King Apollo 6 450w LED Grow Light Full Spectrum 10 band 380-730nm For Indoor Plants Hydroponic System Grow and Flower Use 3W high quality LED lighting source, the lifespan is over 50000 hours. High lighting effect, 90% of the light will be absorbed by the aquatic plant, but to the traditional HPSL and MHL, the lighting effect is just 8%~10%. The input voltage is AC100V~240Vsuitable for the world standard. Built-in power supply. No need other equipment, just access AC100~240V voltage from the plug, the lamp will be working smoothly, don't need the reflector and ballast either. Revolutionary heat dissipation design, availably alleviate the internal thermal cycle, 10-15 lower than its precursor in performance. Using advanced isolated power driver, UL standard output voltage which is lower than 45V DC.Soft starting protection to avoid the transient currents impact, effectively protecting the LEDs from high voltage damage.
