Review on 🔦 Cyalume ChemLight Tactical Glow Sticks by Evan Larson

They are great and work exactly as advertised. Keep in mind that none of them are as bright as you see them on TV and/or movies. They keep adding more and more light for filming. But they are bright and can easily provide 12 hours or more of light for a tent, caravan or child's room. Also great for emergencies, so keep a pair in your car's glove box or on your console. It also seems to us that they have exceeded their nominal dates by a couple of years; At this point, the light lasts just under 12 hours and goes out faster.
