Lens was perfect for my 3-inch lighting head. These are not easy to find anywhere unless you buy a whole new lighting head, but as usual, I found the hard-to-find item on Amazon, the exact reason why I have Prime. I had it the next day, even on a Holiday, and was thrilled that it fit with ease!

I got several of these eisco lenses, and they are packed nicely, and are perfect for kids or an educational setting. They are perfectly smooth and clear, they are washable (no coatings), and reasonable durable (no scratches yet). These are not in any way intended for use by someone doing serious optics.

Lens was chipped when I received it ! Not worth the time to return it. Other than that it was good for my machine light !
