SANSI A21 15W LED Full Spectrum Grow Light Bulbs, 2-Pack

A Simple Breakdown

Full Spectrum Sunlight Therapy

[Full Spectrum Sunlight Therapy] imitates the solar spectrum, customizing a more ideal full life cycle full spectrum supplementary light program that covers the entire visible spectrum from 400nm to 780nm. With a color rendering index (Ra) close to 100, it is almost identical to natural light, making it perfect for every stage of plant growth. This light effectively promotes plant growth, improving both yield and quality.

High PPFD Grow Light

[High PPFD Grow Light] features a PPFD of 152.83 μmol/s/㎡ at 1ft. Through a frosted lens, SANSI's grow light provides 4000K soft, even light, enhancing light utilization and giving plants more supplementary light.

Patented COC Technology

SANSI's [Patented COC Technology] uses Chip on Ceramic (COC), which replaces the traditional aluminum substrate with a non-conductive ceramic heat sink. By directly soldering the LED chip to the ceramic heat sink, the thermal resistance between the LED PN junction and the heat sink surface is significantly reduced. This results in faster heat conduction and higher product reliability, leading to higher light efficiency.

Safe & Reliable

The lamp body is made of special ceramic material and has a flame-retardant grade of V0. The reinforced insulation structure design ensures no risk of electric shock, making it safer. The whole shell material reaches the WF2 anti-corrosion grade, making it more reliable. Furthermore, it has low infrared radiation, reducing heat radiation at close distances and avoiding burns to plants.

Guarantees

SANSI's products are ETL listed and CE certified, ensuring quality and safety. The bulbs have a 25,000-hour lifespan and come with a 5-year warranty.
