24V Universal Dimmable LED Driver 45W - Smooth Full-Range Dimming

In this review the Armacost Lighting 45-Watt Universal Dimmable 24V DC LED Driver TRIAC 860450 is judged as a practical choice for hobbyists and professionals who need a reliable low-voltage power supply that dims cleanly. The bottom line: this driver is best for anyone installing LED strips, modules, puck lights or accent fixtures who wants consistent, flicker-free control from the lowest setting to full output. The review finds the unit especially valuable where compatibility with existing household dimmers and precise low-voltage dimmers is required.

Key Features

• Smooth full-range dimming: Provides stable, flicker-free dimming from 0 to 100% so LEDs do not pop on or drop off when used with compatible dimmers.
• Universal dimmer compatibility: Works with both 120V AC forward phase and reverse phase dimmers as well as low-voltage DC dimmers, reducing the need to change wall controls.
• No minimum load required: Dimming performs equally well when powering a single 3W puck or the full 45W of tape lighting, useful for mixed or growing installations.
• Plug-in or hardwire installation: Includes a detachable AC power cord for quick plug-in setup or the flexibility to hardwire for permanent installations.
• Professional electronics: Built with stable, energy-efficient components that maintain 24V output and consistent dimming behavior for LED accent lighting.
• Suitable for damp locations: Can be used in both dry and damp environments, expanding placement options for under-cabinet and decorative lighting.

Who It's For

This LED driver is aimed at DIYers, contractors and lighting installers who need a compact 24V, 45W power supply that will dim smoothly with common wall dimmers and low-voltage controls. It is ideal for retrofit strip lighting, under-cabinet illumination, display cases and mixed-load setups where a single driver must handle pucks and tape together.

Customers who require ultra-tight thermal constraints, extreme outdoor weatherproofing, or higher than 45W continuous output should consider other models. Likewise, those needing a very small form-factor internal driver for sealed fixtures might look elsewhere.

Pros & Cons

Pros

• Consistent, flicker-free dimming across the full range when paired with compatible dimmers.
• Flexible compatibility with both forward phase (triac) and reverse phase (ELV) AC dimmers and DC dimmers.
• No minimum load requirement, so it handles a single low-wattage light or the full rated capacity equally well.
• Includes detachable AC cord for easy plug-in or hardwire installation and professional-grade electronics for stable output.

Cons

• At 45W it may be underpowered for larger or more demanding installations that need higher wattage capacity.
• Some buyers note price sensitivity, so value depends on project scale and budget compared with simpler supplies.

Frequently Asked Questions

Will this driver dim with a Lutron wall dimmer?
Yes; it is compatible with both forward phase and reverse phase AC dimmers, and customers commonly report it works well with Lutron models.

Can I power a single 3W puck and still dim properly?
Yes; there is no minimum load, so dimming works equally well for a single low-wattage fixture or up to the 45W maximum.

Is the power cord included and can it be hardwired?
Yes; a detachable AC power cord is included and the unit can be hardwired if a permanent installation is preferred.
