Intermatic LC4536LAC – Frequently Asked Questions

1) Will the Intermatic LC4536LAC photocontrol fit the twist-lock receptacle on my existing area light fixture?
Yes, if the fixture has the standard 3-prong twist-lock receptacle. The LC4536LAC is a locking type photocontrol built to ANSI C136.10, which is the receptacle standard used on outdoor area lights, shoebox fixtures, and street lights. You twist it in and lock it, no wiring at the fixture. If your fixture instead has a 7-pin dimming receptacle or a stem/flush mount opening, this is not the right control.
2) Can I use one photocontrol part number across both 120V and 277V fixtures in my building?
That is exactly what the LC4536LAC is for. It accepts 120 through 277 VAC at 50/60 Hz, so the same control works on 120V wall packs and 277V commercial area lights. For a property manager or MRO buyer standardizing a stockroom, it removes the need to carry separate 120V and 208/240/277V photocells.
3) Why do my parking lot lights shut off when a car's headlights hit them, and will this photocontrol stop that?
That is a photocontrol with no time delay reacting to a passing light source. The Intermatic LC4536LAC has a delay feature specifically to prevent unwanted OFF switching from temporary light like vehicle headlights, so the fixture stays on through the pass.
4) What is the difference between a thermal photocontrol and an electronic one?
The LC4536LAC is thermal: a mechanical bimetal switch paired with a Cadmium Sulfide photocell. The CdS cell senses light, the bimetal heats and opens the contacts. Thermal units switch with a natural built-in lag, which is what gives the delay behavior against passing headlights. Electronic photocontrols switch faster and more precisely instead. If your spec calls out a thermal or bimetal type control, this is that type.
5) What does the spark arrestor on this Intermatic photocontrol actually do?
It suppresses spark formation at the contacts during switching. On a bimetal thermal control the contacts open under load every night, and arcing is what eventually burns them up. The arrestor protects the contacts and the connected fixture. Intermatic rates the LC4536LAC through 3,650 ON/OFF cycles of testing.
6) How tall is the LC4536LAC, and will it clear under a fixture shroud?
The body measures 2.75 inches in height above the twist-lock base. That is the dimension to check against any shroud, guard, or photocell cover already on the pole head.
7) Is a photocontrol like this suitable for municipal street lighting and security lighting, or only residential?
It is built for commercial and municipal outdoor lighting control: parking lots, walkways, building exteriors, security lighting, landscape and architectural lighting, street lighting, and industrial perimeter lighting. The 120-277V range and the ANSI C136.10 locking base are what make it work across those fixture types.
8) Can I identify this photocontrol on the pole without taking it down?
Yes. The LC4536LAC housing is white with a blue band, which is the visual marker crews use to tell voltage families and types apart at a glance during a maintenance sweep. Housing is high impact thermoplastic and it is made in Mexico.
