So those battery comments and the issues of humidity or even cold weather or very hot is where your basic Duracell Batteries fall vintage light way short and thus the electromagnetic induction makes more sense. Police, first responders, military, astronauts, security professionals all work in adverse environments. And if we are going to build a better mousetrap in a safety light, then we must consider these issues. And if you have ever been stuck at night with a blow out in the weather or dark of night you too have experienced this problem. One recent comment from a member of a think tank indicated that there were not only issues in adverse weather with the battery life and dimming, but also with diffraction of the light taking place in mist, high humidity, fog or rain.

There are slow issues with Dizziness, because that is an issue with human vision, light and motion, so a proper safety light engineer needs to look into that too, as well as the diffraction of the light in the fog at night.

Those who comment on battery life issues know all too well how serious these issues are. I encourage those who design flashlights, safety lights, mounting brackets, batteries and alternative energy sources for such things to work hard and push forward to making a unit that is truly safe for the human race a reality we can all count on.

In other words if we cannot trust the batteries; then we cannot trust the light and with that said, we need engineers and designers to be cognizant of the challenges that those face in the real world.

One very serious issue with safety lighting is that they run off batteries and in adverse conditions these batteries do not run at their peak optimum.

. More effort needs to go into the designing of lighting to insure that those who are in need have the light they need. Please be thinking here. Although LED Light will be better for this, it still has the basic issues of physics to deal with. This causes lights to dim and that could spell disaster for the user in a critical situation.
