Very pleased with these little glow sticks to release the liquid so that the fluorescent lights stick, perform a pressure on each end of the stick, as if one wanted tweak a few things.
Once you feel the stick this "break" is done.
For me the time was very powerful: Baton cracked to 19h00 it light up again after fine 24.
And low light lasts for 2-3 days (enough to light and go to the toilet for example)
