Frequently Asked Questions
Can I use the HLG-240H-20AB to power dimmable 20V LED strips in a restaurant patio?
Yes. The HLG-240H-20AB delivers 240W at 20V with both output adjustment and a 1-10V/PWM dimming input, making it ideal for restaurant patios where you want to lower lighting levels during evening service. Its IP65 water-resistant rating is suitable for covered or semi-sheltered outdoor dining areas.
Is the HLG-240H-20AB appropriate for smart-home controlled 20V LED lighting?
Yes. The dimming input accepts 1-10V or PWM signals, which most smart lighting controllers and building management systems can provide. Combined with the output adjustment potentiometer, you can set a maximum brightness level and then use the smart controller to dim from there. The 240W capacity handles substantial LED loads.
Can the HLG-240H-20AB drive 20V LED cove lighting in a large retail space?
Yes. At 240W and 20V output, it can power extended runs of 20V LED cove lighting. The adjustable output lets you fine-tune the voltage to match the LED strip precisely, and the dimming input allows scene control or daylight-responsive dimming in the retail environment.
How many meters of 20V LED strip can the HLG-240H-20AB power?
Divide 240W by your strip's rated power per meter. For instance, a strip rated at 15W/m would allow 16 meters (240W / 15W per meter = 16m). Always check your strip's rated power per meter and keep the total load at or below 240W for reliable operation.
Can I mount the HLG-240H-20AB outdoors under a canopy or soffit?
Yes. The IP65 water-resistant rating protects against low-pressure water jets and dust, which is sufficient for sheltered outdoor installations such as canopies, soffits, and covered walkways. It is not rated for direct rain exposure or submersion. For fully exposed locations, consider the IP67-rated HLG-240H-20B.
