Frequently Asked Questions
Can I use the HLG-240H-C1750B for a dimmable commercial LED downlight installation?
Yes. The HLG-240H-C1750B delivers 1750mA constant current across a 71-143V range, up to 250.25W. The B suffix provides a 1-10V/PWM dimming input, making it compatible with commercial dimming systems and building management controllers. It can drive high-power downlight modules in series as long as total forward voltage stays within 71-143V.
Is the HLG-240H-C1750B a good fit for dimmable LED flood lights on a building facade?
Yes, provided the flood light's LED array requires approximately 1750mA and has a forward voltage within 71-143V. The IP65 rating handles sheltered outdoor locations well, and the dimming input allows scene control for architectural lighting effects. For fully exposed installations, ensure the driver is housed in a weatherproof enclosure.
Can the HLG-240H-C1750B power a high-output LED panel light with dimming?
Yes. At 1750mA and up to 250.25W, it can drive large LED panel lights or troffers. The B variant's 1-10V/PWM dimming input integrates with standard commercial dimming controls. Note this variant does not include an output adjustment potentiometer, so the drive current is fixed at 1750mA before dimming attenuation.
How many LEDs can I run in series with the HLG-240H-C1750B?
The number depends on each LED's forward voltage at 1750mA. The CC voltage range is 71-143V, so you need enough LEDs in series to total at least 71V and no more than 143V. For instance, with LEDs that each drop about 35V at 1750mA, you could run 2 to 4 in series (70-140V). Always verify forward voltages from your LED datasheet.
Can the HLG-240H-C1750B be used inside a sealed outdoor luminaire enclosure?
Yes. The IP65-rated aluminium casing protects against dust and water jets. When mounted inside a sealed luminaire, ensure adequate ventilation or thermal management since the driver generates heat up to its 250.25W capacity. The operating range of -40°C to +90°C provides generous headroom for enclosed installations.
