Philmore 30-10835 — On-at-Dark Photoelectric Switch, 250W The Philmore 30-10835 is a photo-electric on-at-dark switch designed to automatically close a lighting circuit when ambient light falls below its sensing threshold. This device simplifies dusk activation for lamps and fixtures by removing the need for manual switching or timer programming, helping installers and maintenance teams save time on site. With a 250 watt switching capacity specified in the product listing, it is intended for controlling modest lighting loads where automatic dusk activation is required. The compact function and straightforward purpose make it useful for field replacement, retrofit projects, and OEM integration where a simple light-sensitive control is preferred. Because this listing uses manufacturer-provided identifiers, customers can match the part quickly for service, repair, or inventory replenishment. Installers and technicians will appreciate the predictable on-at-dark behavior when planning lighting circuits and schedules. The straightforward operation reduces configuration time and supports consistent dusk-to-night transitions for controlled lighting systems. Below are concise feature and specification notes to assist purchasing and installation decisions. Key Features: Photo-electric activation — switches on at dark Rated for 250 watt lighting loads (as listed) Specifications: Manufacturer: Philmore MPN: 30-10835 UPC: 0038975318356 Typical applications include dusk activation of exterior or interior lighting circuits, replacement of failed light sensors in lighting fixtures, and use in control panels where a basic light-sensing switch is required. The product serves field installers, low-voltage and lighting technicians, facility MRO teams, and OEM assembly processes that require automatic light sensing without programmable controls. Installation example: a service technician replacing a failed dusk sensor on a parking lot pole can swap this unit in-line with the fixture circuit to restore automatic night-time operation, verifying load compatibility with the 250W rating before power-up.
