Aluminum Housing, 220V Input, 1 LED Chip, COB Packaging Process Luminous Flux 1000-3000lm, Luminous Efficiency 100lm/W, Power 0.65W, Color Rendering Index 3000k Socket Type: Rotary, Size: 65mm, Beam Angle: 15-60 degrees, Lifespan: 80,000 hours, Weight: 600g, Power: 10W/20W/30W COB focusing spotlight, stepless iris, stepless adjustment. Rotating the lamp holder adjusts the beam angle for focusing. The lamp holder has a scale; different scales represent different aperture sizes, making adjustment easy and lighting more convenient. High-brightness chip, fifth-generation COB chip, brighter than traditional LED chips, efficient heat dissipation. A heat dissipation hole on the back effectively dissipates heat and protects the lamp. PMMA offers high light transmittance, soft light without glare, and effectively transmits light. Note: Manual measurement; slight size variations may occur, but the impact is minimal.
