Frequently Asked Questions
Can I use the HLG-120H-12B to dim 12V LED landscape path lighting outdoors?
Yes. The HLG-120H-12B supports dimming via 1-10V, PWM, and resistance signals, and its IP67 waterproof rating makes it ideal for fully exposed outdoor landscape lighting. You can dim 12V LED path lights for energy savings at night while the driver handles up to 120W.
Is the HLG-120H-12B a good choice for dimmable 12V LED strip lighting on building facades?
It is well suited for facade lighting applications requiring dimming control. The 120W output at 12V provides 10A of current for driving long runs of 12V LED strip, and the IP67 waterproof rating allows direct exposure to weather without additional enclosures.
Can I power dimmable 12V LED fountain or water feature lighting with the HLG-120H-12B?
The HLG-120H-12B is IP67 rated, which means it can withstand temporary submersion and is well suited for installation near water features. It delivers 12V at up to 10A (120W) with dimming control. However, the driver itself should not be permanently submerged; mount it in a nearby junction box accessible for maintenance.
How many meters of 12V LED strip can the HLG-120H-12B handle?
The HLG-120H-12B provides up to 120W at 12V. Divide 120W by your strip's rated wattage per meter to find the maximum run. For instance, a 12V strip at 14.4W/m allows approximately 8.3 meters (120W / 14.4W per meter). Always check your strip's rated power per meter and keep total load within 120W.
Can the HLG-120H-12B operate reliably in extreme cold or heat?
Yes. The HLG-120H-12B is rated for -40°C to +80°C operating temperatures, covering extreme cold-climate installations as well as hot enclosed spaces. The IP67 sealed aluminium housing protects the electronics from condensation and thermal cycling in harsh environments.
What does the 'B' suffix mean on the HLG-120H-12B versus the base HLG-120H-12?
The 'B' suffix indicates the model includes a dimming function input supporting 1-10V, PWM, and resistance dimming signals, while retaining the same IP67 waterproof rating as the base model. The base HLG-120H-12 has fixed output with no dimming. Both deliver 120W at 12V and 10A.
