Review: Give lighthouse visitors as Wow experience. - Excellent for demonstrating how Fresnel optics work in scaled lighthouse demos. When paired with a small, bright LED, the lens produces a convincing, highly directional beam that illustrates the principle of concentrating light for visibility at a distance. For the best effect, use a pointlike light source, keep the lens flat, and shield stray light so the beam appears crisp.
Review: Nice. Better than credit card sized ones! - I experimented with both this bigger one and the smaller credit card size versions. The little ones did make smoke and embers, and I probably would have gotten a fire going with the little ones with a little more effort. The big one, oh yeah. I was drawing scorch marks across cardboard like it was a sharpie. Definately could have started a fire with this, if that was the intention.

## Features

- Great for Physics Classroom Education, Solar Heating Experiment, DIY Solar Project, Magnifying, Scientific Research
- Optical education: The special structure of the Fresnel lens can adjust the parallel light or the focused light, so that the light is effectively directed to a specific narrow area to achieve the focusing effect of light. The children were curious about it.This is not only a base, but also a knowledge point that children need to learn.

### ⭐⭐⭐⭐ recommend, but be advised the concentrated solar laser is in excess of 1200C*
*by M***S on July 28, 2025*

it worked great to concentrate the sunlight into a dangerosly hot laser. i was able to etch my name into cocrete and get some glass to a molten state. The round design left me wishing it would have been rectangular so that it would have been easier to construct kind of a stand for it.
