Whats the difference in the Photon 6.5S and the Photon 6.5L?
The 6.5S model has an LED IR illuminator, the 6.5L has a laser IR Illuminator, and the 6.5L model is $50 more than the 6.5S. The laser IR on the 6.5L throws farther than the LED IR on the 6.5S, but the laser is much more grainy than the LED IR illuminator on the 6.5S which throws a nice smooth circular beam pattern. Both on-board IR illuminators offer less than enough beam throw and distance to allow the operator to advantage of the Photon XT 6.5(S and L) impressive range capabilities. Both on-board IRs also have a fixed beam pattern, meaning there is no option to focus the beam pattern smaller or in a different direction. If you don’t plan on using any type of external IR illuminator, it is best to choose the Photon XT 6.5L. The IR laser on this model consumes less battery power and offers better range.
There is, however, an external IR illuminator option that offers incredible throw distance, a focusable beam pattern, and better battery life – the UNV 20-IR Long Range LED IR Illuminator. If you are considering the use of an external IR, then there is no need to spend the extra $50 for the 6.5L model. Go with the 6.5S, and add a UNV 20-IR.
