Overview

1. Function Description
2. Important Technical Specifications
3. Usage Features
4. Maintenance Features

The F.I.T. Bunny LED is a versatile and robust underwater lighting system designed for various applications, including photography and general illumination. Its modular design and comprehensive features make it suitable for both amateur and professional users.

Function Description

The Bunny LED serves as a powerful and adaptable light source, primarily for underwater environments. It features two independent LED heads, each capable of producing 300 lumens of white light with a 110-degree beam angle. This dual-head design allows for flexible lighting setups, enabling users to control each light independently for optimal illumination. The device is powered by a single 18650 Li-Ion battery, ensuring a compact and portable form factor.

The core functionality revolves around its ability to provide adjustable brightness levels (100%, 50%, 25% intensity) and independent control over each LED head. This allows users to fine-tune the lighting to suit different scenarios, whether it's for wide-angle illumination or more focused lighting. The device also incorporates safety features such as overheating prevention and low battery protection, which automatically adjust brightness or turn off the light to preserve battery life and prevent damage.

The Bunny LED's construction includes a "Light Head" with two LED outputs, a "1/4 Loc-lin" attachment point for mounting, a "Left Button" and "Right Button" for control, a "Power Indicator" to display battery status, a "Hot Shoe Base" for accessory mounting, and a "Battery Cap" for battery insertion. The "Flood Output (2LED)" indicates its capability for broad illumination.

Usage Features

Installing the Battery:

1. Turn the Bunny LED cap counter-clockwise to open.
2. Insert the 18650 battery, ensuring it faces the correct direction as shown in the diagram.
3. Align the battery compartment with the cap and close it by turning clockwise until fully sealed. It is crucial to close the cap completely to prevent flooding.

Operation (ON/OFF and Brightness Control):

• Turning ON:
  • To turn on the left LED (default 100% intensity), press the left button for 2 seconds.
  • To turn on the right LED (default 100% intensity), press the right button for 2 seconds.
  • Both LEDs can be controlled independently.
• Adjusting Brightness (with light ON):
  • For the left LED, press the left button for 1 second to cycle through brightness: 100% → 50% → 25% → 100%.
  • For the right LED, press the right button for 1 second to cycle through brightness: 100% → 50% → 25% → 100%.
• Turning OFF:
  • If one side of the LED is on (or in temperature protection mode, or low volt status), press the button corresponding to the active LED for 3 seconds to turn it off.
  • If both LEDs are off, or with light off, press any button for 5 seconds to turn off both LEDs (one LED will turn off first, then the other).

Overheating Prevention: The Bunny LED is equipped with a temperature sensor. If the unit starts to overheat, it automatically switches to a lower brightness mode to prevent damage.

Battery Status Indicator: The device provides 4 battery status indications:

• Green: Full
• Yellow: Half
• Red: Low
• Blinking Red: Extremely low (light will turn off automatically after 10 minutes).

Low Battery Protection: When the battery reaches a low level (indicated by a red LED), the Bunny LED enters a low brightness mode to conserve power. If the battery becomes extremely low, the light will automatically turn off after 20 minutes to prevent over-discharge.

Using the Charger:

1. Ensure the 18650 battery is correctly inserted into the charger.
2. Plug the charger cable into a power source. The indicator will blink during charging.
3. The indicator will turn green once charging is complete (approximately 3 hours).
   • The Micro USB port on the charger is for a 5V/1A Micro USB charger.
   • The power indicator shows battery status.
   • The USB output port can charge other 5V 1A devices via a USB cord.
   • To protect the battery and extend its life, avoid charging for more than 12 hours.

Maintenance Features

Grease Application: Use the provided grease to lubricate the O-Rings. This ensures smooth operation and a proper seal. Before application, remove any dirt or hair from the O-Ring and its groove.

Changing of O-Ring: Regularly inspect the O-Rings for any deformation, damage, or expansion. If found, replace them with the provided spare O-Rings. Avoid using sharp objects as tools when removing O-Rings. Clean the O-Ring grooves thoroughly before installing new O-Rings and apply grease. Protect the O-Rings from outer debris.

Important Notes:

• Only use the specified battery type (18650).
• Never attempt to open the battery cap underwater.
• Remove the battery if the Bunny LED will not be used for a prolonged period.

Product Warranty:

• Quality Assurance: For 15 days from the retail purchase date, your local retailer will exchange the product for a new one if a hardware defect occurs.
• Warranty Period: The warranty is valid for 1 year, offering free servicing for any problems (batteries are warranted for 3 months). Shipping and handling charges may apply if the warranty is invalid.
• Exclusions: The warranty does not cover:
  1. Modification, damaged, or dismantled units.
  2. Wrong operation (e.g., using the wrong type of battery).
  3. Short circuit due to flooding.
  4. Natural occurrences beyond human control.

Troubleshooting Guide:

• LED fails to light up:
  • Check battery direction.
  • Check if the battery is low on power.
  • Check if the cap is fully closed.
• Green LED lights up the moment charging commences:
  • Ensure the battery is installed properly.
  • Place the battery on the right side of the charger.
  • Verify contact between the charger and battery.
• Water found inside the light:
  • Check the O-Rings for dirt or improper installation.
