Cz Garden Supply 8.3" x 11.75" LARGE 3X Fresnel Lens FULL PAGE Magnifier - Solar Oven/DIY Projection TV PLANS (1 pack PREMIUM GRADE Large Lens)

Used these fresnel lenses to make my own "better beamer" flash extender. They want 100$ for one of those extenders and I made one for under 16$, and I have 4 lenses left over for later.

Premium Fresnel Lens 8 Pack Set. Large Full Page 8.3" x 11.75" Sheets with Credit Card Size, Bookmark Magnifier was all that was promised. Each one of the sizes was useful for different purposes. Even the little credit card size version to put in your wallet made reading small print easy and it even worked to light newspaper and kindling on fire in less than 60 seconds.

I bought the 8.3" x 11.75" Large 3X Fresnel Lens Full Page Magnifier, one for myself, one for my sister, primarily for reading books, prescription bottles, and ingredient panels on products in stores because I have some visual difficulties arising from Lyme Tick Eye Disease. I had NO idea there were so many other great uses for a Fresnel lens which appeal to survivalist/preppers like my sister and me! You can start a fire with it, much like you would using a hand-held magnifying glass, only faster and better! It is extremely useful for reading paper maps on driving trips. It is durable, flexible, and easy to store. I can also use it in my organic garden, to inspect my seedlings, and check my vine fruits for any destructive insects. I plan to buy more this spring for my 3 school-age grandchildren. They can use it to explore nature (insects, leaves, plants, flowers), for their viewing their stamp collections, and for examining fossils or seashells they find on the beach. Makes a great gift for recipients of ANY age! RECOMMENDED!

Works great. Exactly as it should. Affordable, durable, very light, about 12 inches long, easily magnified the solar light and concentrated it to a laser which cooked anything to over 1200 c.

good product
