LED Drivers & Power Supplies

What's the difference between a constant-current and a constant-voltage LED driver?

Constant-current drivers deliver a fixed current — 350mA, 700mA, or 1050mA — for LED modules and fixtures rated in milliamps. Constant-voltage drivers hold a fixed 12V or 24V output for LED strip, tape, and multiple parallel loads. Match the driver type to the fixture's spec.

  • Constant current — fixed mA (350 / 700 / 1050mA) — for LED modules & fixtures rated in mA
  • Constant voltage — fixed 12V or 24V — for LED strip, tape & parallel loads

How do I size an LED driver to my fixture or strip?

Add the wattage of every connected LED, then choose a driver rated at or above that total, leaving about 20% headroom. For strip, multiply watts-per-foot by length. The driver's output voltage must match the load — 12V to 12V, 24V to 24V.

Which dimming type do I need — TRIAC, ELV, or 0-10V?

Match the driver's dimming to your control. TRIAC (forward-phase) and ELV (reverse-phase) drivers work with standard residential wall dimmers. 0-10V and DALI drivers pair with commercial low-voltage controls. A non-dimmable driver cannot be dimmed by any control.

  • TRIAC (forward-phase) — standard wall dimmer — residential
  • ELV (reverse-phase) — ELV wall dimmer — residential, electronic low-voltage
  • 0-10V — low-voltage 0-10V control — commercial
  • DALI — DALI controller — commercial / networked
  • Non-dimmable — on/off switch only — basic loads

Match driver dimming to the installed control — a mismatch causes flicker, drop-out, or no dimming.

What is a Class 2 LED driver?

A Class 2 driver limits its output to 60V and 100W or less (per NEC and UL 1310), so the low-voltage wiring needs no conduit. Most LED tape and many fixtures require a Class 2 driver. Class 2 is a safety rating, not a wattage class.

Can I use an LED driver outdoors?

Use a wet- or damp-rated driver with an IP65 to IP67 enclosure for outdoor, landscape, and sign applications. Indoor dry-location drivers must stay protected from moisture. Check the driver's IP rating and location listing against the install environment.
