2 Pack 50W LED Chip EcoSuma Natural White 4000 Kelvin High Power LED Chips Perfectly Suitable For White Skin (50) The light chip is 4000K color temperature, equivalent to the morning or evening sunshine, Perfectly suitable for white skin. While 6000k color temperature turns to be a bit blue, skin will be more white emit on the white people. The LED light Chip is the real 50 Watt power, input 1750mA current, under the condition of good heat dissipation, lifespan will be more than 50000 hours. Use of Unique way of semiconductor packaging, Vibration resistant, Better anti-static ability Need LED driver power to light up the LED chip, input DC 30-34V, 1750mAh current. It need aluminum or copper material for LED heat dissipation, and need to put the thermal conductive silicone evenly between the radiator and light source, similar to the computer's CPU and radiator, LED light chip need heat conduction while you light it up, otherwise the service lifespan of LED light chip will be very shortened or burned.
