That is just WRONG-HEADED! Well, the folks at Glycine are clearly RIGHT-HEADED! The lume on the dial of the MLV glows like a torch as soon as you walk into a dark area. No "pre-heating" required. This is practical, because, in all honesty, do you generally travel around with a high-powered flashlight at any given time? Police, fire and rescue workers notwithstanding, I feel the safe answer is no. We live in the real world, and it is very clear that Glycine took this into account. No-nonsense, performs exactly as advertised!
I wrap-up my review of the Airman MLV tomorrow - stay tuned!
