  High power super bright LED light.   *Long service life LED.   *Great for making light sources for video camera, fish tank, decoration light.   *Type: COB LED.   *Power: 3W/5W/7W/10W/12W   *Voltage:    3W: DC 9-12V               5W:DC 15V                7W:DC 21-24V          10W:DC30-32V               12W:DC36-40V  *Current: 300mA.   *Luminous Flux: 3W:300-330LM      5W:500-550LM          7W:700-770LM            10W:1000-1050LM         12W:1200-1260LM  *Color Temperature:  Warm white  3000-3200K                                            White:4000-4500k                                        Cool white  6000-6500K  *Outline Dimension:  Φ 28 mm.    Luminous Dimension: Φ 20mm  *Lighting Angle: 120 degrees.     COB LED is less thermal resistance:  *Among different LED components such as high power LED, SMD, dip etc, COB LED is best in less thermal resistance and cooling.     COB LED is better lighting effect:  *COB LED: No dizzy, no uncomfortable glare, no zebra strips. When it light up, it looks smooth and like a lighting panel.   *SMD, HP, 5mm LED: heavy dizzy, uncomfortable glare, heavy zebra strips. When it light up, it looks dots. A Milky or diffused cover can improve, but at the same time it cause light loss
