SANSI 36W Grow Light for Indoor Plants — Full-Spectrum 4000K, High-CRI COC Ceramic Heat Sink

SANSI 36W Grow Light is a full-spectrum indoor plant lamp engineered to mimic sunlight and support every stage of plant growth with efficient, long-lasting illumination.

Designed for hobbyists and small-scale growers, this 36-watt fixture delivers a balanced 4000K daylight spectrum spanning 400–780 nm, high color fidelity, and focused light delivery through a secondary optical lens system. The lamp uses SANSI's patented COC (Chip on Ceramic) technology for improved thermal management and longer life, plus safety-rated materials and an ETL listing for verified performance.

How does the light replicate natural sunlight for plants?

The SANSI grow light reproduces a broad visible spectrum (400–780 nm) at 4000K, offering color rendering near Ra 100 so plants perceive balanced light similar to daylight. This spectrum supports foliage, flowering, and general development without relying on narrow-band LEDs.

• Full visible spectrum coverage from blue to red wavelengths
• 4000K color temperature for neutral daylight appearance
• High color rendering index close to 100 for true color rendering

What performance can I expect at typical distances?

Optical engineering yields a PPF of 65.6 μmol/s and delivers about 265 μmol/m²/s PPFD at 1 foot, so seedlings and young plants receive practical supplemental light. The secondary lens improves distribution so a single unit lights a small tent, shelving, or countertop garden more effectively than a basic bare-LED bulb.

• PPF: 65.6 μmol/s for total photon output
• PPFD: ~265 μmol/m²/s measured at 1 ft for effective supplemental lighting
• Lens-driven distribution to increase usable light on plant canopy

Why does the COC (Chip on Ceramic) design matter?

SANSI's COC construction bonds the LED chip directly to a ceramic heat sink instead of an aluminum board, cutting thermal resistance and moving heat away faster. Better heat transfer preserves light output over time and helps the fixture reach a rated service life of approximately 25,000 hours.

• Ceramic heat sink lowers operating temperature for LEDs
• Improved reliability and sustained lumen maintenance
• Longer expected life compared with conventional substrate designs

Is the lamp safe and easy to use in indoor setups?

The body uses flame-retardant ceramic with V0 rating and reinforced insulation to minimize electrical risk, and the outer shell meets WF2 anti-corrosion standards. Low infrared output reduces heat stress on plants placed close to the light, while ETL listing and a five-year protection plan back product safety and quality.

• V0 flame retardant ceramic housing for improved safety
• Low IR output reduces heat exposure to foliage
• ETL listed and covered by a 5-year protection plan

Who is this for? Growers seeking a compact, reliable supplemental light for indoor seedlings, herbs, houseplants, or small grow tents will appreciate SANSI's balance of full-spectrum output, measured photon performance, and advanced thermal design. It's suitable for hobby growers, apartment gardeners, and anyone needing a dependable, daylight-accurate lamp that minimizes heat and offers long-term operation backed by safety certifications and a five-year protection plan.
