## Description

4000K DAYLIGHT: Imitate the solar spectrum, customize a more ideal full life cycle full spectrum 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: 16.8umol/s, PPFD:97.91μmol/s/m² @1FT: . Through the lens for secondary scientific light distribution, improve light utilization, give plants more supplementary light, and improve the 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 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, makes the SANSI bulb has higher light efficiency SAFE & RELIABLE: 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 GUARANTEES: ETL listed, quality and safety verified, 5-year protection plan

Review: Not good - Bought this bulb few days before, now its gone, not working

## Questions & Answers

**Q: How do I determine light needs, height, and duration for my plants?**
A: Check your plant's Daily Light Integral (DLI) and use our PPFD values at different heights to calculate optimal lighting duration.

**Q: How does this light compare to red and blue spectrum lights?**
A: Our 4000K full-spectrum light mimics natural sunlight, suitable for various plants without causing light pollution. Ceramic construction ensures durability and safety.

**Q: How energy-efficient is this grow light? Will it significantly increase my electric bill?**
A: Our LED grow light consumes 10W, costing approximately $0.43 per month (12 hours/day) at $0.12/kWh. LEDs like ours are highly efficient, providing cost-effective lighting solutions for plant growth.

**Q: I prefer growing tropical plants. Is this light suitable for that?**
A: Yes! Our full-spectrum light mimics natural sunlight, essential for tropical plants. With a high PPFD of 265.58 μmol/s/㎡@1ft, it promotes fast photosynthesis and robust growth, evenly illuminating plants for compact, symmetrical growth.

**Q: What's the best light for indoor plant growth?**
A: Plants need specific light at different stages -more blue for growth, more red for flowering. Our Full Spectrum Lights meet these needs and provide optimal conditions. Adjust duration and maintain optimum height above plants for even growth.
