Diode Dynamc DD0483P Limited Lifetime Warranty
The SL2 Pro features new thermal separation technology (TST) LED's. Unlike a traditional LED chip, TST LEDs are designed with electrical connections on the top. This means the entire bottom surface of the LED can be dedicated to channeling thermal energy out and away from the LED. This lowers thermal resistance, allowing the SL2 Pro to run at higher power levels than traditional LED bulbs, while maintaining focus. The SL2 Pro features an integrated top-mounted fan for superior thermal management and reliability. Since the fan is sealed inside the housing, there's no concerns about damage from dust or moisture over time and with the fan on the top of the bulb, the cooling happens right next to the LEDs - the source of the heat. The SL2 Pro was put through its paces in our environmental testing chambers - where the bulb lasted through repeated thermal cycles from -40 through 85 Degrees Celsius (-40 to 185F), along with a range of other environmental tests. It's also designed with transient protection, to prevent premature failure from electrical spikes in the vehicle.
