Features:

  • Frosted optical design: PPF: 27.2 umol/s, PPFD: 130.06 μmol/s/㎡ @ 1ft. Through the frosted lens not only provides soft and even light improves light utilization, gives plants more supplementary light; but also through 120° beam angle covers more plants.
  • Imitate the solar spectrum: Customize a more ideal full life cycle full spectrum supplementary light program, covering the entire visible spectrum of 400nm-780nm; Color rendering index Ra is close to 100, infinitely close to natural light, suitable for every cycle of plant growth, effectively promotes plant growth, and improves crop yield and quality.
  • Patented ceramic technology: Chip on Ceramic, SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, and directly solder the LED chip on the ceramic heat sink, effectively reducing the system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, makes the SANSI bulb has higher light efficiency.
  • Safe and reliable: The lamp body is made of special ceramic material, and the flame retardant grade reaches V0; the reinforced insulation structure design, no risk of electric shock, is safer; the whole shell material reaches the WF2 anti-corrosion grade, which is more reliable and durable; low IR, less heat radiation, avoiding close Distance exposure burns plants.
  • Guarantees: ETL listed & CE certification, quality and safety verified, 25,000 hours lifespan, 5 years warranty.

Chip on Ceramic (COC) Technology 

SANSI's patented COC technology directly solder the LED chip on the ceramic heat sink, effectively reducing the system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability.

Nice umbrella stand
This stand is sturdy enough for my 9 ft umbrella. I only used water to fill it so it can be moved if necessary. The umbrella is taken down if it gets too windy as it would be damaged. This would not be the fault of the stand, just the nature of living near the coast.

Umbrella base
This umbrella base comes with a hole in it, in order for you to put sand in / water. You could get water in it a lot easier than you could sand. There's a tiny hole and the sand does not go very well down that hole. I've had a hard time trying to get the sand in. It is round in shape which makes it easier in the wind to tip over. But all in all for the price it was okay.
