Product Details

STARWELL, a professional manufacturer in China, provides quality 12-18W 300mA Constant Current LED Driver features a wide universal AC input range of 85–265V 50/60Hz, perfectly compatible with 220V mains power in most regions. It outputs fixed 300mA constant current, with a DC voltage window of 36–72V, supporting LED load power from 12W to 18W. The built-in plastic insulated housing comes with pre-wired input bare wires and a standard female DC output connector, enabling quick, hassle-free installation without extra wiring conversion. Designed for harsh operating environments, it withstands a maximum case temperature (TC) of 75°C, with an ambient working temperature limit (TA) of 50°C, effectively avoiding overheating damage during long-term continuous operation. It has passed CE safety certification and complies with international electrical safety standards.

Designed with strict thermal resistance standards (max TC 75°C, max TA 50°C) and certified with CE compliance, it integrates overheat, overvoltage and short-circuit multi-protection circuits, paired with an insulated plastic housing for heat dissipation. This compact, easy-to-install LED driver ensures consistent brightness, long service life and reliable operation for all compatible 300mA LED lighting fixtures.

12-18W 300mA Constant Current LED Driver

Three Core Advantages

1. Precise Constant Current Control with ±5% Current Tolerance

The output current fluctuation is controlled within ±5%, eliminating LED brightness decay and uneven light output caused by current instability. It protects LED chips from burnout and extends the light source service life by over 30%.

2. Ultra-Wide Compatibility & Wide Voltage Adaptation

85–265V full-range AC input works stably under unstable grid voltage fluctuations. The 36–72V DC output matches all 12–18W 300mA LED lamp boards, covering mainstream indoor lighting models to cut inventory costs for buyers.

3. High Thermal Resistance & Long Service Lifespan

With TC up to 75°C and TA up to 50°C, the internal circuit adopts heat-dissipating structural design. It runs safely in enclosed lamp housings, supporting 30,000 hours of stable working life, and integrates over-temperature, over-voltage and short-circuit multi-protection circuits.

Ideal for indoor commercial and home lighting, this STARWELL LED driver balances cost efficiency, safety and stable performance, serving as a cost-effective standard power supply choice for lighting manufacturers.
