SANSI 36W Full Spectrum LED Grow Light Bulb, 400W Equiv, High PPFD, E26 — Open-Box, 11% Off

4000K DAYLIGHT FULL SPECTRUM: Imitates the solar spectrum with a customized full life cycle supplementary light program, covering the entire visible spectrum of 400nm-780nm; Color rendering index Ra is close to 100, infinitely close to natural light, suitable for every cycle of plant growth, effectively promotes plant growth, and improves crop yield and quality

SECONDARY OPTICAL DESIGN: PPF: 65.6 umol/s, PPFD: 265.58 μmol/s/m² @ 1ft. Through the lens for secondary scientific light distribution, improve light utilization, give plants more supplementary light, and improve light bulb lifespan to 25,000 hours

PATENTED COC TECHNOLOGY: 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 system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, makes the SANSI bulb has higher light efficiency

SAFE & RELIABLE CONSTRUCTION: The lamp body is made of special ceramic material, and the flame retardant grade reaches V0; the reinforced insulation structure design, no risk of electric shock, is safer; the whole shell material reaches the WF2 anti-corrosion grade, which is more reliable; low IR, less heat radiation, avoiding close distance exposure burns plants

QUALITY CERTIFICATIONS: ETL listed, quality and safety verified, 5-year protection plan

ENERGY EFFICIENT PERFORMANCE: 36W grow light bulb provides 400 watt equivalent output while consuming significantly less energy, making it an efficient solution for indoor plant cultivation and reducing electricity costs

VERSATILE APPLICATION: Suitable for seeding and growing stages, this full spectrum LED plant light bulb supports various indoor plants throughout their complete growth cycles from germination to harvest

This 36W full spectrum grow light bulb delivers professional-grade illumination for indoor plants throughout their entire growth cycle. Featuring a 4000K daylight spectrum that covers the complete visible range from 400nm to 780nm, it closely mimics natural sunlight with a color rendering index near 100. The advanced secondary optical lens design concentrates light output to achieve an impressive PPFD of 265.58 μmol/s/m² at 1 foot distance, with a total PPF of 65.6 umol/s, ensuring efficient light delivery to your plants. Built with patented Chip on Ceramic technology, the LED chips are mounted directly onto a non-conductive ceramic heat sink, enabling superior heat dissipation and extending the bulb's operational life to 25,000 hours. The ceramic construction achieves V0 flame retardant rating and WF2 anti-corrosion grade, while the reinforced insulation structure eliminates electrical shock risks. With low infrared emission and minimal heat radiation, this energy-efficient bulb can be positioned close to plants without risk of burning. The 400-watt equivalent output makes it suitable for both seedling and mature plant growth stages. ETL listed for safety and quality assurance, backed by a 5-year protection plan.
