A key component of the Essential Physics Light and Optics module, this rechargeable light source has four colored LEDs at the edges and a powerful RGB LED in the center. It also connects directly to your devices and streams data via Bluetooth 4.
The light source makes a perfect illuminated “object” for optics experiments, and the fixed spacing of the colored LEDs makes it easy to observe and measure image properties such as magnification, inversion, and brightness.
The rechargeable light source lasts all day and you never need batteries! The four colored LEDs (R/Y/G/B) on a 10 mm spacing make it easy to make precise magnification measurements and see image inversion.
The bright central LED is actually 3-in-1 and includes separately controlled red, green and blue (RGB) sources. This allows you to teach the technology of color with powerful lessons that apply to many technologies such as LCD screens, digital cameras, video, and fiber optic communications.
