This flat convex is applicable to LED spotlights, car lights, focusing flashlights, projection lights, explosion-proof lights, down lights, and other lighting products. Suitable for reading small text in newspapers, books, menus, or labels, these lenses serve as versatile tools for science experiments, DIY telescope projects, or office tasks.

Advantage:

Convex lenses are made of borosilicate glass, which is more resistant to high temperatures, has higher strength, and higher light transmittance than other materials, ensuring scratch resistance and long-term use. The beam spot is uniform, with no black holes, shadows, or dark areas. Features ground edges for safety and polished surfaces for uniform light transmission.

Instruction:

Place the lens directly over small text or objects to magnify details. With an adjustable beam angle, the actual focusing angle is determined by adjusting the distance between the lens and the LED.

NOTE:

Clean with a soft cloth to maintain transparency.
