SANSI 36W Full Spectrum Grow Light Bulbs for Indoor Plants – 400W Equiv, Optical Lens, ETL

Enhance Indoor Growing with a True Full-Spectrum Light

The SANSI 36W full-spectrum grow light bulb is crafted to mimic natural daylight, spanning 400 nm to 780 nm. Its high color rendering (Ra near 100) helps plants appear vibrant and true to life, supporting growth across seedling, vegetative, and harvest stages. Compact and easy to integrate into small spaces, this bulb can supplement limited natural light on overcast days or in rooms with reduced sun exposure, helping you maintain steady plant health year-round.

Key Specifications at a Glance

Thanks to a secondary optical design, this bulb concentrates light for efficient use in compact setups. It delivers a PPF of 65.6 umol/s and a PPFD of approximately 265.58 umol/s/m² at 1 ft, providing meaningful, targeted illumination without excessive heat. The design supports longer use with an anticipated lifespan around 25,000 hours, reducing replacement frequency and maintenance effort.

• 4000K daylight spectrum closely mirrors natural light for versatile growth.
• CRI Ra near 100 for accurate color rendering of plants.
• PPF 65.6 umol/s and PPFD ~265.58 umol/s/m² at 1 ft for meaningful intensity.
• Long life of ~25,000 hours with efficient heat management.

Durability, Safety, and Reliability

The bulb uses Chip on Ceramic (COC) technology with a ceramic heat sink, improving heat conduction and reliability. The outer shell is ceramic with flame-retardant properties (V0) and reinforced insulation, plus corrosion-resistant materials to endure regular use. It is ETL-listed and backed by a five-year protection plan, offering peace of mind for home or studio setups.

• Ceramic COC technology enhances heat dissipation and longevity.
• Flame-retardant ceramic shell and reinforced insulation boost safety.
• Low infrared output minimizes heat exposure to leaves and nearby surfaces.
• ETL-listed with a 5-year protection plan for dependable performance.

What This Means in Real Life

Whether you’re starting seeds on a countertop tray, nurturing young clones, or extending grow hours in a dim corner, this light provides usable, scalable supplementation. It pairs well with compact grow setups, apartment gardens, or setups that need consistent light without occupying a lot of space. You’ll notice the spectrum’s warmth in how plants respond, and you can plan light cycles with confidence, knowing you’re delivering a balanced, daylight-inspired spectrum.
