Featuring a warm white output that outperforms a 20W halogen without producing nearly as much heat, this is the perfect solution for areas that can't get enough light. The technology in this bulb includes our constant-current chipset combined with the latest 2835 format LEDs encased in a thermally conductive aluminum shell. At 100 lumens per Watt, this is one of the most efficacious products that we offer.
We recommend that this bulb be used in open fixtures, or larger fixtures which have a large enough area inside to handle a bulb this powerful to avoid overheating. The lamp itself is designed as a heat sink, but must have sufficient air around it to convect the heat away from the bulb. The lamp includes a thermal foldback feature which protects the LEDs from overheating which prolongs the lifespan in inappropriate fixtures.
