The VisorLight is lightweight and clips right on to the Optivisor (and most other headband magnifiers). Made in the USA by Donegan, the same company that makes the Optivisor. It runs on AA batteries that power a xenon laser beam light that is amazingly bright and easy to focus. Battery life is 5 to 6 hours. VisorLight is pictured with the Optivisor, which is sold separately.
LT-42 with a 42" long cord so the battery pack can be worn on a belt or placed in a pocket or mounted on the visor magnifier, and LT-06 with a 10" cord so that the battery pack can only be mounted on the headband of your Optivisor.
