Frequently Asked Questions
Can I use the HLG-240H-54 to power 54V LED high-bay fixtures in a warehouse?
Yes. The HLG-240H-54 delivers 240W at 54V with up to 4.45A in constant-current mode. It is well suited for 54V high-bay LED fixtures commonly used in warehouses, manufacturing floors, and distribution centers. The IP67 waterproof rating allows mounting in locations exposed to dust and moisture.
Is the HLG-240H-54 a good fit for driving 54V LED panel lights in a commercial ceiling grid?
Yes. At 240W and 54V, the HLG-240H-54 can power multiple 54V LED panels in a commercial ceiling installation. Its constant-current output with a CC range of 27-54V accommodates LED panels that have varying forward voltages during startup and thermal stabilization.
Can the HLG-240H-54 drive series-connected 54V LED COB modules for grow lights?
Yes, provided the total load stays at or below 240W. The HLG-240H-54 outputs up to 4.45A at 54V in constant-current mode, making it compatible with 54V COB LED boards used in horticultural lighting. The wide input range of 90-305VAC supports international mains voltages.
How many watts of 54V LED load can the HLG-240H-54 support?
The HLG-240H-54 supplies up to 240W at 54V (4.45A). For example, if each 54V LED module draws 60W, you could connect up to four modules (4 × 60W = 240W). Always verify each module's rated power consumption and keep the total at or below 240W.
Can the HLG-240H-54 be installed outdoors in direct rain or harsh weather?
Yes. Its IP67 waterproof rating provides full protection against dust ingress and temporary water immersion up to 1 meter. You can mount it in exposed outdoor locations, wet-rated junction boxes, or directly on rooftops without additional weatherproofing.
What distinguishes the HLG-240H-54 from the 54A, 54AB, and 54B models?
All four share 240W / 54V / 4.45A core specs. The base HLG-240H-54 has fixed output and IP67 waterproof rating. The -54A adds output voltage/current adjustment via potentiometer (IP65). The -54AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -54B provides dimming input only and retains IP67 waterproof rating.
