Frequently Asked Questions
Can I use the HLG-120H-48B with a dimmer for outdoor 48V LED strip installations?
Yes. The HLG-120H-48B accepts 1-10V and PWM dimming signals and carries an IP67 waterproof rating, making it ideal for outdoor 48V LED strip runs where you also need brightness control. It can be mounted in exposed locations without a secondary enclosure.
Is the HLG-120H-48B suitable for dimmable 48V LED landscape or garden lighting?
Yes. At 120W and 48V with IP67 waterproof protection, it can power 48V landscape fixtures outdoors and be dimmed via a 1-10V signal for different scene settings. Its -40°C to +80°C operating range handles seasonal temperature extremes.
Can I pair with the HLG-120H-48B to a building management system for scheduled dimming?
Yes. The 1-10V/PWM dimming input is compatible with most building management or lighting control systems. This allows scheduled brightness changes, such as reducing sign or facade lighting intensity during late-night hours, while the IP67 rating permits outdoor placement.
How many meters of 48V LED strip can the HLG-120H-48B power?
The HLG-120H-48B supplies up to 120W at 48V. If your 48V strip draws 8W/m, you could run up to 15 meters (120W / 8W per meter = 15m). Always check your strip's rated power per meter and ensure the total load stays at or below 120W.
Can the HLG-120H-48B handle fully exposed outdoor conditions year-round?
Yes. Its IP67 rating means the unit is sealed against dust ingress and can withstand temporary submersion up to 1 meter. Combined with the -40°C to +80°C operating temperature range and aluminium casing, it is designed for permanent outdoor exposure in all seasons.
