Brass construction with a dieformed threedimensional concave and convex texture; clear and solid texture; rust finish. Aluminum radiator with an air convection design and an oxidized finish; largearea heat dissipation ensures stable operation; quickly reduces heat and extends the life of the light source. color rendering: CRI Ra>90; a higher color rendering index restores the true colors of natural objects more accurately. Three color temperatures: 3000K warm white, 4000K neutral white, 6000K cool white; the color temperature is cycled with each power on/off; cycle is 6000K > 3000K > 4000K. Use scenarios: Home living spaces for comfortable lighting with accurate color rendering. Photography, video, and product shooting where CRI improves color fidelity. Workshops, studios, or display areas that require flexible lighting and longlasting performance.
