This economical ray box set delivers white light rays but runs much cooler than conventional incandescent lamp models. Five ultrabright LEDs provide parallel, narrow beams for investigating the properties of the five acrylic optical elements included in the kit. A switch on the rear of the unit selects one, three, or five rays, and the unit is powered by a low-voltage wall-mount power supply.
Includes operation manual.
