SZHLUX 400W LED Grow Light 4x4ft with Timer and Temp Control, Full Spectrum Grow Lamp with 864 Diodes for Indoor Plants, Sunlight Plant Light for Seedling Veg and Bloom Grow Light. High Efficiency and Low Energy Consumption? - SZHLUX PT LED Grow Lights utilize the latest in high yielding LEDs technology diodes, high Energy Efficiency with 2.9 Umol/J, delivers powerful light output and uniform canopy penetration to resulting maximum higher yields. Actual power is 400W with 864 LEDS, effective footprint is 4 x 4 ft. Temp Control and Timer Modes?

- Upgraded PT series with temp sensor, temp button and timer button. The light hanging height can be adjusted properly, plants will get more PPF value, no more electricity will be wasted. Auto setting Temp is 85? ; When temperature is up to 86?

7 light bars on; When temperature is up to 91? 5 light bars on; When temperature is up to 96? The light would be turned off.

- Infinite close to sunlight wave for plants, over 95% light energy can be absorbed by plants. White, blue, red and IR (3000K, 5000K, 660nm and IR 730nm).

3000K providing more reddish light and the 5000K providing more blueish. Especially 5000k blue light promotes seedling growth, the 660nm red and 730nm IR light is most useful for plant photosynthesis, promote plant flowering and fruiting, increase yield and crop quality. Trapezoid Tube and Fanless Design? - Original Factory innovation designed Trapezoid-shape Led Tube for larger luminous area than T5 and T8 led tube. Premium aluminum shell with fanless design for faster dissipation speed, make your growing life easy and quiet, allowing your plants receive more energy and without burning.

- Larger light costs about half for HPS light, our upgraded PT series adopt the latest drive with temperature control and timing design button instead of traditional dimming knob, more scientifically designed for the whole stages of plant growth.
