Engineered with patented Chip on Ceramic technology and secondary optical lenses, it provides efficient light output (PPF 16.8μmol/s, PPFD 97.91μmol/s/m² at 1ft) to optimize plant growth across all stages. Its durable ceramic construction offers superior heat dissipation, safety, and a long 25,000-hour lifespan. ETL certified and backed by a 5-year warranty, this bulb is the professional choice for indoor gardening and seed starting.

## Description

This 10W full spectrum grow light bulb delivers 150 watt equivalent illumination designed to support plants through every growth stage. The 4000K daylight spectrum covers the complete visible range from 400nm to 780nm with a color rendering index near 100, closely mimicking natural sunlight to effectively promote plant growth and enhance crop yield and quality. Featuring secondary optical design with specialized lenses, this bulb achieves a PPF of 16.8mol/s and PPFD of 97.91mol/s/m at 1 foot distance, maximizing light utilization for optimal plant supplementation while extending operational life to 25,000 hours. The innovative Chip on Ceramic technology directly bonds LED chips to a non-conductive ceramic heat sink, eliminating traditional aluminum substrates to reduce thermal resistance and enable faster heat dissipation for improved reliability and light efficiency. Constructed from special ceramic material with V0 flame retardant rating, the bulb incorporates reinforced insulation structure and WF2 anti-corrosion grade materials for enhanced safety. Low infrared emission minimizes heat radiation to prevent plant damage from close-range exposure. ETL listed for verified quality and safety standards, this grow light bulb is suitable for indoor plant growing and seed starting applications.

## Features

- 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

## 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.
