Frequently Asked Questions
Can I use the HLG-185H-42B for dimmable 42V outdoor LED security lighting?
Yes. The HLG-185H-42B delivers 185W at 42V with 1-10V/PWM dimming input and an IP67 waterproof rating. It can power and dim outdoor security floods, perimeter lights, or motion-triggered 42V LED fixtures while being fully exposed to rain, dust, and temperatures from -40°C to +90°C.
Is the HLG-185H-42B suitable for dimmable 42V LED street or parking lot lighting?
Yes. At 185W and 42V with constant-current operation across a 21-42V CC range, it reliably drives LED street lights or parking lot fixtures. The 1-10V/PWM dimming input enables midnight dimming or time-based brightness scheduling, and the IP67 rating handles all outdoor weather conditions.
Can the HLG-185H-42B power 42V LED tunnel or underpass lighting with automated dimming?
Yes. The 1-10V/PWM dimming input pairs with photocell or automation controllers to adjust brightness based on ambient light levels in tunnels or underpasses. The IP67 waterproof rating handles the high moisture and dust typical of these environments, and 185W at 42V provides substantial drive capacity.
Can I use the HLG-185H-42B for dimmable 42V LED fixtures on a building exterior?
Yes. With IP67 waterproof protection and 1-10V/PWM dimming, it is well suited for exterior wall washers, facade lighting, or soffit-mounted 42V LED fixtures where brightness needs to change based on time of day. The aluminium casing and -40°C to +90°C range ensure long-term outdoor durability.
How many meters of 42V LED strip can the HLG-185H-42B support?
Divide 185W by your strip's wattage per meter. For example, a 42V strip rated at 14W/m would allow about 13.2 meters (185W / 14W per meter = 13.2m). Always check your strip's rated power per meter and keep total load at or below 185W.
Can the HLG-185H-42B withstand coastal or high-humidity outdoor environments?
Yes. The IP67 waterproof rating provides full dust protection and temporary submersion resistance, while the aluminium casing and -40°C to +90°C operating range handle salt air, humidity, and temperature extremes. For long-term coastal installations, periodic inspection of cable entry points is still advisable.
