The MEAN WELL HLG-40H series is a 40W AC-to-DC LED driver family featuring both constant-voltage (CV) and constant-current (CC) output modes. It is designed for LED street lights, high-bay fixtures, parking lighting, fishing lights, and greenhouse lighting.
It accepts universal 90~305VAC input (127~431VDC) and provides nine fixed output voltage options: 12V, 15V, 20V, 24V, 30V, 36V, 42V, 48V, and 54V. With peak efficiency up to 89.5%, the driver uses a fanless design and operates at case temperatures from -40C to +80C under natural convection.
The metal enclosure carries IP67 or IP65 ratings depending on the version and is certified to UL8750 Type HL for Class I Division 2 hazardous location luminaires. Five function versions are available: Blank (fixed output, IP67), A (internal potentiometer adjustment, IP65), B (3-in-1 dimming, IP67), AB (pot adjustment + 3-in-1 dimming, IP65), and D (timing dimming, IP67).
Protection includes OVP, OTP, short-circuit hiccup, and over-current constant-current limiting. The driver withstands 4KV line-to-ground and 2KV line-to-line surge, complies with global lighting safety and EMC standards, and is backed by a 7-year warranty.

HLG-40H is a CV+CC dual-mode driver with 9 fixed output voltage options (12V~54V), IP67/IP65 sealing, Type HL, and up to 7-year warranty. ELG-40/45 are voltage-output or constant-current drivers with different form factors and feature sets.
Yes. Each voltage model has a specified constant-current range (e.g., 14.4~24V for HLG-40H-24). If the LED string forward voltage falls within that range, the driver operates in constant-current mode. It can also power LED modules with built-in constant-current drivers in constant-voltage mode.
Blank for simple fixed-output outdoor luminaires. A-Type for fixtures needing voltage/current tuning via internal pot. B-Type for smart lighting with 1-10V/PWM/resistor dimming. AB-Type for maximum flexibility with both tuning and dimming. D-Type for timing dimming functions (contact MEAN WELL for details).
Blank, B, and D versions are IP67. A and AB versions are IP65. A/AB types require internal use for Type HL applications.
