Light Emitting Diodes (LEDs) have several advantages over traditional lighting like significantly longer lifespan, superior spectral output with good color rendering ability, higher efficiency and lower energy consumption but need reliable protecting to maintain and enhance performance and longevity - especially in outdoor LED lighting applications. Combining protection from harsh weather cycles, long-term UV exposure and mechanical stresses with features that improve health like resistance to fungus growth or low outgassing in one product extends the life of the LED. Whether you are looking to solve needs in outdoor LED lighting applications on streets, highways, parks and recreation areas or indoor in gas stations and commercial buildings, we have the silicone gasketing solutions of choice designed for the demanding, long-term nature of your requirements.
