MEAN WELL LPF-40-24 24VDC 40W Class 2 LED Driver - IP67 Encapsulated

In this review the MEAN WELL LPF-40-24 is assessed as a compact, weatherproof LED driver aimed at installers and DIYers who need a reliable 24V DC Class 2 supply. The bottom line: it delivers a stable 24VDC output at up to 1.67 A and 40 W in an IP67 encapsulated enclosure, making it suitable where moisture resistance and consistent power are priorities. Our review focuses on build, electrical range and practical installations rather than marketing claims.

Key Features

• 24VDC Output: Provides a steady 24 volt DC supply that suits a wide range of LED strips and low-voltage luminaires for predictable light levels.
• 1.67 A Current Capacity: The 1.67 amp rated output supports mid-power LED runs without frequent trips or overloads when sized correctly.
• 40 W Maximum Power: With 40.08 watts available the driver covers moderately sized lighting circuits and avoids overspec waste in compact installs.
• Wide Input Range: Accepts 90 to 305 VAC and 47 to 63 Hz, so it works across mains conditions and international sites without additional converters.
• IP67 Encapsulation: The sealed housing protects the electronics from dust and immersion, simplifying outdoor, damp or exposed installations.
• Class 2 Safety: Engineered as a Class 2 power supply to meet regulatory expectations for low-voltage lighting applications.

Who It's For

The LPF-40-24 is best for contractors, outdoor lighting installers and hobbyists who need a compact, robust 24V LED driver that tolerates wide input voltages and wet conditions. It is particularly useful for pathway, sign, or facade lighting where the IP67 rating reduces enclosure needs.

Those who need higher current for long runs of high-density LED tape, on-board dimming electronics, or isolated outputs should look at higher power alternatives; likewise, projects requiring integrated dimming protocols or multiple outputs will need a different model.

Pros & Cons

Pros

• Reliable regulated 24V output that keeps LEDs stable under varying mains conditions.
• IP67 encapsulation makes it practical for outdoor and damp-location installs without additional enclosures.
• Wide 90-305 VAC input range reduces compatibility concerns for international use.

Cons

• Single-output 40 W capacity limits very long runs of high-power LED tape or multi-zone projects.
• No integrated dimming interfaces, so external dimmers are required for brightness control.

Specifications

Our Verdict

The MEAN WELL LPF-40-24 is a sensible choice for anyone who needs a weatherproof, dependable 24V LED driver for moderate loads. It offers good value when IP67 protection and a wide input range matter more than dimming features or multi-output flexibility, making it a practical component for many outdoor and commercial lighting installs.

Frequently Asked Questions

Is this driver safe for outdoor installation?
Yes. The IP67 encapsulated housing protects against dust and immersion, making it suitable for exposed or damp locations when installed according to local codes.

What size LED runs will it support?
It supplies up to 1.67 A and 40 W at 24V, so it is best for moderate-length LED strips or individual luminaires within that power envelope.

Does it include dimming features?
No. This model is a fixed-output Class 2 driver and does not include built-in dimming; external dimmers or controllers are required for brightness control.
