Review on 🔦 Cyalume 9-27631 VisPad: High-Visibility ID and Marking Emitter for Optimal Safety by Noah Lewis

First of all I would like to say that they should not be considered a substitute for traditional chemical rod burners in most situations. The luminous flux is not at all like a good chemical lantern. However, for marking and identification purposes they work very well and are much more convenient to use than a chemical flashlight. The adhesive backing sticks to most clothing fairly well, but slips off during aggressive movements like running and doesn't handle moisture well. There's enough light output to see up to 75-100 meters with the naked eye, but after that it gets pretty dim, at least to my eyes. The "burn time" was exceptional, staying at full brightness for around 8 hours and continuing to glow for at least another 10 hours, slowly dimming. were treated. They can be a great organizational tool to use with a color coding system to identify injury types and treatments. It is also useful to be able to write on it, for example blood group, treatment time/injury, etc. They're also useful for tagging teammates for late-night simulations. It would be great to see their IR version. Sometime. I would certainly recommend them for specific purposes, but not as a true replacement for the traditional chemical flashlight.
