• Possible to emit even brighter and better-defined linear ray than any other similar product because each of the Light Sticks uses its built-in “Beam LED” to emit a single ray only, unlike Narika’s “Ray Box L-2 (D20-1507-W0)” of which the light source is split into three rays.

【To teachers】

• Students’ safety is secured because LED that is much less harmful for eyes than laser is used for the light source.
• Dark environment is no longer needed to observe reflection, refraction, convergence and divergence of light.
• Easy to demonstrate by mounting the Light Stick(s) on metal surface like a whiteboard owing to the built-in magnet on the back.
  – Portable because it is powered by dry cell battery.
  – Easy to manage students’ activities because experiments can be carried in a classroom with normal level of illumination (with lights on).

【To students】

• Reflection from and refraction by an object with a certain thickness will be clear and well-defined because of the 17mm thick beam in a vertical direction compared with laser beam (typical point light source) and conventional LED light source without such thickness.

• Light source: High brightness “Beam” LEDs (set of white, red, green), Cylindrical lens
• Power source: Size AA battery x 2 for each light box (sold separately)
• Size of each light box: 110 x 112 x 52mm
• Others: Built-in magnet on back surface of each light box
