Short Description:

High quality flashlight manufacturers have a little trick up their sleeve that you may not even be aware of. Many of them use glass lenses made of special compounds or are specially coated to improve light transmission from their flashlights. The benefits of these glass lenses is threefold. First, more light can be transmitted through glass than most plastics that are used for inexpensive flashlight lenses. This means more light coming out of the end of your flashlight. Second, glass lenses are much more scratch resistant than plastic, and that spiderweb of scratches that forms on the plastic lenses will scatter the light instead of letting it go where you need it. Third, high intensity lithium powered lights can melt plastic lenses if they come on accidentally in their belt sheath or if left on for extended periods of time. Glass has much greater high temperature tolerance and won't melt under these circumstances.

Until recently you would have to buy a quite expensive flashlight to get the benefits of having a glass lens, but now they are available separately. produces high quality replacement glass lenses for several manufacturer's flashlights. Now you can buy a less expensive light, add a lens and gain all the benefits of having a glass lens.

Currently uses 3 types of glass, each with its own benefits.

Borofloat is a form of borosilicate glass similar to Pyrex.. Borofloat is extremely temperature resistant and won't shatter if your hot flashlight is dropped into a cold stream.

B270 Superwite is the most scratch resistant glass replacement lenses that they have with better transmission than the Borofloat, almost matching that of the UCL lenses.

UCL (Ultra Clear Lens) transmitts over 99% of all visible light. This means that you will be getting the most light possible out of your flashlight. These lenses are also coated to be anti-reflective, water repellent, and anti-glare. These coatings allow the lens to remain a optically clear as possible under a wide variety of conditions.

Reviewer's Impressions:

I'm really going to let the pictures above do the talking for me. You can literally see the difference between the stock lenses and the replacement lenses. Add in the scratch resistance and temperature tolerance and you've got a real set of winners.

The lenses are perfectly clean out of the package, have no sharp edges, and fit well in the lights. At the time of this review, lenses were available for the Tigerlight, Brinkmann Legend LX (includes O-ring for better fit), Pelican M6, Minimag, Brinkmann 2-AA, Mag C and D cell lights, and the Streamlight SL series.

Cost? At the time of this review, $3.75 to $7.00 depending on the lens. Shipping is free. International delivery available for a fee.

All in all, if you want a very simple, inexpensive, and effective upgrade to your flashlight, get one of these lenses. In my opinion it's well worth the cost.
