FAQ

Can I use the HLG-150H-20AB for dimmable 20V LED strip lighting?

Yes. The HLG-150H-20AB delivers 150W at 20V and accepts a 1-10V or PWM dimming signal, allowing smooth brightness control for 20V LED strips. It also has a built-in potentiometer for setting the maximum output level, giving you two layers of brightness management.

Is the HLG-150H-20AB a good fit for dimmable retail display or showcase lighting?

Yes. The combination of 150W at 20V, adjustable output via potentiometer, and external dimming input makes it well-suited for retail environments where lighting scenes need to change throughout the day. The wide 90-305VAC input supports international retail locations.

Can the HLG-150H-20AB be used with a building automation system to dim 20V LED fixtures?

Yes, if the system provides a suitable output. The dimming input accepts 1-10VDC, 10V PWM (100Hz-3KHz) or resistance signals between DIM+ and DIM-, so building automation and lighting control systems with one of these outputs can drive it. MEAN WELL recommends connecting the LEDs directly to the driver when dimming.

Can the HLG-150H-20AB power a dimmable 20V LED signage installation?

Yes. At 150W and 20V output, it can drive 20V sign modules while the dimming input allows timed brightness reduction for nighttime operation or energy savings. The built-in potentiometer lets you set the peak output to match your module string precisely.

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

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

Is the HLG-150H-20AB rated for outdoor use?

It carries an IP65 water-resistant rating, which protects against dust and low-pressure water jets. This makes it suitable for sheltered outdoor locations such as covered walkways, soffits, and canopies. For fully exposed rain or submersion scenarios, the IP67-rated HLG-150H-20B with dimming would be a better match.
