Meanwell HLG-240H-C1400B
The HLG-240H-C1400B is a high-power constant-current platform favored for large fixtures and multi-emitter arrays, offering strong efficiency, tight current regulation and ample thermal margin for aquarium applications. It sits between compact hobby drivers and full industrial units by delivering high output at a competitive price, making it more economical per watt than small drivers like the LCM-40DA while being less specialized (and often lower-cost) than some Inventronics high‑wattage offerings. For aquarists scaling up to high PAR requirements, the HLG-240H combines value and performance.
