Glow HOTARU Flex/No batteries required/Lights up to 10 hours/Charges in as little as 1 minute/Glow in the dark marker/Glow firefly

[Overview/Features] Glow HOTARU Flex is an eco-friendly luminescent marker that can be used repeatedly and emit light for up to 10 hours without the need for batteries. The light source uses ultra-high-brightness phosphorescent pigments, which can emit light for up to 10 hours after being irradiated with sunlight for a minimum of 1 minute. *Brightness will decrease over time. [Applications] Can be used as a landmark during sudden power outages or outdoors at night such as camping. [Easy to maintain] Since no batteries are required for light emission, there are no failures caused by electronic components. Therefore, it can be used as a reliable light source even in emergencies. [Safety] Uses phosphorescent pigments that are harmless to the human body, and does not contain harmful substances such as radioactive substances, so you can use them with confidence. [Eco] Unlike traditional chemical lights, this is an eco-friendly product that is environmentally friendly because it is not disposable.

Glow HOTARU is a luminescent marker that supports nighttime visibility. Safety: The phosphorescent pigment (powder) used in the light source is harmless to the human body. You can use it with confidence as it does not contain harmful substances such as radioactive substances.

Luminescence time: The luminescence time required for Glow HOTARU Flex to emit light for 10 hours is as follows.・Sunlight (clear skies) [50,000 Lx or more],.1 minute ・Sunlight (cloudy skies) [3,000 to 50,000 Lx],.5 minutes ・Just after sunset [1,000 Lx],.10 minutes ・Flashlight ( LED light) [1,000Lx],.10 minutes ・Fluorescent light (office) [500Lx],.15 minutes ・Fluorescent light (home) [200Lx],.20 minutes Purpose of use (for reference): ・Emergency A marker for power outages (*markers for flashlights, emergency bags, etc.) - Improved visibility of camping pegs and ropes - Portable light for scenes that require delicate light Media coverage: Glow on May 27, 2020 HOTARU Flex was featured on Fuji TV's news program "Mezamashi TV" as the latest disaster prevention goods. Frequently asked questions: Question 1. Is the brightness of the emitted light constant? Answer 1. The brightness of the emitted light is the brightest immediately after dark and decreases over time. In addition, phosphorescence emits light according to the surrounding brightness. Therefore, it will emit bright light in situations where the surroundings suddenly become dark, such as during a power outage, and conversely, it will emit weaker light gradually in situations where the surroundings gradually become darker. Question 2. Is it possible to force the device to glow? Answer 2. Forced luminescence is possible. By irradiating it with strong light, it will emit light at a level that can be seen even in bright light for a few minutes, but due to the characteristics of phosphorescence, the strong emitted light will quickly subside in the evening or in a place with dim light. However, it glows brightly when it gets dark. Question 3. How bright will it be after 10 hours? Answer 3. When fully phosphorescent, it supports visibility by emitting a faint light (3 mcd/m2 or more) that allows people to see it visually in the dark. Question 4: Can it store light even when it is emitting light? Answer 4. Even when the light is being emitted, it is possible to store additional light using an LED light. Question 5. There is a gap in the phosphorescent powder (pigment) inside the tube. Is it a defective product? Answer 5. No, it is not a defective product. There is an intentional gap in the design. Luminescent powder has the characteristic that the larger the particle size, the higher the brightness. It is also a very hard substance used for things such as polishing diamonds. By creating a gap inside the tube, we prevent the powder from polishing each other, reducing the particle size and reducing brightness.
