Roleadro COB 400W is a compact, full‑spectrum COB grow light that uses two 200 W Epileds COB modules with active cooling. Independent listings report an actual wall draw around 200–210 W, making it a budget option for small indoor gardens. Typical coverage is about 1.2 m², with a reflector‑cup design to focus light and improve canopy penetration. The housing measures approximately 29 x 17.5 x 8.3 cm and weighs about 2.5 kg. The spectrum spans roughly 380–780 nm and lifetime is commonly listed near 50,000 hours. Many retailer pages note daisy‑chain or power‑link capability for simple expansion.
