100W Dimmable LED Driver Transformer 24V DC - Smooth Flicker-Free

In this review of the 100W Dimmable LED Driver Transformer, the bottom line is simple: this unit is for DIYers and installers who need a reliable 24V DC power supply that dims smoothly with widely used wall dimmers. It converts 100-277V AC down to 24V DC at up to 4.17A and is built with multiple safety protections, so the reviewer recommends it when under-cabinet ribbon lighting or LED module projects require steady, quiet operation and compatibility with brands like Lutron and Leviton.

Key Features

• Wide input range: Accepts 100-277V AC so it can be used in a variety of residential and commercial mains environments without a separate transformer.
• Stable 24V output: Provides 24V DC at up to 4.17A (100W) to power LED strips and modules with consistent voltage under load.
• Smooth dimming: Works with forward/reverse phase, TRIAC, MLV, and ELV dimmers to deliver flicker-free dimming from 0 to 100% when paired with compatible dimmer switches.
• Safety protections: Built-in short circuit, overload, and over temperature protection help prevent damage to fixtures and reduce troubleshooting time.
• Certifications and support: UL and cUL listings, Class P/Type HL, and FCC certification plus a 6-year back-up promise provide long-term confidence for installations.

Who It's For

This driver is aimed at homeowners, cabinet makers, and lighting installers who fit low-voltage LED strips or modules and want a compact, obscured power supply that supports popular wall dimmers from makers such as Lutron and Leviton. It is especially useful for under-cabinet lighting, display cases, and retrofit projects where smooth dimming and quiet operation matter.

Those who should look elsewhere include users who need integrated control protocol features (DMX, 0-10V) or multi-channel RGB drivers, since this is a single-output 24V DC power supply designed for general dimming rather than addressable lighting control.

Pros & Cons

Pros

• Reliable compatibility with common wall dimmers delivers smooth dimming and minimal flicker for LED ribbons.
• Robust safety features reduce risk during installation and operation.
• Wide 100-277V input and high power factor make it efficient for varied installations.
• Quiet, compact design that installers report can be hidden easily in cabinets.

Cons

• Size receives mixed feedback, so installers in very tight enclosures should measure before fitting.
• Not suitable for projects needing multi-channel or digital control such as RGB addressable strips.

Our Verdict

The HitLights 100W dimmable driver is a solid choice for anyone installing low-voltage LED strips who needs dependable 24V power and smooth compatibility with mainstream dimmers. Its safety protections, certifications, and quiet performance make it a good value for under-cabinet and retrofit lighting projects; measure first if space is at a premium, but otherwise it delivers steady, flicker-free dimming over a wide input range.

Frequently Asked Questions

Will this driver work with Lutron and Leviton dimmers?
Yes. It is compatible with forward/reverse phase, TRIAC, MLV, and ELV dimmers from those manufacturers when those dimmers are rated for LED loads.

Can I use this for RGB LED strips?
No. This is a single-output 24V DC driver intended for monochrome LED strips or modules, not multi-channel RGB or addressable strips.

What protections does it include?
The unit includes short circuit, overload, and over temperature protections to protect the driver and connected fixtures.
