As LED fixtures produce light, they also produce heat. The higher the wattage the greater the heat. The thermal management system in the fixture pulls the heat away from the LEDs and dissipates it, so that the heat-sensitive diodes do not fail prematurely.
A passive technology called a heat sink is typically used to absorb unwanted heat, but, there is a tremendous difference in the size and quality of heat sinks used in grow lighting. If the heat sink is poorly constructed, a motorized fan is often added to the fixture to assist in cooling it down.
Unfortunately, motorized fans are poorly suited to survive the conditions of a grow operation. The accessible vents and whirring blades are vulnerable to the bugs, dirt, water, debris and chemicals commonly found in the space. Fixtures with motorized fans translate to more potential points of failure. If the motor or fan is damaged or unable to effectively cool the fixture, the LEDs are likely to overheat and fail, exposing an operation to down time that may compromise the crop. Avoid these potential pitfalls by selecting a grow fixture that uses a 100% passive thermal management system.
All SpecGrade LED grow lights are equipped with a proprietary, high-performance passive thermal management system engineered to operate flawlessly in extreme grow conditions. The high-quality heat sink features over 75 feet of double-folded aluminum fins that effectively dissipate the heat from the LEDs, without assistance from a fan. Enjoy the low maintenance benefits of reliable thermal management with SpecGrade LED.
