SFT-42R Circular Emitting Surface, Reshaping the Flashlight Lighting Experience
1. Unique Circular Emitting Surface, Uniform and Soft Light
The SFT-42R’s circular emitting surface design is ingenious. Luminus has consistently invested in LED technology research and development, and its circular chip technology has obtained numerous patents. These patents not only recognize technological innovation but also build a solid technological barrier. From chip structural design to manufacturing process optimization, Luminus’s R&D team has conducted in-depth research. Through patented technology, they have ensured the superior performance of the circular chip in terms of luminous efficiency, stability, and other aspects, laying a solid foundation for high-end flashlight applications. High-end flashlights have extremely high requirements for beam quality. Luminus’s circular chips are perfectly compatible with commonly used circular optical components in flashlights, such as reflectors and lenses. High-end flashlights often need to have powerful long-range capabilities. Luminus’s circular chips can provide a narrower beam angle, meaning that the light can be projected more concentratedly over a greater distance. When the light emitted by the chip passes through a carefully designed reflector or lens, a longer beam distance can be achieved. Taking some high-end tactical flashlights equipped with Luminus circular LEDs as an example, their maximum range can reach hundreds or even thousands of meters. They can easily illuminate distant targets in dark environments, playing a crucial role whether for orientation during outdoor adventures or long-range reconnaissance in law enforcement and military operations.

Suitable for flashlights, search and rescue lights, automotive aftermarket work lights, etc.

2. A new favorite in flashlight lighting, versatile for multiple scenarios
The characteristics of the SFT-42R make it an ideal light source in the flashlight field. In daily life, holding a flashlight equipped with the SFT-42R provides reliable illumination with its stable and uniform light, whether walking at night, walking the dog, or encountering emergencies such as power outages. In outdoor activities such as camping and hiking, the SFT-42R’s advantages are even more pronounced. It not only illuminates the path but also provides ample light to the surrounding environment, making it easier for users to observe their surroundings. Furthermore, due to its circular light-emitting surface design, the light reflects and scatters more naturally, creating a lighting effect closer to natural light, making the outdoor environment appear more realistic and comfortable.
SFT-90X Industry-leading Large Chip, Forging a King of Range
1. Large Chip, the Cornerstone of Exceptional Performance

2. Ultra-long range, exploring infinite possibilities
Thanks to its large chip, the SFT-90X boasts an astonishing range. In practical applications, such as outdoor adventures and search and rescue operations, its powerful beam easily penetrates darkness, reaching extremely long distances. Imagine, in a deep valley or vast wilderness, the beam emitted by the SFT-90X clearly illuminates targets 2km or even further away, giving users a field of vision far exceeding that of ordinary people, allowing them to confidently navigate paths or detect potential dangers. It’s like a sharp sword in the darkness, cleaving through the night to clearly reveal distant scenes.
3. High cost-performance ratio, combining power and affordability
While possessing powerful performance, the SFT-90X also offers excellent cost-performance. Luminus effectively controls costs without sacrificing product quality by optimizing manufacturing processes. This makes the SFT-90X stand out among similar products, providing users with a high-quality option that allows them to enjoy top-notch lighting effects without incurring excessive costs. Whether for professional lighting equipment manufacturers or individual consumers demanding high-quality lighting, the SFT-90X is an extremely attractive option due to its exceptional cost-effectiveness, enabling more people to enjoy the convenience brought by advanced lighting technology.
