What the AI looks for in Emergency Light Sticks
- Color
- Green or yellow for the most visible light and the longest useful glow. The eye is most sensitive to these colors. Red and blue look dimmer at the same output.
- Duration rating
- Choose a long-duration stick, typically rated around 12 hours, for overnight use, and a high-intensity short-duration stick for signaling. There is a trade-off between brightness and how long the stick lasts.
- Packaging and shelf life
- Buy individually foil-wrapped sticks with a printed expiration date, and replace them when they expire. Light and moisture break down the chemicals inside, and old sticks glow weakly or not at all.
- Temperature
- Expect dimmer light in the cold and a faster burn in the heat. Warm a cold stick inside your jacket. The chemical reaction speed depends on temperature.
Brands that matter
- Cyalume: The industrial and military standard for chemical light sticks.
What to avoid
- Bulk party glow sticks without foil wrapping for emergency kits.
- Sticks with no expiration or duration rating listed.
- Cutting sticks open; the contents irritate the skin and eyes.
Questions
Are light sticks safe around fuel or gas leaks?
Yes. They produce no heat or spark, which is why they are used where a flame or a switch could be a risk.
