Frequently Asked Questions

Can I use the HLG-240H-54B for outdoor 54V LED landscape path lighting with dimming?

Yes. The HLG-240H-54B delivers 240W at 54V with an IP67 waterproof rating and a built-in 1-10V/PWM dimming interface. It can be installed in exposed outdoor landscape fixtures and dimmed via a landscape lighting controller for curfew or dawn-to-dusk operation.

Is the HLG-240H-54B suitable for dimming 54V LED streetlights from a smart city controller?

Yes. The B suffix provides a 1-10V/PWM dimming input that accepts signals from smart lighting controllers. At 240W and 54V with IP67 protection, the HLG-240H-54B can be mounted in exposed streetlight housings and dimmed based on traffic flow, time schedules, or ambient light sensors.

Can the HLG-240H-54B power dimmable 54V LED flood fixtures in a sports field?

Yes, provided the total load does not exceed 240W. The HLG-240H-54B outputs up to 4.45A at 54V and the dimming input allows reducing brightness during practice sessions versus game-day operation. The IP67 enclosure withstands direct rain, field irrigation spray, and temperature extremes from -40°C to +90°C.

How many watts of 54V LED fixtures can I connect to the HLG-240H-54B?

The HLG-240H-54B delivers up to 240W at 54V (4.45A). Your total connected load must stay at or below 240W. For example, six 54V fixtures at 38W each total 228W, which is within capacity. Always verify each fixture's rated wattage before connecting.

Can the HLG-240H-54B be mounted in a location subject to temporary water immersion?

Yes. The IP67 rating provides full dust protection and allows temporary immersion in water up to 1 meter for 30 minutes. This makes it suitable for ground-level junction boxes, flood-prone locations, or areas near water features where occasional submersion may occur.
