ALR branded Photocontrols, Timers, and Lighting Accessories are designed and approved to meet all commercial, industrial, and utility requirements.

BF Series - Industrial/Commercial Grade
The BF series locking-type photocontrols are engineered to meet the needs of virtually every commercial and industrial outdoor lighting control application utilizing HID luminaires equipped with locking-style receptacles. Typical applications include parking lots, security lighting, street, and other types of area lighting. The heavy-duty thermal bi-metal switch produces a minimum 30-45 second time delay, eliminating unwanted off/on operations that could be caused by lightning, car headlights, or other sudden changes in the ambient light level. BF controls are also equipped with a 180 joule MOV to protect both the photocontrol and the luminaire from sudden surges in the l ine voltage. 
 
LC Series - Residential Grade
The LC series locking-type photocontrols offer an economical and cost-effective means of controlling residential lighting systems from dusk to dawn. These controls feature a heavy-duty bi-metal switch that produces a minimum 30-45 second time delay, virtually eliminating unwanted off/on operations that could result from lightning, car headlights, or other sudden changes in the ambient outdoor light level. LC controls are a perfect and reliable solution for lighting driveways, patios, decks, entryways or other areas around the home where security lighting is desired. 
 
M Series - Industrial Grade
The M series photocontrols are engineered to meet the demanding needs of Utility street lighting control. The heavy-duty thermal bi-metal switch in the M series produces a minimum 30-45 second time delay, eliminating unwanted off/on operations that could be caused by lightning, car headlights or other sudden changes in the ambient light. This feature makes the M series well suited for areas with high lightning activity. All M series controls are equipped with a Metal Oxide Varistor (MOV) to protect both the control and the luminaire against sudden surges in the line voltage, as well as a 1" CdS cell to maximize the photocontrol’s useful life.
