CLS EK4236S Pro-Grade Stem & Swivel Electronic Photocontrol (120-277V)

Most landscape lighting systems should come on at dusk and go off at dawn without anyone touching a switch, and a photocontrol is the simplest way to make that happen. The CLS EK4236S is an electronic stem and swivel photocontrol rated for 120 to 277V AC, built for lighting circuits that need dependable light sensing year after year.

Why does the swivel mount matter on a photocontrol?

A photocell only works as well as the sky it can see. The stem mount swivels through 180 degrees, so you can turn the sensor away from the fixtures it controls and away from porch or street lights, toward open sky, even when the enclosure sits in an awkward corner.

How much load can one EK4236S switch?

CLS rates it for single or multifixture HID and LED loads up to 1,650 W at 277 VAC. On most landscape jobs that leaves comfortable margin for one photocontrol per transformer or lighting circuit.

What keeps it from drifting or wearing out early?

The sensor is a non-drift silicon cell behind an IR filter, so the switching point holds steady instead of creeping over time. Switching runs through a DC relay with zero-crossing circuitry to reduce stress on the contacts, and CLS rates it beyond 10,000 on/off cycles. The circuit board is conformal coated against moisture, and an MOV element adds surge protection.
