Dayton 26WA90 Incandescent Photocontrol 1800W Black
Controls outdoor lighting from dusk to dawn with a 1,800 W incandescent capacity and raintight polycarbonate housing
- Automatic dusk-to-dawn lighting control
- Handles up to 1,800 W incandescent loads
- Raintight polycarbonate housing rated for -40 °F to 158 °F
- UL Listed for safety compliance
- Simple 1/2 in conduit flush mounting with included hardware
Purpose and User
The Dayton 26WA90 is a dusk-to-dawn photocontrol designed for outdoor lighting circuits up to 1,800 W. It serves electricians and facility managers who need automatic on-off switching for incandescent or ballast loads without manual timers.
Sustained Operation
The unit activates between 10.0 and 20.0 foot-candles and deactivates between 30 and 60 foot-candles, providing a hysteresis band that prevents cycling under changing twilight conditions. Rated for 15 A incandescent and 9.2 A ballast at 120 V AC, it handles continuous loads within those limits across a -40 to 158 degrees F ambient range.
Build and Connections
A polycarbonate housing with a raintight enclosure protects the SPST contacts from moisture and debris. The 1/2 in conduit mounting includes a lock nut and washer gasket for a secure, sealed flush installation on junction boxes or fixture knockouts. UL Listed construction confirms compliance with applicable safety standards.

Questions about this item
How much heat does the 15 A incandescent rating generate during all-day operation?
The unit is rated for 15 A incandescent and 9.2 A ballast loads at 120 V AC; its polycarbonate housing and raintight enclosure are designed to dissipate heat within the -40 °F to 158 °F operating range.
What wiring and conduit must I already have to install the 1/2 in conduit mounting?
You need a 1/2 in conduit opening, a lock nut, and a washer gasket — all included — plus 120 V AC supply wires sized for up to 15 A incandescent or 9.2 A ballast circuits.
Will the 10.0 to 20.0 foot-candle turn-on threshold work with older fixtures that use lower-wattage lamps?
Yes, the SPST contact switches at 10.0–20.0 fc on and 30–60 fc off, so any 120 V fixture drawing up to 1,800 W incandescent or the rated ballast amperage will operate correctly.
