Frequently Asked Questions
Can I use the HLG-100H-48B to dim 48V LED outdoor area lights?
Yes. The HLG-100H-48B supports dimming via 1-10V, PWM, and resistance signals, and its IP67 waterproof rating makes it fully suitable for exposed outdoor area lighting. It delivers 48V at up to 2A (100W) with smooth brightness control for energy-saving dimming schedules.
Is the HLG-100H-48B suitable for dimmable 48V LED stairwell or emergency path lighting?
It works well for stairwell and pathway luminaires where dimming reduces energy use during unoccupied periods. The constant-current output within the 24-48V range ensures stable light output, and the IP67 rating handles damp stairwells or semi-outdoor corridors.
Can I run dimmable 48V LED canopy lights at a fuel station with the HLG-100H-48B?
Yes. The IP67 waterproof rating and -40°C to +80°C operating range handle the harsh conditions at fuel station canopies. The dimming input allows reducing brightness during overnight hours for energy savings. Total load must stay at or below 100W.
How long a run of 48V LED strip can the HLG-100H-48B power?
The HLG-100H-48B provides up to 100W at 48V. Divide 100W by the strip's rated wattage per meter to calculate maximum length. A strip rated at 4W/m would allow up to 25 meters (100W / 4W per meter = 25m). Always check your strip's rated power per meter and keep total load within 100W.
Can the HLG-100H-48B withstand outdoor installations exposed to coastal salt spray?
The IP67 rating and sealed aluminium housing provide strong protection against moisture and dust, including salt spray. However, prolonged exposure to salt air accelerates corrosion on any metal enclosure. Periodic inspection and protective mounting (e.g., inside a ventilated NEMA-rated box) is recommended for coastal installations.
What does the 'B' suffix mean on the HLG-100H-48B?
The 'B' suffix indicates the model includes a dimming function input (1-10V, PWM, or resistance) but does not have the built-in potentiometer for output adjustment found on the A and AB variants. It retains the IP67 waterproof rating of the base HLG-100H-48. All 48V variants share the same 100W, 48V, 2A core output.
