Product Description

Explore the Primary Colors of Light with Light Blox!

Bright, beautiful, classroom safe LED's in the three primary colors of light (red, green and blue) for color mixing and more!! Introduce additive color mixing, reflection (how light bounces) and refraction (how light bends) with one fun, inexpensive set of Light Blox LED's. 

The primary colors of light - red, green and blue are not like the primary colors of pigments - when you mix all of the colors of paint, you get a mess - but when you mix the three primary colors of light, you get white light. All of the white light we live in every day is made up of many wavelengths of light, but our eyes are only able to perceive red green and blue. HERE is a lesson about additive color mixing. 

With the caps OFF, these sturdy, designed just for the classroom LED's are perfect for mixing up the secondary colors of light (yellow, magenta and cyan) as well as for mixing a pure white light. Take color mixing of the primary colors of light out of the abstract with Light Blox - a hands-on science tool for the classroom!

Reflection and Refraction

With the caps on, Light Blox double as a ray box! They project a bright and easy to see beam in each of the primary colors of light (red, green, and blue), perfect for exploring how light bounces (reflects) and bends (refracts). Students easily and intuitively uncover the law of reflection or measure the angle of refraction.

Explore, inquire and observe all the properties of light with one simple tool: Light Blox! No need for lot's of expensive pieces of science equipment to make the science of light and optics fun and accessible for students in grades three through twelve and beyond!

Lessons and Activities with the primary colors of light

Light is a visually engaging and fun topic for kids and adults, but it can be abstract and difficult to teach also - so we've created and posted dozens of labs, experiments, lessons and activities for mixing primary colors of light, reflection, refraction and more with Light Blox on our FREE Lessons Page. Whether you want to teach about the primary colors of light or reflection and refraction, you are sure to have fun with Light Blox!

  1. Poor control of light. Weak output.

    Posted by Brian Park on 8th Aug 2018

    Product is poorly designed. Most of the light spills out the sides, through the case. This is because the case is not black, and a diffused LED is used instead of a non-diffused one and a focusing lens. Those involved in science education should know better! LEDs are available (for the same cost) that have integral optics to collimate the light. What Were You Thinking?

  2. Light Blox

    I love this product. I have ordered multiple sets that are used in different centers and the kids love them also. Great product!!

  3. These provide great beams of light for multiple optics uses.

    Since it is the International Year of Light, I set up optics stations for the first day of class. Three of the stations used Light Blox: one used them with lenses, one with mirrors, and one for color mixing (with the covers off). It is easy to see how the light beams are bent by the curveryd mirrors and lenses. Students can rotate the lenses and mirrors to see how that affects the beams of light. Great tool, easy to use, and appealing to look at.

  4. Great for open-ended investigations and demonstrations!

    Loving these light blocks so far, I like how you can project a narrow or wide beam, and how well they work with some simple lenses and mirrors. The magnets on the light blocks are insufficiently strong to hold them to my whiteboard, but they work really well under the document camera with the room lights turned off. Stronger magnets would definitely be a plus, but even without them I am very happy with this product.
