Frequently Asked Questions
Can I use the HLG-100H-42B to dim 42V LED landscape lighting outdoors?
Yes. The HLG-100H-42B supports dimming via 1-10V, PWM, and resistance signals, and its IP67 waterproof rating makes it suitable for fully exposed outdoor landscape lighting installations. It delivers 42V at up to 2.28A (100W) with smooth brightness control.
Is the HLG-100H-42B suitable for dimmable 42V LED parking lot fixtures?
It is a strong choice for parking lot luminaires that need dimming for energy savings during low-traffic hours. The IP67 rating handles direct rain, dust, and temperature swings from -40°C to +80°C. Total fixture load must not exceed 100W at 42V.
Can I run 42V dimmable LED tunnel or underpass lights with the HLG-100H-42B?
Yes, provided the total load is within 100W. The IP67 waterproof enclosure handles the damp, dusty conditions typical of tunnels and underpasses. The dimming input allows daylight-responsive brightness control when paired with an appropriate controller.
How long a run of 42V LED strip can the HLG-100H-42B power?
The HLG-100H-42B supplies up to 100W at 42V. Divide 100W by your strip's wattage per meter to find the maximum run length. For a strip rated at 7W/m, that would be approximately 14.2 meters (100W / 7W per meter). Always verify your strip's rated power per meter and keep total load at or below 100W.
Can the HLG-100H-42B be installed in locations subject to temporary flooding or submersion?
The IP67 rating certifies protection against temporary immersion in water up to 1 meter. Combined with its sealed aluminium housing, the HLG-100H-42B can tolerate brief flooding events. For permanent underwater use, a higher IP rating would be needed.
What does the 'B' suffix mean on the HLG-100H-42B?
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 model. All 42V variants share the same 100W, 42V, 2.28A core output.
