30W & 40W L Series Waterproof Constant Voltage LED Driver

Lighting projects that operate at full brightness every day require a power supply focused on stability rather than dimming. The 30W 40W LED Driver from the KSPOWER L Series is engineered for fixed-output LED lighting, delivering consistent constant-voltage performance in indoor and outdoor environments.

Designed with a universal 100–277VAC input, this Outdoor LED Transformer supports 12V, 24V, 36V and 48V DC outputs. Its ultra-slim aluminum housing allows installation in narrow spaces, while the IP65/IP67 enclosure protects against rain, dust and moisture, making it suitable for landscape lighting, illuminated signage and architectural LED systems. UL/cUL and CE certifications help meet the requirements of North American and European projects.

Why Choose the L Series?

Built for Reliable Fixed-Brightness Lighting

Unlike dimmable power supplies, the L Series is optimized for applications where constant illumination and long operating life are more important than lighting control.

Waterproof LED Power Supply

The sealed housing protects internal electronics from rain, humidity and dust, making it suitable for both indoor and outdoor installations.

IP67 Constant Voltage Driver

Provides dependable operation in demanding environments such as building facades, landscape lighting and outdoor signage.

Outdoor LED Transformer

Ideal for projects exposed to changing weather conditions while maintaining stable DC output.

Slim Aluminum LED Driver

The compact aluminum enclosure improves heat dissipation while simplifying installation inside narrow lighting profiles and signage frames.
