Frequently Asked Questions
Can I use the HLG-40H-48B to power a small run of 48V LED strip lighting outdoors?
Yes. The HLG-40H-48B outputs 48V at up to 0.84A (40W) and has an IP67 waterproof rating, so it can be mounted in fully exposed outdoor locations subject to rain, snow, or temporary standing water. Its wide 90-305VAC input handles varying mains voltages worldwide.
Can I use the HLG-40H-48B with a 1-10V dimmer for accent lighting?
Yes. The B suffix indicates it accepts external dimming signals via 1-10V, PWM, or resistance input. This makes it suitable for accent or architectural lighting where you want remote brightness control without a built-in potentiometer for voltage adjustment.
Is the HLG-40H-48B appropriate for 48V LED under-cabinet lighting in a commercial kitchen?
Yes. Its IP67 rating protects against water jets and temporary submersion, which is more than sufficient for kitchen splash zones. At 40W and 48V, it can drive a modest run of under-cabinet 48V LED strips, and the dimming input allows brightness control via an external signal.
How many meters of 48V LED strip can the HLG-40H-48B handle?
That depends on the strip's rated power per meter. The HLG-40H-48B supplies up to 40W at 48V. For a strip drawing 10W/m, you could power up to 4 meters (40W / 10W per meter = 4m). Always check your strip's rated power per meter and stay at or below 40W total.
Can the HLG-40H-48B be installed in an outdoor landscape lighting junction box?
Yes. Its IP67 waterproof rating means it can handle direct rain, dust, and even brief submersion up to 1 meter. It is well suited for burial-grade enclosures or surface-mounted outdoor junction boxes used in landscape lighting installations.
