Frequently Asked Questions
Can I use the XLC-40-12 to power 12V LED strips in a commercial display case or shop fitting?
Yes, the XLC-40-12 outputs 40.8W at 12V, giving it more headroom than the 25W models for longer LED strip runs in commercial display cases or shop fittings. The built-in-use form factor fits inside standard luminaire bodies and the compact 147.0 × 32.0 × 40.0 mm case allows installation in tight spaces.
Is the XLC-40-12 suitable for powering 12V LED strip in a retail signage lightbox?
Yes, the XLC-40-12 is well suited to 12V LED lightbox applications, with 40.8W available to support moderate-area backlit signs. The flicker-free output is important for photographic or video recording environments where lightbox flicker would be visible on camera. The wide 100–305VAC input ensures compatibility with mains supplies worldwide.
Can the XLC-40-12 drive 12V LED strips in a hospitality or restaurant mood lighting installation?
Yes, the XLC-40-12 delivers 40.8W at 12V constant voltage, appropriate for hospitality cove or mood lighting that uses 12V LED strip. The flicker-free characteristic is important in dining environments where flicker can cause discomfort to occupants. For dimming, check whether the control method is compatible with this constant voltage driver.
How much 12V LED strip can the XLC-40-12 power?
The XLC-40-12 provides up to 40.8W at 12V and 3.4A. Divide 40.8W by your strip's rated watts per meter — for a 14.4 W/m strip that is approximately 2.83 m (40.8 ÷ 14.4 ≈ 2.83 m), and for a 9.6 W/m strip about 4.25 m. Always verify your strip's rated power per meter and limit continuous loads to around 80% of driver output for long-term reliability.
What is the operating temperature range of the XLC-40-12, and can it be mounted in a tight ceiling void?
The XLC-40-12 is rated from -25°C to +90°C. Ceiling voids can reach elevated ambient temperatures, so the broad upper limit provides useful headroom. Consult the full datasheet for output derating curves at elevated temperatures to ensure the 40.8W rating is maintained at the ambient temperature in your specific installation.
What is the difference between the XLC-25-12 and the XLC-40-12?
The XLC-25-12 delivers 25.2W at 12V and 2.1A, while the XLC-40-12 delivers 40.8W at 12V and 3.4A — approximately 62% more power. Both share the same 147.0 × 32.0 × 40.0 mm case dimensions, input range of 100–305VAC, and -25°C to +90°C operating temperature. The XLC-40-12 is suitable for longer LED strip runs or higher-wattage loads where the 25.2W model would be insufficient.
