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.
