Key Features of the XC188 Underwater Fishing Light
Four-LED 360° Light Distribution
The XC188 uses four LEDs:
- One LED at the top;
- One LED at the bottom;
- One LED on each side.
The multi-directional LED arrangement provides broad underwater visibility and helps the light remain visible even when the fishing line or rig changes direction.
The light is suitable for deep drop fishing rigs, longline fishing equipment, traps, pots and other marine fishing applications.
Water-Activated Operation
The underwater fishing light automatically switches on when it enters the water.
After the light is removed from the water and dried, it switches off automatically. The water-activated design reduces unnecessary power consumption and does not require a separate external switch.
Long Operating Time
The built-in 3.7V 3000mAh lithium battery supports extended fishing operations.
Typical operating times are:
- Solid mode: approximately 1,000hours;
- Strobe mode: approximately 4,000–5,000 hours.
Actual operating time may vary depending on LED color, operating mode, water temperature and product configuration.
IP68 Waterproof Housing
The transparent housing is manufactured from durable Bayer ABS material and sealed for underwater use.
The reinforced shell and waterproof sealing structure are designed to resist water pressure in deep-sea environments. The product has an IP68 waterproof rating and has passed customer testing at a depth of 1,000 meters.
Multiple Line Attachment Points
The housing includes multiple attachment holes and side locking structures to help secure the light to fishing lines and rigs.
The line holes are suitable for approximately 1.8–3.0 mm monofilament fishing line, depending on the installation method.
The multi-point attachment design helps reduce accidental loss, line twisting and unnecessary movement during deployment.
Compact and Lightweight Design
The XC188 measures approximately 3.5 × 9 cm and weighs about 51 g.
Its compact design helps reduce resistance during deployment and allows the fishing rig to descend efficiently into deeper water.
