Wireless Light Source - EP-3560


An advanced light source for use with the Optics System (EP-3558)


A key component of the Essential Physics Light & 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.

The Wireless Light Source is included in the Essential Physics Light, Color, and Optics Kit.  

Typical Applications

  • Studying image formation using lenses
  • Investigating color mixing
  • Exploring how color is produced digitally
  • Modeling how the human eye uses cone cells to perceives color
  • Demonstrating fiber optic communication

Special Features

  • Long lasting, rechargeable battery
  • Four controllable outer LEDs and a controllable inner RGB LED
  • Control the intensity of the LEDs wirelessly using PASCO software.
  • Wireless data collection to computers, Chromebooks™, or tablets.

Bluetooth Low Energy Wireless Connectivity

Required Software:

PASCO products that use Bluetooth® Low Energy connectivity (wireless sensors, Smart Carts, and the AirLink) require the latest versions of our software.

PASCO Capstone is available for Mac and Windows. SPARKvue is available for Mac, Windows, iOS, Android and Chromebooks.

Additionally, the Wireless Motion Sensor and Wireless Smart Carts can be connected via Bluetooth and used with our MatchGraph app.

Compatibility/System Requirements

Any current model Chromebook, Mac, iPad, iPhone, Android tablet or phone will support direct connection to PASCO Bluetooth Low Energy devices. Also, any Windows 10 device with Creators Edition 1703 or later will support direct connection.

Chromebook users MUST have the latest firmware updates for ALL wireless sensors in order to use them without the USB Bluetooth Adapter. Full information.

All other Windows computers/tablets, older Macs, and Chromebooks without updated sensor firmware currently require the PS‑3500 USB Bluetooth Adapter to connect to PASCO’s Bluetooth Low Energy devices.

Full compatibility details are available, including compatibility information for older computing devices.
