Light shield for EK4036S, EK4336S, and K4000C Series photocontrols, used to adjust turn on / turn off sensitivity or alleviate nuisance cycling due to light feedback.

The adoption of LED lighting continues at a rapid pace, presenting a compatibility challenge with older technology controls, especially outdoor photocontrols. This technology white paper suggests solutions to address the high-current transients delivered by electronic ballasts.

The need to get the installation industry comfortable with the [LED] technology motivated Intermatic Inc., Spring Grove, IL, to develop a comprehensive new testing approach to help inform electrical contractors of the performance of its lighting control portfolio when LED lighting is used.

New Product Highlights


The Intermatic® line of occupancy sensors are engineered and tested for long-lasting performance. In-Wall and Ceiling Mount sensors in both PIR (infrared) and dual (PIR/ultrasonic) technologies can monitor virtually any area within a building, providing solutions for any retrofit or new construction project. They utilize zero-crossing technology to suppress inrush current impact, supplying reliable ON/OFF sensing no matter the lighting technology.


The Intermatic® ICUBE™ Adaptive Defrost Module cuts defrost cycles--and utility bills--for the food service industry. Designed by Grässlin by Intermatic for commercial walk-in coolers and freezers, the smart-sensing technology behind the ICUBE™ continuously monitors evaporator coil temperatures and only allows defrosting when necessary at the next programmed timer interval.

Surge Protective Device Group Shot

The Intermatic® Surge Protective Device with Consumable Modules covers 100% of a home’s big investment equipment, from appliances and computers, to HVAC equipment and TVs. The Surge Protective Device uses replaceable Consumable Modules that allows homeowners to easily and safely replace a module when the built-in LED light indicates it has been compromised.
