【Excellent Craftsmanship】The die-cast aluminum housing of this chrome ceiling downlight undergoes anti-rust treatment, resulting in a spotless and rust-free appearance. The 1mm thickness outer edge seamlessly blends into your ceiling surface. The 30° tiltable angle provides more choices for the lighting range 【Multiple Protections】The pre-wired GU10 lampholder with double insulated cables ensures safety during use. The fireproof connector meets BS & EN standards for supplementary protection and is equipped with live, neutral, and earth wire, making the recessed GU10 spotlight safer and far more efficient than halogen downlights 【Dimmable & No Flicker】The supplied 5W 450lm LED bulbs are dimmable, offering fully smooth dimming from 100% to 0%, compatible with most household LED dimmer switches. You can adjust it from a full bright glow to a dim cozy color. No flickering occurs, which can protect your eyes 【Detachable Design】Each bulb is equipped with a standard GU10 lamp holder and terminal block. As the bulb is detachable from the holder, it's more convenient for installation and future bulb replacement.
