Frequently Asked Questions
Can I use the HLG-320H-24B to dim outdoor 24V LED landscape lighting?
Yes. The HLG-320H-24B supports 1-10V and PWM dimming and carries an IP67 waterproof rating. This combination makes it ideal for outdoor 24V landscape lighting where you want to dim pathways or garden lights at night while the driver sits exposed to rain and sprinklers.
Is the HLG-320H-24B suitable for dimmable 24V LED parking lot or security lighting?
Yes. At 320W and 24V with dimming capability, it can power large arrays of 24V LED parking lot or security fixtures. Connecting a photocell or timer to the dimming input allows automatic brightness reduction during low-traffic hours to save energy.
Can the HLG-320H-24B drive 24V LED signage with nighttime dimming?
Yes. With 320W at 24V, it handles substantial 24V sign loads. The 1-10V/PWM dimming input lets you reduce sign brightness at night to comply with local light-pollution ordinances or to conserve power without fully switching off the sign.
How many meters of 24V LED strip can the HLG-320H-24B power?
Divide 320W by your strip's wattage per meter. A strip rated at 12W/m, for example, allows about 26.6 meters (320W / 12W per meter). Always check your strip's rated power per meter and keep total load at or below 320W.
Can the HLG-320H-24B withstand direct rain and snow exposure in an outdoor installation?
Yes. Its IP67 waterproof rating protects against temporary submersion up to 1 meter, so direct rain, snow, ice, and hose cleaning pose no risk. It can be mounted outdoors without any additional weatherproof enclosure.
Does the HLG-320H-24B work in extremely cold climates?
Yes. The operating temperature range is -40°C to +90°C, so the driver will start and operate reliably in sub-zero conditions found in northern climates. The aluminium casing also aids heat dissipation in warmer environments.
