Lumica 6 Military Grade Safety Light Stick - WHITE x 10 by Lumica Light

Good size, easy to activate that lasts ages once activated and produces a good amount of light. I use these when scuba diving at night or in poor visibility so that I can see my buddy and they can see me without blinding each other by shining a torch. The carabiner style clip allows you to just clip it anywhere you want to. Good product at a good price.

I packed these in a mountaineering first aid and emergency pack. They were bright as hell, good quality and lightweight.

Nice white and reasonably bright glow. No duds in the pack, light was consistent between the glow sticks. Was purchased for light painting but with the exposure times we were using these were too faint, not really a criticism of the glow stick, but if you were planning to use for light painting you would need low ambient light and very long exposure times.

Great for blackout

We purchased for our fire evacuation box and fire marshal jackets. We tested one just to check the length of illumination. They reach full brightness rather quickly and hold on to it for a good amount of time. But like all glow sticks they will dim over time. But as an immediate PPE for low lighting, they are sufficient for our emergency use.

In the Royal Navy Submarine Service these were in escape packs and were quickly renamed Cooo Sticks reading some of the reviews I think peoples expectations might be a little too high for them. These are ideal when sea kayaking at night as they aren't blindingly bright but glow white. You can read by them however you need to put the light stick on the map/chart. For those that want something in between a torch and light stick look at Glo-Toobs they are small battery operated and have a range of operating modes, they come in different colours and there depth is down to something like 60m (though check first). A tip for Light Sticks if you want to increase their visibility to attract attention, tie a length of cord in the eyelet and spin the stick around like a propeller what that does is increase the area in which it can be seen.

Lumica light sticks are great, I've used them many times whilst camping. Just to be clear, these are the 8 hour light sticks. Lumica also make 12 hour light sticks, which is all I've bought previously.

Long lasting and surprisingly bright, what more could you ask for?

Ligeros, facilisimos de usar y con una luz muy intensa que se queda encendida durante mas de seis horas. Caben en cualquier bolso o por supuesto mochila y en casa son utiles en caso falle luz y linternas. Volvere a comprarlas.
