maintaining HID or standard outdoor fixtures on a straightforward dusk-to-dawn schedule, the thermal unit is the conventional choice; for heavy-cycling or dimming-capable LED systems, look at an electronic control.
5) Do I need any extra hardware or wiring to install this photocontrol?
Nothing extra if the fixture already has the receptacle. The locking plug design means installation and changeover is plug-and-twist on an ANSI C136.10 NEMA socket, with no wire nuts, no conduit work and no tools. If the fixture has no twist-lock receptacle, you would need to add a photocontrol receptacle to the fixture first, which is a separate part.
6) How much clearance do I need above the fixture to install the LC4536C?
Allow at least 2.75 inches of vertical clearance above the receptacle. That is the stated height of the photocontrol body, and it sits proud of the fixture top once twisted into the socket. Worth checking on pole fixtures mounted tight under a canopy or a decorative shroud.
7) Is this photocontrol rated to sit outside in the weather?
It is built for outdoor lighting control. The LC4536C uses an integral high impact thermoplastic enclosure that protects the photocell and bimetal switch from the elements, and when twist-locked into an ANSI C136.10 receptacle the plug interface seats against the fixture top. It is intended for pole-mounted area lights, wall packs, perimeter and walkway fixtures.
8) How do I tell the LC4536C apart from other Intermatic photocontrols on the truck?
Look at the band. The LC4536C housing is white with a blue band, and the label reads LC4536C. Intermatic uses the band color to separate models, so the blue band is the quick visual check when you're matching a replacement to what's already on the fixtures.
