Servo-Driven Rotating Marine Beacon with Backup Power marine
lighthouse 21 nautical miles LED Rotating Marine Beacon Light
Backup Light｜21nm｜5-year Warranty
The DX-RB21 is a high-performance LED rotating marine beacon,
designed with an integrated main/standby light structure and
engineered for use in inland waterways, coastal channels, and port
lighthouses. Combining a precision-engineered rotating platform,
high-efficiency Fresnel lens, and power-adjustable high-intensity
LED array, the DX-RB21 delivers exceptional optical performance
with a nominal range of up to 22 nautical miles.
It features advanced control capabilities, supporting infrared
remote configuration, automatic rotation and flashing, and remote
monitoring via Beidou short message, 4G, or NB-IoT communication.
The system is driven by a robust ARM-based processor, ensuring
reliable long-term operation in harsh marine environments.

FAQ
1. Is this beacon easy to install? Do I need special tools or
training?
Answer:
The DX-RB21 uses a standard 4-bolt installation pattern (430 mm
diameter) and supports both AC and DC power inputs, making it
compatible with most existing lighthouse or tower setups. No
special tools are required, and we provide a detailed installation
manual. For critical applications, remote technical support is
available.
2. What is the delivery time after I place an order? Can you ship
by sea or air?
Answer:
Standard lead time is 15–25 working days depending on quantity and
customization (e.g., communication modules, color). We support both
sea freight and air shipping, and can prepare export packaging to
meet any international logistics requirements.
3. If the main light fails, will the beacon still work?
Answer:
Yes. The DX-RB21 is equipped with a physically isolated standby LED
light that automatically activates in case of main light failure,
ensuring uninterrupted operation even during critical periods.
4. Do I need internet or power at the site to monitor this beacon
remotely?
Answer:
No fixed internet is needed. The beacon supports multiple remote
communication options such as Beidou SMS, NB-IoT, and 4G — suitable
for remote coastal or inland sites. It also accepts both AC and DC
power, and optional solar integration is available upon request.
5. Is this beacon suitable for harsh weather, like heavy rain or
snow?
Answer:
Absolutely. The DX-RB21 is designed for harsh marine environments.
With IP65 ingress protection, corrosion-resistant housing, and an
operational temperature range from -35°C to +70°C, it performs
reliably in coastal storms, winter snow, and high-humidity zones.
