    Good

    posted by Josh101 on 03/12/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    Used these for a custom 1W led light, i needed a wide beam with a small profile. the lens works fine and is made of acrylic, this was good for me because i was able to shave the sides down to make it fit. hard to do with glass. all were in good condition wi...
    Cons:
    small lens's with wide focus, not suitable for a tight focus but at this size probably not a problem.

    affordable lens for small flashlight

    posted by shing97 on 03/05/2011 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    20 lens for less than 3 dollars, you can't find in some where else. It is small, so it can fit some of my small flashlight. It really helps concentrate the light beam. It is plastic, so you can easily glue it to any surface.
    Cons:
    It cannot fit to bigger flashlights. To them, it may even weaken the lightness, and cause a dark circle inside of the beam.

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    High quality plastic lenses for your all needs. I use it in optoelectronic projects to improve focus and range of optical sensors. May also be used for other purposes. Somewhat pricy. One side is convex the other side is flat. Strongly recommended for all D...
    Cons:
    the price is high for a bunch of plastic but it may be worth the price depending on application

    Pros:
    Nice product. These plastic lenses are of equal quality between each other..All arrived in good condition, not scratched etc. Works great.

    Well here is a little plastic lens that focuses a 120 degree high bright LED into a nice tight spot with the die from the led projected as an image in the hot spot. They come in a pack of 20, all of mine are very consistent
