FAQ:Q1. Is the brightness of the light constant?
Answer 1. The brightness of the light is the brightest just after dark, and it will decrease over time. In addition, the luminous glow will glow according to the ambient brightness. Therefore, it glows brightly in situations where the surroundings suddenly become dark, and on the contrary, it will glow gradually with weak light.
Question 2. Can I force the glow to the water?
Answer: 2. Forced phosphorescent is possible. It emits a high level of light that can be seen even in places for a few minutes, but due to the nature of the phosphorescence, it immediately produces strong luminescence at the evening or in dim locations around the surroundings. However, it will glow brightly when it is dim.
Q3. How much brightness is after 10 hours?
Answer 3. Glow-low-in-the-dark illumination provides visibility by illuminating the light in the dark(over 3 mcd/m²) when fully charged
Question 4. Can it glow in the dark even when it is glow?
Answer 4. Even while it is luminous, you can add additional glow to the LED light.
Question 5. Is there a gap between the phosphorescent powder (pigment) inside the tube but is defective?
Answer 5. No, this is not a defective product. Designed and intentionally spaced Glow in the dark powder is characterized by the larger diameter of the grain, the higher the brightness. It is also an extremely hard material used to polish diamonds. The gaps inside the tube are used to polish each other to prevent the particles from decreasing their brightness.
