Energy-saving and environmentally friendly.
Featuring an aluminum heat sink housing, the wick features a 360-degree luminous design. It comes with a PC lampshade and is IP66 waterproof. It offers sufficient power without false claims. Multiple voltage options are available.
It utilizes a constant-current IC power supply with a wide-voltage drive design and complies with CE and RHOS certifications.
1. Lamp Base Type: BA15d
This is a very common dual-contact, bayonet-style lamp base that secures by twisting approximately 1/4 turn after insertion.
The "d" designates the two contacts, one thicker and one thinner, with a polarization design to prevent mis-insertion and ensure correct installation orientation.
This is the main difference between it and the BA15s (which has identical contacts).
Operating Voltage: 10-30VDC and 110V/240VAC
This indicates that it is designed for DC power environments and is ideal for 12V or 24V DC battery-powered systems in boats, cars, RVs, and other applications.
Light Source Type: LED (Light Emitting Diode)
It contains an array of multiple yellow LED chips, providing high-brightness, uniform light.
2. Key Features and Benefits
Energy Efficiency: LED technology converts the majority of electrical energy into light rather than heat, consuming far less power than traditional incandescent bulbs.
Extremely Long Life: LEDs lack filaments, are shock and vibration resistant, and offer a lifespan of tens of thousands of hours, significantly reducing maintenance and replacement frequency.
Low Voltage Safety: Operating at a safe voltage, they avoid the risks associated with high voltage, making them particularly suitable for humid marine environments.
Plug and Play: A direct replacement for traditional incandescent bulbs, they can be upgraded without changing the existing lamp holder or wiring.
3. Typical Application Scenarios
This bulb is primarily used in applications requiring low-voltage, high-reliability indicators:
Marine: Dashboard indicators, switch backlights, navigation lights, anchor lights, etc., both inside and outside the cabin.
Automobiles/Trucks: Dashboard indicators and switch button lights.
Industrial Equipment: Status indicators for control cabinets and control panels.
RVs/Campers: Indicators for various internal devices.
Designed for DC power systems such as marine systems, the BA15d interface LED indicator lights offer energy-saving, long life, safety,
and reliability, making them a perfect modern upgrade for traditional incandescent bulbs.
