The Haikelite RA40 represents the peak of modern flashlight engineering — a fusion of immense output, intelligent control, and professional reliability, designed to deliver overwhelming illumination for the most demanding users. It is not merely a flashlight; it is a powerhouse of light, capable of producing an astonishing 35,000 lumens, combining precision and power in a rugged, thoughtfully crafted body built to withstand real-world challenges.

At the heart of the RA40 lies an array of forty HK3535 high color rendering LEDs, delivering a balanced 5000K neutral white output. The light they produce is rich, natural, and highly accurate, achieving a CRI above 95, which means it renders colors with true-to-life fidelity. Whether it’s used for professional photography, outdoor exploration, or technical work, the RA40 provides light that restores the genuine appearance of objects, reducing visual strain even during long-term use. The beam pattern is wide, consistent, and warm, offering both intensity and comfort — a rare combination in a light of this magnitude.

The RA40’s impressive performance is supported by a 46950 high-capacity lithium power cell, providing enormous energy reserves for extended operation. This Grade A high-capacity battery ensures long-lasting performance with exceptional discharge efficiency, allowing the flashlight to sustain its power output across various brightness levels. Charging is simple and efficient through the Type-C bidirectional fast-charging port, which supports multiple fast-charge standards including 5V 3A, 9V 2A, Huawei SCP 5V 4.5A, and PD protocols. The flashlight can also function as a power bank, enabling users to charge other devices in the field — a feature that enhances its practicality during expeditions, emergencies, or professional work.

The intelligent power management system keeps the user informed at all times through a battery level indicator integrated into the switch. When the voltage drops below 3.2V, a blue light begins to flash; when it falls below 3.0V, the indicator turns red, signaling that a recharge is needed. At 2.8V, the RA40 automatically shuts off to protect the battery from over-discharge. This system guarantees both safety and longevity, while the integrated circuit ensures a stable current output for consistent brightness.

Operation is smooth and intuitive, built around Haikelite’s infinitely dimmable system. When the light is on, pressing and holding the main switch gradually adjusts brightness — releasing the button locks the level, and pressing again reverses the dimming direction. This stepless ramping provides absolute control over light intensity, allowing users to tailor illumination to any situation, from delicate close-up work to full-scale area lighting. For those who prefer discrete steps, a triple-click activates the stepped ramping mode, providing preset levels for quick selection.

For moments that require sheer power, the RA40 features an instant Turbo mode, accessible with a double-click from any state. This unleashes the full 35,000-lumen output, flooding large spaces with light that rivals daylight itself. When the internal temperature reaches 55°C, the flashlight’s temperature control system automatically reduces output to 4,500 lumens to maintain safe operation, ensuring consistent light for extended periods — up to four hours of sustained use. Once the temperature drops below 48°C, the output automatically increases again. This intelligent cycle allows the flashlight to maintain maximum performance without risk of overheating, a feature critical for such high-power devices.

Additional modes such as strobe and SOS can be accessed through a sequence of double-clicks after entering Turbo, providing effective tools for signaling or emergency situations. The lockout function, activated by pressing and holding for three seconds when the flashlight is off, prevents accidental activation during transport. To unlock, the same action can be repeated. This level of control and customization gives users complete command over the RA40’s extraordinary capabilities.

In terms of construction, the RA40 reflects Haikelite’s commitment to durability and performance. The body is made from 6063 aviation-grade aluminum alloy, finished with Type III hard-anodized coating for maximum resistance to wear and corrosion. The lens is reinforced glass, offering excellent impact and thermal resistance, while the silver-plated copper alloy springs inside the circuit ensure low resistance and optimal energy transfer. Despite its robust build, the design remains ergonomic and well-balanced, weighing 628 grams without packaging and 1,450 grams gross weight, with a structure that feels solid and comfortable in the hand. The flashlight measures 175mm in length, with an 87mm head, 55mm tail, and 51mm handle diameter, achieving the right balance between size and functionality for professional use.

Every aspect of the RA40’s operation reflects attention to safety and detail. Users are advised to avoid direct exposure to eyes or reflective surfaces due to its extreme brightness. The head naturally heats up quickly when used in Turbo mode, which is normal for such high-power illumination; Haikelite includes clear reminders to prevent accidental burns and recommends caution when handling during extended use. When left unused for long periods, it’s best to remove or loosen the tailcap to prevent minor parasitic drain.

The Haikelite RA40 is not just about power — it’s about controlled, intelligent performance. From its flawless beam quality to its exceptional construction, it stands as a professional-grade lighting tool for photographers, search-and-rescue teams, engineers, and outdoor enthusiasts. It delivers unprecedented brightness, robust thermal control, and advanced battery management, all within a sleek, precision-engineered body that reflects the best of Haikelite’s craftsmanship.

In the world of ultra-bright flashlights, few achieve this level of refinement. The RA40 demonstrates that massive output can coexist with elegance, safety, and efficiency — a beacon of engineering excellence that brings daylight into darkness and redefines what portable illumination can achieve.

Safety precautions
● The product is a high-power high apparent finger torch apparent finger CRI>95, can be applied to, fill light photography [more perfect restore the object's original colour] outdoor lighting light colour warm long time use does not hurt the eyes.
● The torch battery is 46950 model high capacity power battery, the battery features high capacity and strong power, the battery used is Grade A
● When the battery voltage is too low, please charge it in time. The flashlight has a low battery prompt(when the voltage is lower than 2.8V, the flashlight will enter the protection function and turn off the flashlight).
● Do not shoot directly into the eyes of people or animals,  and do not irradiate moving vehicles or flammable objects. It is normal for the head to heat up quickly, please use it with caution to prevent hot hands.
● Unscrew the battery tube and insert the one 46950 cells. Note that the Lamp require button-top type cells.Take care to observe thecorrect polarity for each cell.
● Double check the polarity every time before closing: The lower seated batteries must point with plus (nipple)towards the head. The higherones must look with plus to the open back! All flat ends look at the springs. Screw the battery tube back. The RA40 will flash once when electrical contact is made. Continue to tighten the battery tube to a gentle stop. Do not overtighten.
● There is a very small drain on the battery while OFF. This should not be of any concern, but we recommend removing the cells (orpartially loosening the tail-cap)if the RA40 will not be used for several months.
● Safe use reminder: This product is a strong light high-power torch. After the battery isfully charged, it will be switched on for about 45 seconds and then downshift. The head of thelight will heat up quickly.  In the hot environment, the torch temperature can easily exceed 55 degrees. Warm reminder of anti-scald.
