30 Ultra Bright Glow Sticks in Bulk – Multi Use Glowsticks for Parties, Camping, Emergency Light and Survival Kit with 12 Hours Duration by Glow Mind

I ordered two packs. Both packs came with 5 of each color.

Additionally, I cracked one of each (to figure out what color was what) and it’s been at least five hours and all of them are still glowing.

They did lose their initial brightness intensity in the first hour, but the dimming has slowed considerably. The pink *definitely* looks like it will have the shortest life and has dimmed noticeably more than the others.

This may be a consequence of the different fluorophore in them, and it may be that pink just is the weakest chemical.

In terms of actual brightness and being able to see things, I would say that at this point – five hours in – green is the most illuminating followed by blue. Yellow is a close third. Orange and pink are about tied, and red is the worst. Though this is more a consequence of how the human eye works.

Finally, if you’re wondering what the colors are:

Clear fluid = blue.
Green fluid = green.
Orange fluid = yellow.

For the other colors, it’s harder to tell because they all appear to have a pinkish liquid in them. Shake the stick up and put it on its flat end.

If the stick has an orange fluid floating above the thick pink fluid, this is the orange stick.

If the floating fluid is pink-on-pink, this is your red stick.

If you don’t see another fluid floating over the thick pink liquid, that’s the pink color.

All in all, excellent deal on these sticks and I’m pleased with them.

Oh, they also come with a bunch of lanyards.

UPDATE:

It’s been about 10-11 hours since I cracked them. The pictures I have attached are at that point. I tried to adjust my camera settings to reflect what they look like in a dark room.

Basically at this point, the pink one has become purple is not much dimmer than the orange, red, and yellow one.

For illumination and seeing things:

The green is still definitely the best light. For illumination, I can still see around a room with it. Blue and yellow aren’t far behind it. Orange is pretty hard to see. Purple is worse still. Red is basically useless for illumination at this point. It still has a pretty good glow in the darkness though so it’s not like you wouldn’t be able to easily see the stick.

NOTE: This is largely because of how the human eye works so don’t blame the glowsticks. Red only activates the red cones in your eyes so essentially, you’re only seeing with a third of your vision. Green, being in the middle of the visible light spectrum, bleeds into the other spectrums a little so it activates more of your cones so you can see better. This is probably why blue and yellow are about equal since they’re on either side of green. Red and pink/purple are on the opposite edges.

Love these! They are great to carry in car, in your backpack or in the house for when you need some light that doesn’t need batteries, blow out or set things on fire. One gives a good amount of light and stays bright for hours. A real win during extended power failures!

I’ve bought these glow sticks several times for my son because he sleeps better at night with one by his bed. And I sleep better at night without him in my bed. ( he fears power outages) They last long and work great! They can be a little hard to “snap” sometimes but always work, never leak and always last at least 24 hours or more.

I really like these glow sticks! They’re super bright, just like the description said, and they still glow after 12 hours (you can see in the photo). The color does fade a little over time, but they still last longer than expected. The shipping was a bit confusing—the package arrived earlier than the original estimate, but not on the exact day it said. Overall, really happy with them and would recommend!

These are decent lights. The colors are fun, they’re reasonably bright and they’ve lasted as long as I’ve needed them to. This makes a great party pack.
The lights are not individually packaged. They lose “freshness” out of the foil pack, so stashing these in travel bags or vehicle kits isn’t a long-them option.
Still, they worked great as trick-or-treating safety lights and sleepover decorations.
