In this way, the heat generated by every single light quickly dissipated through the heat column, ensure timely cooling. TheLED Light integral heat sink is conducting all lamp beads to produce aluminum plate, and then disseminated through the radiator, cooling at a slower pace. The LED Bulb size of the radiator, the quality of aluminum affects the heat dissipates speed, and also affects the price of the entire lamp. 2, the lamp power supply (commonly known as the transformer): Transformer quality also determines the life of the whole lamp, lamp beads used for more than 50,000 hours is no problem, but if the transformer is broken, then the whole lights cannot bright. myledgrowupanty 141023
