ultra-high brightness Glow in The Dark powder
1. Differences Between Ultra-High Brightness and Ordinary Glow in the Dark Powder
Compared with ordinary long-afterglow luminous powder, the biggest feature of Ultra-High Brightness luminous powder is the improvement of brightness and the extension of afterglow time. Ultra-High Brightness luminous powder has higher initial brightness and longer continuous luminous time. Under the same irradiation conditions, its luminous effect is significantly better than ordinary types.

3. Luminous Color Options
At present, GlowUp®‘s Ultra-High Brightness grades mainly provides two colors: Yellow-Green and Blue-Green. These two colors have become the mainstream choice in the market due to their wide applicability and can meet the needs of most customers. We are developing a sky blue super bright formula. This is a more attractive color. After the unremitting efforts of the R&D team, significant progress has been made and it will soon be available on the market. In the future, we will provide customers with more color options to meet diverse needs.
4. How to Ensure a Reliable Supply of Ultra-High Brightness Grade?
- Selectin Premium Raw Materials
We strictly screen high-quality raw materials, such as 99.999% strontium carbonate (SrCO₃). This high-purity raw material greatly improves the luminous brightness and significantly enhances the luminous sustainability of the luminous powder. Through strict raw material screening, we ensure that each batch of basic materials can provide reliable quality assurance for the production of GlowUp® powder.
- Professional Technical Team
Our technical team consists of several experts in the fields of fundamental and fine chemistry, with core members boasting over 25 years of experience and other members having at least 8 years of professional expertise. With a deep understanding of glow in the dark powder luminescence mechanisms, our team focuses on continuous innovation and process optimization. Through extensive testing and experiments, we have developed multiple breakthrough formulas.
- Advanced Production Equipment
We use kilns that are independently designed and built, with its structure and temperature control system carefully optimized. The rational internal structure ensures the efficiency and stability of the firing process of glow in the dark powder. Precise temperature control can effectively reduce the impact of high temperatures on the brightness, and can maximize the retention of the powder’s luminenscence and duration.
Our post-processing utilizes industry-leading automated equipments, including crushing, milling, and sieving machines. By ensuring the uniformity of particle distribution and stable luminescence performance, it can achieve excellent performance of luminescent powder in end products.
The use of high-precision granularity and brightness testing equipment and maintaining a stable testing environment is one of the decisive factors in ensuring the stable quality of Ultra-High Brightness luminous powder. The accuracy of the brightness of luminous powder has extremely strict requirements for the stability of testing conditions. As a highly sensitive numerical value, the brightness index is easily affected by many factors, including the precision of testing instruments, sample size, exposure duration, room temperature etc. Even minor variations can significantly impact results. Following the international standard DIN67510, we utilize standard testing containers and automated processes to minimize human interference. At the same time, we maintain constant temperature conditions during testing to ensure accuracy and reliability of the results.
- Process and Technology Optimization
We continuously refine our manufacturing processes, such as improving sintering techniques to enhance crystalliazation quality of the particles, resulting in higher brightness and greater luminescence efficiency.
Advanced temperature and time control technologies during high-temperature synthesis ensure the structural integrity of glow powder particles, maintaining superior brightness and luminescence performance.
In the production process, we use precise temperature and time control technology to ensure the structural integrity of luminous powder particles during high temperature synthesis to maintain higher brightness and luminous effect.
Through these measures, a continuous and stable production of Ultra-High brightness glow powder can be achieved, which provides a strong guarantee for on-time delivery and quality assurance.
