Finally, hands-on color-mixing with light
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.
With the caps off, these classroom LEDs are perfect for creating the secondary colors of light (yellow, magenta and cyan) with additive color mixing. Or, mix all 3 for white light.
Perfect classroom tool for Reflection and Refraction
With the caps on, LightBlox double as a ray box! They project an 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 - no expensive equipment needed. Make the science of light and optics fun and accessible for students in grades 3-12!
Free lessons and activities included for mastering 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 dozens of labs, experiments, lessons and activities for mixing primary colors of light, reflection, refraction and more with LightBlox. Available for download in your order confirmation.
The Easy Way to Learn About Light
Reflection
Explore how light bounces in reflection with mirrors and other shiny surfaces.
Refraction
Learn why lenses bend light to form images in eyes, microscopes and telescopes.
Color Mixing
Blend your own color combinations to make new colors of light!

Came on time as stated in the order. Wish the plastic boxes were colored like the previous boxes that we replaced them with. The new ones just have a colored dot on one side.
They are one of the best colored light sources I have owned! The removable slits produce a narrow beam that are useful for reflection and refraction experiments.
I use them for my Color Theory workshops and Physics classes for homeschoolers. I also bring them along when I travel to conferences with my book Lightlab.
I have several sets of the light blox for the classroom. We make the room dark and use them to explore color mixing and shadows. We also use them to analyze how items reflect light like M&Ms. It is part of the section on color mixing. Students are used to red blue and yellow so doing this really makes them think how they see color. We tie it in with how the eye works. It is one of their favorite labs (high school, college and STEM days.
I darken the classroom, lay white butcher paper on the lab tables, and put up cardboard “screens.” With the lights out, I walk around handing student teams one tool at a time: Light blox without their caps, one color at a time, then the caps, then lenses, then the half circle empty and with water, and finally mirrors. The students enthusiastically explore many light phenomena. Once that free exploration has happened, then I guide specific explorations of color, refraction and reflection. The students love the tools. And the blox and accessories work to teach the science.
