Cirrus LED Grow Lights’ 1K is a high-power horticultural fixture built around 10 driverless flip‑chip COB emitters and designed to draw a true 1000 W from the wall. Retail listings document versions for both 120 V and 220–260 V mains, and a stated spectral output spanning roughly 380–840 nm. The 1K uses large heat‑exchange surfaces to manage thermal load, and is housed in a compact enclosure measuring about 23.62 x 17.32 x 5.70 inches (roughly 60 x 44 x 14.5 cm). Marketed as an alternative to 1000 W HPS systems, it targets flowering applications that benefit from strong red/near‑IR content while retaining shorter‑wavelength output. This model appeared on hydroponic retail sites as a closeout item, indicating end‑of‑line status for many shops.
