Frequently Asked Questions
Can I use the XLG-20-L-B to drive LED downlights in a residential retrofit project?
Yes. The XLG-20-L-B delivers 18.9W at 350mA with a constant current output range of 32–54V, which suits mid-string LED downlight modules designed for that voltage range. Its IP67 rating also allows installation in damp locations such as bathroom ceiling cavities.
Is the XLG-20-L-B suitable for outdoor LED signage modules?
Yes. The IP67 waterproof rating makes it appropriate for outdoor signage enclosures where moisture ingress is a concern. At 18.9W and 350mA constant current, it can drive low-wattage signage LED arrays whose combined forward voltage falls within the 32–54V CC output range.
Can I use this driver with a small LED array for architectural accent lighting?
Yes, provided the LED array's total forward voltage falls between 32V and 54V and the LEDs are rated for 350mA constant current drive. The number of LEDs in the string depends on each LED's individual forward voltage. The metal case and –40°C to +80°C operating range make it suitable for recessed architectural fixtures.
Does the XLG-20-L-B support dimming?
Yes. The '-B' suffix indicates 3-in-1 dimming support, meaning it accepts PWM, resistance, and 1–10V analog dim signals. This allows integration with standard lighting control systems without additional conversion hardware.
Can the XLG-20-L-B operate in cold outdoor environments?
Yes. The driver is rated for operation from –40°C to +80°C and carries an IP67 waterproof rating, making it suitable for unheated outdoor enclosures in cold climates. The wide input range of 90–305VAC also accommodates international mains voltages.
How does the XLG-20-L-B differ from the XLG-20-H-B and XLG-20-M-B?
All three are 3-in-1 dimmable, IP67-rated drivers in the same 20W-class. The XLG-20-H-B outputs 700mA into a 40V range; the XLG-20-M-B outputs 500mA into a 50V range; the XLG-20-L-B outputs 350mA into a 60V range at 18.9W. Choose the variant whose voltage and current rating matches your LED string's specifications.
How many LEDs can the XLG-20-L-B drive in series?
The driver operates in constant current mode with a 32–54V output range. The number of LEDs in series depends on each LED's forward voltage — there is no fixed count. Ensure the total series forward voltage of your string falls within 32–54V at 350mA.
