SANSI LED Grow Lights for Indoor Plants 600W Full Spectrum Clip-on Gooseneck40W Plant Light High PPFD Lifetime Free Bulbs Replacement White+Puck Grow Light 10W (150 Watt Equiv) 2-Head Grow Lamp

- THE SECONDARY OPTICAL DESIGN: PPFD: 804 μmol/s/㎡@1ft. Through the lens for secondary scientific light distribution, improves light utilization, giving plants more supplementary light. Using only 40 watt of power, equivalent to 600W incandescent bulbs. Based on 18 hours per day usage, save up to 90 percent electricity - PATENTED CERAMIC TECHNOLOGY: Chip on Ceramic, SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, and directly solders the LED chip on the ceramic heat sink, effectively reducing the system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, producing a SANSI bulb with higher light efficiency - PATENTED CERAMIC TECHNOLOGY: Chip on Ceramic, SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, and directly solders the LED chip on the ceramic heat sink, effectively reducing the system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, producing a SANSI bulb with higher light efficiency - 360 DEGREES GOOSENECK AND FULL SPECTRUM: Making every plant covered by 360 degrees surrounding light, actualize a more ideal full life cycle full spectrum supplementary light program, covering the entire visible spectrum of 400nm-780nm, suitable for every cycle of plant growth, effectively promote plant growth, and improves crop yield and quality. Providing 4000K daylight, color rendering index Ra is close to 100, infinitely close to natural light - GUARANTEES: ETL listed certification, quality and safety verified, 25,000 hours lifespan for the bulb. Attention Please: The maximum safety wattage rating is 10 watt for each head
