| Problem | Likely Cause | Fix | |---------|--------------|-----| | No light | Loose AC or DC connection | Check terminal screws, LED polarity | | Flickering | Wrong dimmer type | Use 0-10V dimmer only | | Flickering (no dimmer) | LED load too low for driver | Add more LEDs or replace with lower current driver | | Overheating / shutdown | Poor ventilation | Move to open air or reduce load | | Humming noise | Loose transformer laminations (rare) | Replace driver – safe but annoying | | Lights don’t turn off fully | 0V dimming gives 5% min | Use AC cutoff relay or driver with "0-10V off" feature |
The LP46 Lite driver is a workhorse for constant-current LED systems. It doesn’t try to do everything—but what it does, it does dependably. Respect its constant-current nature, use a proper 0-10V dimmer, and keep it cool, and it will serve for years. lp 46 lite driver
: Modern macOS versions often use AirPrint , allowing you to add the printer via System Settings > Printers & Scanners without a separate manual driver installation. | Problem | Likely Cause | Fix |
💡 If lights flicker at low dim levels, add a 0-10V pull-up resistor (10kΩ) or check dimmer compatibility. : Modern macOS versions often use AirPrint ,
