What this product is for
The Intermatic EK4136S is a stem-mount electronic photocontrol used to switch exterior lighting on at dusk and off at dawn based on ambient light. It is intended for commercial, industrial, and multi-voltage outdoor lighting applications where automatic control helps reduce unnecessary run time.
Use for
Use for wall packs, area lights, building perimeter lighting, sign lighting, security lighting, and other outdoor luminaires on 120-277V circuits. It is commonly selected where electricians need one photocontrol that can cover 120V, 208V, 240V, and 277V installations.
Avoid for
Avoid using this photocontrol where the connected load exceeds its published ratings, where a twist-lock receptacle style photocell is required, or where the fixture location causes false triggering from reflected light. It is also not the right choice when a programmable timer or networked lighting control is required instead of simple dusk-to-dawn operation.
Best for
Best for contractors replacing failed fixture-mounted photocells on commercial exterior lights, especially in parking areas, walkways, loading areas, and building exteriors. The built-in time delay helps prevent nuisance cycling from lightning, vehicle headlights, or other brief light changes.
Installed in
Typically installed on outdoor luminaires and junction-box or fixture-mounted stem openings. The housing is approximately 2.25 in H x 1.3 in W x 1.24 in D (57 x 33 x 31 mm), which helps when checking fixture clearance before ordering.
Why this product exists
This product provides simple automatic lighting control without requiring a separate timer or building control system. For many exterior lighting jobs, a photocontrol is the straightforward way to improve energy use and keep lights operating only when ambient light levels call for it.
Compared with similar products
Compared with thermal photocells, this electronic model is designed for more stable switching and broader compatibility across modern lighting loads. Compared with receptacle-type photocells, a stem-mount unit is commonly used where the fixture is built for direct fixture or box mounting. As typical guidance, photocontrols like this are often chosen for straightforward dusk-to-dawn control rather than scheduled shutoff strategies; actual control performance depends on fixture placement, aiming, surrounding light, and local electrical code.
