4. Setup and Installation

Installation of these low voltage LED bulbs is straightforward. Always ensure the power source is disconnected before beginning installation.

4.1 Wiring Guide for 12V-24V DC Systems

1. AC Grid with DC Transformer: Connect the 120V AC grid to a 12V-24V DC/12V AC transformer. An optional DC dimmer can be installed between the transformer and the LED bulb.
2. Solar Panel System: Connect the solar panel to a solar controller, then connect the solar controller directly to the 12V-24V DC LED bulb.
3. AC Grid with DC Dimming Transformer: Connect the 120V AC grid to an optional AC 120V dimmer, which then connects to a 12V DC dimming transformer. The transformer then powers the 12V-24V DC LED bulb.
4. Battery Power System: Connect the battery to an ON/OFF switch, which then powers the 12V-24V DC LED bulb.

4.2 Installation Steps

1. Verify Power: Ensure the power supply to the fixture is turned off at the circuit breaker or switch.
2. Check Voltage: Confirm that the fixture's voltage matches the bulb's requirement (12V-24V DC).
3. Screw in Bulb: Carefully screw the LED bulb into the E12 candelabra base socket until it is snug. Do not overtighten.
4. Restore Power: Turn on the power supply to test the bulb.

These bulbs are designed for safe and easy installation, automatically adapting to the positive and negative poles of DC wiring.

5. Operating Instructions

Once installed, operating your LED candelabra bulb is simple:

• Power On/Off: Use the existing switch connected to your low voltage system to turn the light on or off.
• Instant Illumination: The bulb will provide full brightness immediately upon activation, with no warm-up time or flickering.
• Dimming (if applicable): If your system includes a compatible 12V DC dimmer as shown in the wiring guide (Figure 5), you can adjust the brightness level. Ensure the dimmer is specifically designed for low voltage DC LED applications.

6. Maintenance

These LED bulbs require minimal maintenance due to their long lifespan and durable construction.

• Cleaning: Ensure the power is off before cleaning. Gently wipe the bulb with a soft, dry cloth to remove dust. Do not use liquid cleaners or abrasive materials.
• Heat Dissipation: The bulb is designed for efficient heat dissipation, contributing to its long life. Ensure adequate air circulation around the bulb within the fixture.
• No User-Serviceable Parts: The bulb contains no user-serviceable components. Do not attempt to open or repair it.

7. Troubleshooting

If you encounter issues with your LED bulb, refer to the following troubleshooting steps:

• Bulb Not Lighting:
  • Ensure the power supply to the fixture is on.
  • Check that the bulb is securely screwed into the E12 socket.
  • Verify that the power source is providing the correct voltage (12V-24V DC).
  • Inspect wiring connections for any loose or damaged wires.
  • Test the bulb in another compatible fixture, if available, to rule out a fixture issue.
• Bulb Flickering:
  • Ensure the power supply is stable and within the 12V-24V DC range.
  • If using a dimmer, ensure it is a compatible DC dimmer designed for LED low voltage applications. Incompatible dimmers can cause flickering.
  • Check for loose connections in the wiring.
• Bulb Appears Dim:
  • Verify the input voltage is sufficient (closer to 24V DC will provide brighter output than 12V DC, though both are within operating range).
  • If a dimmer is in use, ensure it is set to maximum brightness.

If these steps do not resolve the issue, please refer to the Support section.
