LED Cooling Solution

The life span of an LED depends on the semi conductor material used as well as the current/heat relationship. The light output of the LED becomes weaker and weaker if proper Thermal grease and Heat Sink is not applied once it reaches 50% of its initial value, the life expectancy of the LED is maintained by applying good Thermal Grease and Heat Sink

Addition Driver Required

The LED drivers provide protection to the LED bulbs against current and voltage fluctuations. The drivers ensure that the voltage and current to the LED bulbs remains within the operating range of the LEDs regardless of fluctuations in the mains supply.


  • Power : 50W
  • Voltage : DC36-60V
  • Current : 900mA

Pure Aluminum Base

In particular, Aluminum is widely used in LED die interconnects due to its low electrical resistance and long term stability against environmental degradation.
