Frequently Asked Questions
Can I use the HLG-120H-30B with a 1-10V dimmer for outdoor 30V LED lighting?
Yes. The HLG-120H-30B accepts 1-10V and PWM dimming signals and carries an IP67 waterproof rating. You can dim outdoor 30V LED fixtures via an external controller while the driver is mounted in a fully exposed location. It delivers up to 120W at 30V.
Is the HLG-120H-30B a good choice for dimmable 30V LED facade or building wash lighting?
Yes. The 120W output at 30V can power a long run of facade wash fixtures or wall grazers. The dimming input enables scheduled brightness profiles or dynamic lighting scenes for architectural effect, and the IP67 rating allows outdoor mounting close to the fixtures.
Can the HLG-120H-30B power dimmable 30V LED fixtures in a car park or outdoor area?
Yes. With 120W at 30V, IP67 waterproof protection, and a -40°C to +80°C operating range, it is built for fully exposed outdoor installations. The dimming input lets you reduce brightness during low-traffic hours for energy savings.
How many meters of 30V LED strip can the HLG-120H-30B handle?
The HLG-120H-30B provides up to 120W at 30V. For a strip rated at 8W/m, you could run up to 15 meters (120W / 8W per meter = 15m). For a strip at 18W/m, the limit is about 6.6 meters. Check your strip's rated power per meter and keep total load at or below 120W.
Can the HLG-120H-30B handle direct rain, freezing temperatures, and summer heat?
Yes. The IP67 waterproof rating protects against temporary submersion up to 1 meter, and the operating temperature range of -40°C to +80°C covers extreme cold and hot climates. It can be mounted fully exposed without an additional enclosure.
