I bought these Glow Sticks for night diving & they work perfectly. They have a little clip at the top that will fix straight onto a 'D ring', etc so no messing around with tying them onto things. Simply unwrap, clip on, crack, shake & you're away. Strong, consistant light for hours & they're totally waterproof!
Great price for some great light stick. These are not your normal camping glow stick, they have a NATO logo on then and as the title suggests they are military grade light stick. Very bright, not sure if they last the whoel 12 hours though.
We bought these glow sticks as there the same ones they issue my niece with at army training. they do last for a good 9 hrs which is normally sufficient for there night exercises they hold. Well worth the price and great for the odd home emergency when the power goes off.
