SANSI 600-Watt Equivalence White Full Spectrum 4-Head Gooseneck LED, 40-Watt Grow Light 4000K Daylight Clip-On High PPFD Plant

360° Gooseneck and Full Spectrum: Makes every plant covered by 360° surrounding light, actualizes a more ideal full life cycle full spectrum supplementary light program, covering the entire visible spectrum of 400 nm to 780 nm, 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. Chip on Ceramic, SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink and directly solder the LED chip on the ceramic heat sink, effectively reducing the systematic 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.
