Lumica 4 Hour Lightstick

These are tiny weeny. Was going to use to attach to a swimming costume for night swim but probably best used to find your gear on a dark night or lay down as a little marker to retrace your steps. Or as a light sabre for a mouse. Good though!

Excellent product, does what it says and is extremely bright for the size of it!

I bought a few for my daughter , The are working for more than 8 hours.

The best glow sticks/ Chem lights hands down. Cracked one open it lasted for 12 hours easily, despite only saying 4 hours. Sure it was dimmed slightly, but still amazing. You just can't beat this quality, for such a cheap price. I use the reds for night time training exercises. Blue is icy blue, real nice colour.

Four hours my foot. Bought one of each to test them out and sat them in the kitchen for four hours. Still going strong when I retired for the night, I spaced them out along my corridor to mark the guard rail... A further four hours later they were still going strong. Albeit with the blue harder to see due to its colour. Green and red I'd recommend all day long. By morning they were still glowing, but I couldn't vouch for their usefulness at that point. Found them surprisingly hard to bend (to activate) but I would posit that this would make them difficult to accidentally activate. Not having anything to compare them to, this might be normal. However, I'd not want to try it with frozen fingers, and heaven forbid with gloves. Not sure if their value holds to their cost however, as any reasonable amount of them will start costing vast sums of money - at which point larger offerings or electronics might be a better investment. For the same price as these you could get a strobe that lasts a few years.
