Core Features: Low Temperature, Smokeless and Safer
As a new eco-friendly fireworks product, cold light smokeless fireworks produce almost no visible smoke, with flame temperatures ranging from 100°C to 300°C and much lower than traditional fireworks. This significantly reduces fire risks and environmental pollution.
Chemical Formulation: Smoke and Temperature Control from Raw Materials
These fireworks use metal-organic complexes as luminescent centers, supplemented by low-smoke oxidants, and polymer materials as fuel matrix and binder. Polymers burn to produce water vapor and carbon dioxide instead of a large number of solid particles, effectively suppressing smoke formation.
According to the 2025 Environmental Protection Cold Light Fireworks Technical White Paper, the average smoke density index (SDR) is 8.7, far lower than the 62.3 of traditional fireworks.

Luminescence Mechanism: Color Development via Low-Temperature Ion Transition
Cold light smokeless fireworks emit visible light of specific wavelengths through electronic transitions of excited metal ions. Strontium compounds emit red light (600–650 nm), and copper compounds emit blue-green light (490–520 nm). Trace rare earth elements are added as fluorescence enhancers to improve luminescence efficiency and color stability.
The peak heat release rate is below 15 kW/m², much lower than traditional fireworks, which is the direct reason for its "cold light" feature.
Safety and Environmental Protection: National Standard Compliant and Ultra-Low Emission
The formulation eliminates high-risk components such as chlorates, sulfur and charcoal, making transportation, storage and use safer. Combustion products are mainly CO₂ and H₂O, without benzene, PAHs or excessive heavy metals.
Biodegradable paper tubes or PLA casings are used to further reduce plastic pollution, achieving intrinsic safety and eco-friendliness.
