Intermatic Leads the Charge in Bringing Proven LED Compatible and LED Sustainable Controls to Market

How can electricians be sure about what controls to use with LED lamps?

At Intermatic, we’ve focused on developing and implementing a rigid, robust testing approach in our UL-recognized laboratory to give contractors and distributors the clarity they need. For years electricians have used Intermatic controls with older technology lamps like CFLs and fluorescents. We often get asked if those controls can work with LED lamps as well.

Since there is no single industry standard for testing controls used for LED lighting, we took the best information from NEMA 410 and UL standards, and combined these into a testing scenario for all Intermatic products – including our long standing products –  that could show true performance with LED drivers. Here is how we did it:

  • Simulated actual field performance for the life of LED lamps
  • Used repeatable test case scenarios
  • Put our traditional controls through thousands of on/off cycles to ensure our whole portfolio of new and old controls are not only LED-compatible, but that they mirror the life expectancy of LED fixtures

See our chart below for details.

Intermatic is a 124 year old US owned company focused on simple, affordable energy controls for today's electrical pro. We succeed when you do.
