Light Blox - LED color mixing educational kit

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.

The lasers in the magnetic cases are SO helpful for many different Lab applications in Physics and Chemistry!

These are great tools and the students love them. We have a couple dozen of the kits from the previous company and their #1 issue was many switches would break or wear out about halfway through the second school year of use. About 30% are dead now as they are still failing. An EE friend of mine, who took some of them apart, said the switches were cheap and not made for high cycle use. I had hoped my complaints and suggestions would result in better switches in the new units. We just received new units to replace some of the old ones and the switches appear to be the same. I hope I am wrong. I'll find out next year.

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.

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.

My 6th grade students completed the Khan Academy Pixar in a Box unit on Color Science with lessons on RGB pixels, HSL and how we perceive light. The Light Bloxs provided some great hands-on learning to see the application of color mixing and light bending through the use of lenses.

Our class was doing reflection and refraction labs and these lights have a cap that makes a "slit" that worked perfectly. Way better than flashlights and tape, which are a nightmare. I am ordering more!

This is a great little light mixing/bending demo. The only reason I couldnt get the product 5 stars is the magnets dont stick well to the whiteboard. Stronger magnets on future iterations would be better.

They came quickly and work very well!

These are perfect for demonstrating color addition and a safe alternative to a laser for other uses.

Love them. I like that I am able to project a line and not just a dot.

Works well with large acrylic lenses

Works well with large 7 to 8 cm tall lenses.

I love these light sticks. They are easy to use, easy to see, and inexpensive.

It was very effective to show the additive process with the primary colors of light.

I thought they worked best with the collimator slit cover off. The 'white' combination is a little tricky to get; it isn't glaringly white. Other color combinations were great. Good strong well collimated lights.

In the past we have used LED projectors for part of our optics lab. This required low to no light background. We also use an optics bench for refraction and reflection experiments again in low to no light and using fairly complecated procedures. The good news is that we a integrating in the light sticks as they can replace almost all of the other equipment and will introduce FUN not Frustration in this lab experience.
