Frequently Asked Questions

Can I use the HLG-150H-20 to power 20V LED strip lighting outdoors?

Yes. The HLG-150H-20 outputs 20V at up to 7.5A (150W) and carries an IP67 waterproof rating, so it can be installed in fully exposed outdoor locations including rain, snow, and high-humidity environments. Its aluminium casing and -40°C to +90°C operating range handle extreme weather conditions.

Is the HLG-150H-20 a good choice for powering 20V LED channel letter signs?

Yes. With 150W at 20V, the HLG-150H-20 can drive a substantial run of 20V LED sign modules. The IP67 waterproof rating makes it suitable for outdoor signage installations, and the wide 90-305VAC input accommodates varying mains voltages found in commercial signage deployments.

Can the HLG-150H-20 power 20V LED panel lights in a warehouse or industrial space?

Yes, as long as the panels operate at 20V and their combined wattage stays within 150W. The constant-current mode with a CC voltage range of 10-20V accommodates panels that may draw slightly less than 20V during startup. The robust aluminium housing suits industrial environments.

How many meters of 20V LED strip can the HLG-150H-20 power?

Divide 150W by your strip's rated power per meter. For example, a strip rated at 10W/m allows up to 15 meters (150W / 10W per meter = 15m). A strip rated at 14W/m allows about 10.7 meters. Always check your strip's rated power per meter and keep total load at or below 150W.

Can the HLG-150H-20 handle full rain exposure or temporary flooding?

Yes. Its IP67 rating means the enclosure is dust-tight and protected against temporary immersion in water up to 1 meter. It can be mounted outdoors without any additional weatherproof enclosure, even in locations subject to heavy rain or occasional standing water.

What are the differences between the HLG-150H-20, 20A, 20AB, and 20B models?

All four share the same 150W / 20V / 7.5A core specs. The base HLG-150H-20 has fixed output and IP67 waterproof rating. The -20A adds output voltage/current adjustment via built-in potentiometer (IP65). The -20AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -20B adds dimming input only and retains IP67.
