RGB LED Flashlights

Demonstrate additive color mixing with three colored light sources

The RGB LED Flashlight Set gives teachers a simple, visual way to demonstrate additive color mixing at the front of the class. Aim the red, green, and blue beams onto a white surface in different combinations, and students see the results directly: red and green produce yellow, red and blue produce magenta, green and blue produce cyan, and all three together produce white. No software, no projector setup — just three flashlights and a wall.

Each aluminum alloy flashlight runs on one AA battery (included) and has a zoomable head, so the beam can be narrowed to a tight spot for clean overlaps or widened to fill more of the projection surface. Operation is single-mode on/off only, so there's no fumbling through strobe settings mid-demo. At 200 lumens each, the beams show color mixing clearly, even in a partially lit room.

Why Teachers Love It

• No Setup Required – Point and aim at any white surface. There's no calibration, no alignment, and no equipment to assemble before class.

• Zoomable Beam for Precise Overlaps – The adjustable head lets you control the beam width, keeping overlapping colors clean and easy for students to read from their seats.

• Immediate Correction of the Paint Mixing Misconception – Students who expect red and green to produce brown are immediately corrected when yellow appears on the wall. The demo settles the additive vs. subtractive color confusion faster than any verbal explanation.
