Brass material: The hot and cold water mixer is made of brass with antiscratch and anticorrosion properties. If slightly dirty, wipe with a soft damp cloth, then dry. Easy and quick installation: Includes a 60 cm faucet hose, size G1/2, single hole installation, hole diameter 3.2 to 4 cm. Fits most hot and cold water systems. 1 hole single handle faucet: Waterfall basin mixer tap with waterfall spouts. Water flows into the waterfall through the outlet channel and forms a curved shape, providing a comfortable and quiet flow that reduces splashing and helps keep the sink dry. Hydro LED: No batteries or plugs required. As long as the bathroom faucet is on, the water pressure powers the LED light to illuminate. Key benefits and practicality: Durable brass construction for long life and reliable performance; simple one hole installation for quick setup; waterfall flow for a calm, splash experience; LED illumination powered purely by water pressure for visual appeal without extra wiring. Compatible and suitable applications: Fits most hot and cold water systems with a G1/2 hose and single hole mounting; designed for standard bathroom basins. Use scenarios: 1) Home master bathroom or guest bathroom to add a quiet, decorative waterfall flow with subtle LED lighting. 2) Powder rooms or small bathrooms where a singlehandle faucet saves space and provides easy control. 3) Hotels, spas, or public restrooms that benefit from durable brass construction, splash reduction benefits, and a lowmaintenance LED feature powered by water pressure.
