Round LED Panel - 3W - 5V - RGB Light - LED Module
The RGB LED panel is high-quality lighting and a color light source with low power consumption. Compared to traditional light bulbs, it is up to 80% more economical with a 10 times longer lifetime. High-quality LED modules are used in general LED lighting.
They are perfect for the construction of LED lamps, halogen lamps and floodlights as well as for your own DIY projects. Modules require additional cooling through a heat sink.
The great advantage of LEDs is the lack of harmful ultraviolet (UV) radiation for human eyes and skin as well as for works of art.
Technical data
LED power: 3 W
Lifetime: 50000h
Working voltage: 5V DC
Diameter: 31 mm
This requires 5V DC so providing 9V may likely damage the module.
