SANSI LED Grow Light Bulb for Seeds & Greens – Full Spectrum 10W (150W Equivalent) | E26 Base, 4-Pack

Elevate indoor gardening with the SANSI LED Grow Light Bulb, designed for seeds and greens. Emitting a faithful daylight feel, this 4000K full-spectrum bulb covers the visible spectrum from 400nm to 780nm, delivering light that closely resembles natural daylight. While results will vary with setup and plant variety, many indoor growers notice more vibrant foliage and steady growth when using consistent, full-spectrum light.

Precise spectrum and realistic color rendering

The bulb is engineered to approximate natural light with a color rendering index near 100, helping you observe true leaf color, vein structure, and new growth. Its 10W LED yields a 150W-equivalent output, making it suitable for compact grow spaces, seed starting trays, and small herb gardens in kitchens or apartments.

• Full spectrum 400nm–780nm supports multiple growth stages
• 4000K daylight temperature for a neutral, natural-looking glow
• CRI close to 100 for accurate color perception

Efficient light distribution and long-lasting performance

Through a secondary optical design, the bulb delivers a measured PPF of 16.8 μmol/s and PPFD of 97.91 μmol/s·m² at 1 ft, helping you achieve more uniform light delivery to your plants. The patented chip-on-ceramic (COC) technology and ceramic heat sink reduce thermal resistance, supporting faster heat dissipation and higher reliability. With a rated life of up to 25,000 hours, this bulb is built to reduce replacement frequency while maintaining consistent output.

• PPF: 16.8 μmol/s and PPFD ~97.91 μmol/s·m² at 1 ft
• Chip on Ceramic (COC) technology for efficient heat management
• Ceramic heat sink enhances durability and performance

Safety, reliability, and peace of mind

Safety features include a flame-retardant shell rated to V0 and reinforced insulation, minimizing risk and allowing closer plant interaction without overheating nearby foliage. The shell also offers WF2 anti-corrosion protection and reduces infrared radiation. This is supported by third-party verification with ETL listing and CE certification, plus a 5-year after-sale service to back up the product’s longevity.

• V0 flame retardant-grade shell and reinforced insulation
• Low IR output and reduced heat radiation
• ETL listed, CE certified, with 5-year service

What you get and how to use

Each pack includes a 4-pack of 10W bulbs with an E26 base, designed to deliver practical, reliable performance for seeds, greens, and small indoor setups.
