Main Raw Materials:  

Rare earth long-lasting afterglow night-light powder, polystyrene resin

 1. Nightlight powder

A high-tech self-luminescent product made from a rare earth metal activated alkaline earth aluminate and silicate. Its function is to absorb light and store it for later use, emitting light in the dark. It has a strong ability to absorb short-wave visible light with a wavelength of less than 450 nanometers. By absorbing various natural or artificial light, it achieves self-luminescence in the dark state, and can be used indefinitely. This luminescent material has a high initial brightness, a smooth luminescence curve, and a long afterglow duration. The afterglow luminescence time and brightness of the long-afterglow night-light powder are higher than those of traditional zinc sulfide storage powders, and it has a faster absorption effect on sunlight and ultraviolet light, and can be recycled.

 Polystyrene resin

Polystyrene (Polystyrene, abbreviation PS) refers to a polymer synthesized by the free radical polymerization of styrene monomers. It is a colorless and transparent thermoplastic plastic, resistant to corrosion and durable. It has excellent heat stability and flow during melting, easy to mold and process, especially easy to inject molding, suitable for mass production. The molding shrinkage rate is small, and the size stability of the finished product is good. It does not emit harmful substances, and its chemical properties are stable. The molecular structure itself does not absorb water, and it has superior water resistance and moisture proof properties. It is widely used in the optical industry, with good transparency, can be used to manufacture optical glass and optical instruments, and can also be used to produce transparent or bright colors, such as lampshades, lighting equipment, etc. At the same time, in the production process, it does not produce harmful gases, and there is no waste water produced. The solid waste formed can be recycled and reused, and it is a high-quality environmental protection product.

Nightlight Stone Frequently Asked Questions:

1. Q: Why does nightlight stone glow?
Answer: Nightlight stones are made of nightlight material and resin. They absorb energy from light and release it in the dark. Nightlight stones are also known as storage stones; they do not glow on their own, but only after absorbing light. The glow effect is not obvious in the day or in bright places, but it can be seen only in relatively dark places. While absorbing light, they also glow. Over time, the nightlight effect will gradually fade. Nightlight is temporary, not lasting, but it can be recharged and reused repeatedly.

2、Q: How can one make the nightlight stone glow?
Answer: No need to power on. It is a photoluminescent product that only glows when it absorbs and stores light. The night light stone you received from the courier does not glow because it did not absorb light in the shipping box. Just place it under sunlight or light for 5-10 minutes and it will re-glow.

3、Q: What can nightlight stone be used for?
Answer: Lay on the walkways, flowerbed edges, or fill the plant pots and fish tanks with night-light stones, making your garden or courtyard absolutely unique and cool! Also suitable for home decoration, art and crafts, DIY gifts, night lights, etc.

4、Q: Is nightlight stone safe?
Answer: They are made from eco-friendly materials through injection molding at high temperatures, which are safe and non-toxic.

Question: If a nightlight stone has been exposed to the sun for a whole day, will it still not light up at night?

Answer: Nightlight stones absorb light to emit light, then absorb light again to emit light. They also begin to emit light during the storage of light. If the stone absorbs light during the day, after the high-brightness period of nightlight, and there is no light source to absorb at night, it can only see slightly weaker light. However, if you turn on the light to illuminate the stone and then turn off the light, you can see a very bright nightlight.

Question: Are there nightlight stones that glow for a long time and are very bright?

Answer: Energy cannot be created out of thin air, nor can it disappear without a trace. It can only be transferred from one object to another, and the form of energy can also be converted. This process is known as the conservation of energy. Nightlight stones are also subject to this principle. As long as they are continuously exposed to light, they will continue to glow. However, in the evening or in dark places, without light exposure, the stored light will gradually run out. The brightness can vary from very bright, bright, to dim, average, faint, to non-existent... until they are exposed to light again, they will glow once more. The decay of luminescence (afterglow) consists of an initial rapid decay followed by a slower decay. The duration of the luminescence (afterglow) is related to the number of stored electrons (light energy) and the amount of energy absorbed.

 Nightlight stones do not show their luminescence clearly in the day or in bright environments. They only reveal their nightlight effect in relative darkness! Our nightlight materials are eco-friendly and can emit fluorescent light (like firefly light) in the dark. They are not comparable to electric light sources! Do not mistakenly think that nightlight can compete with light.

7、Q: What is the difference between your night light stone and others?

Answer: We areHigh brightness night lightThe difference lies inluminous timeandNight Light IntensityCompare it with a cheaper one and you'll see the difference. It's not about being afraid to compare goods, it's about not knowing how to appreciate them. Compare quality at the same price, and price at the same quality.
