Sunraise’s QB2000 is a 200 W dimmable LED quantum‑board style fixture using four bars on passive aluminum heatsinks. Retail listings specify a 22.6 x 22.6 in form factor and plant coverage up to 3.5 x 3.5 ft for vegetative growth and 3 x 3 ft for flowering. The board is populated with about 648 SMD3030 LEDs and delivers a full spectrum built from 3000K/6000K white with added 660 nm deep red and 740 nm far‑red IR to support bloom. The driver includes on‑board dimming, and the fanless design keeps operation quiet while managing heat effectively. Input voltage is listed as AC85–277 V. It is commonly marketed as comparable to a 400 W HPS/MH in small tents, making it a budget‑friendly option for 3 x 3 installations.
