Frequently Asked Questions

Can I use the HLG-150H-48 to power 48V LED street lights?

Yes. The HLG-150H-48 delivers 150W at 48V with up to 3.2A in constant-current mode, suitable for 48V LED street light fixtures. Its IP67 waterproof rating and -40°C to +90°C operating range allow reliable operation in fully exposed outdoor pole-mounted installations.

Is the HLG-150H-48 a good fit for 48V LED high-bay industrial lighting?

Yes. With 150W at 48V output, it can drive 48V high-bay LED fixtures used in warehouses, factories, and distribution centers. The aluminium casing dissipates heat effectively in enclosed ceiling spaces, and the wide 90-305VAC input handles varying industrial power supplies.

Can the HLG-150H-48 power 48V LED modules in outdoor signage?

Yes. At 150W and 48V, it can drive 48V LED channel letters, cabinet signs, or light-box modules. The 48V output reduces current draw compared to lower-voltage alternatives, allowing longer wire runs with less voltage drop — a practical advantage for large sign installations.

How many meters of 48V LED strip can the HLG-150H-48 power?

Divide 150W by your strip's power consumption per meter. For example, a 48V strip rated at 10W/m could run up to 15 meters (150W / 10W per meter = 15m). Always check your strip's rated power per meter and keep total load at or below 150W.

Can the HLG-150H-48 be mounted outdoors without a separate enclosure?

Yes. Its IP67 waterproof rating means the unit is sealed against dust and can withstand temporary water immersion up to 1 meter. It can be mounted directly on outdoor walls, poles, or structures without needing an additional weatherproof enclosure, even in heavy rain or snow.

What are the differences between the HLG-150H-48, 48A, 48AB, and 48B models?

All four share the same 150W / 48V / 3.2A core specs. The base HLG-150H-48 has no output adjustment and is IP67 waterproof. The -48A adds output voltage/current adjustment via built-in potentiometer and is IP65. The -48AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -48B adds dimming input only and retains IP67.
