The SANSI Puck Grow Light is a 10W two-head LED plant light that puts out roughly the light of a 150W bulb. Each head has its own on/off switch, and the full spectrum runs 400nm-780nm at 4000K daylight with a color rendering index near 100, so plants get a natural white light rather than pink or purple. SANSI's ceramic heat sink is the selling point over cheaper aluminum-backed panels: it moves heat away from the LED faster, which the brand says means higher efficiency and longer life. It suits shelf, cabinet and wall growing where a slim stick-on fixture fits, and owners say it is bright for its size and easy to mount. The weak spot is the mounting tape, which several buyers say lets go once the pucks warm up.

Owners rate it well for brightness and the natural white light, and many report new growth on shelf and cabinet plants. The most common complaint is the mounting tape failing once the lights heat up.
The SANSI Puck Grow Light is a two-head LED plant light with a full spectrum covering 400nm-780nm, designed to imitate sunlight for every stage of plant growth. It gives 4000K daylight with a color rendering index (Ra) close to 100.
It uses SANSI's patented Chip on Ceramic technology. The LED chips are soldered directly onto a non-conductive ceramic heat sink instead of a traditional MCPCB aluminum substrate. This lowers thermal resistance for faster heat conduction.
The light is lightweight and has a stickable design. It can be mounted on plant shelves, cabinets, walls and in greenhouses, and in other home or office spaces. Each of the two heads has its own on/off switch. Double-sided tape and zip ties are included for installation.
