Primary Color Light Sticks

Highly disappointing. The magnets are incredibly weak, and once the batteries are in place, the light sticks slide down the board. Also, the beams diffuse quickly, so using them for a class demonstration of color mixing is difficult. The distance between the light sources and the screen must be very short in order to see decent results.

Great product

This is a great little light mixing/bending demo. The only reason I couldn’t get the product 5 stars is the magnets don’t stick well to the whiteboard. Stronger magnets on future iterations would be better.

Primary Color Light Sticks

Dear Arbor, I was looking for a collimated light source for the Introductory Optical System 92-7700. Upon opening the Arbor packing it was quickly apparent that I had misordered, since the light sticks have no collimating lens. The intended collimating purpose aside, however, the light sticks are well made.
