XLG Series

The Constant Power Revolution

In the professional LED lighting sector, every installer and project designer faces a familiar dilemma: is it possible to achieve industrial-grade quality without disproportionate cost? For years, the answer was no. Premium drivers delivered reliability, but at prices that significantly inflated every project. Budget alternatives, meanwhile, compromised lifespan and installation safety.

The Meanwell XLG series breaks this cycle for good. Engineered from the ground up with Constant Power Mode technology, it delivers full rated power across an extraordinarily wide current range. In practice, this means a single driver can power vastly different LED configurations without losing performance. The result: fewer SKUs in your inventory and maximum flexibility for every project.

Unlike conventional constant-current drivers—which limit output to a fixed current—the XLG's constant power design dynamically adjusts voltage and current to consistently maintain the rated 150W. This radically simplifies installation sizing and reduces calculation errors on-site.

Built for Hostile Environments

The XLG series is not an indoor driver adapted for outdoor use. It is a device conceived from its core for industrial and weatherproof environments. Its sealed metal housing with IP67 certification withstands temporary submersion, extreme condensation, and abrasive dust.

Surge protection rated at 6kV/4kV (per IEC 61000-4-5) makes it the benchmark choice for street lighting, façade illumination, and heavy industrial facilities where grid voltage spikes are frequent and unpredictable.

Additionally, its operating temperature range of -40°C to +90°C ensures reliable operation in extreme climates, from cold storage rooms to sun-exposed industrial rooftops.

Technical Comparison: XLG Series vs. HLG Series

Unsure which series best fits your project? This summary outlines the key differences between Mean Well's two most popular LED driver families:

XLG Series (150W) — Constant Power · Compact housing (228×68×38.8 mm) · 94% efficiency · 6kV/4kV surge protection · Built-in 3-in-1 dimming · Competitive pricing. Ideal for signage, wayfinding, and budget-conscious projects.

HLG Series (240W) — Current + Constant Power · Larger housing (244×68×38.8 mm) · 96% efficiency · 6kV/4kV surge protection · Advanced multi-mode dimming · Premium pricing. Ideal for street lighting, horticulture, and high-power applications.

Both series share global certifications (UL, CE, CB, ENEC) and the backing of Mean Well, the world's leading LED driver manufacturer with over 40 years of experience.

Frequently Asked Questions

What does "Constant Power Mode" mean in an LED driver? Unlike a constant-current driver, a constant-power driver maintains fixed output power (e.g., 150W) by automatically adjusting voltage and current. This allows powering different LED configurations without changing the power supply. Browse our full range of LED power supplies.

Is the XLG series compatible with 0-10V dimming? Yes. The XLG series features 3-in-1 dimming (0-10V, PWM, and resistance) with an isolated circuit, enabling safe and complete control of luminous intensity.

Can I use the XLG-150 in permanent outdoor installations? Absolutely. Its IP67 certification and 6kV/4kV surge protection make it ideal for outdoor and industrial environments, alongside other Meanwell models in our range.

What is the main difference between the XLG and HLG? The XLG offers constant power in a more compact and cost-effective format, while the HLG combines constant-current and constant-power modes with higher efficiency, making it ideal for high-power projects such as street lighting.

Does the XLG-150 require forced ventilation? No. Thanks to its 94% efficiency and metal housing that acts as a heat sink, the XLG-150 operates by natural convection without fans, reducing maintenance and noise.
