ELEGRP Digital Dimmer Light Switch for 300W Dimmable LED/CFL Lights and 600W Incandescent/Halogen, Single Pole/3-Way LED Slide Dimmer, Wall Plate Included, UL Listed, 6 Pack, Matte White

What I tested

I swapped several legacy dimmers and toggles in my house with the ELEGRP DM19—an affordable, no‑neutral, digital slide dimmer that comes in a six‑pack. I ran it in a few scenarios:

• Single‑pole circuits with multiple recessed LED wafers (den and kitchen)
• A 3‑way staircase circuit mixing a PAR38 can and a thin LED disk
• An under‑cabinet LED setup that was uncomfortably bright at full power
• A dining fixture with a large LED chandelier

Across those spaces I put the dimmer through daily use for a few weeks, tweaking the low‑end trim, turning the locator light on and off, and checking for flicker, buzz, and nuisance glow.

Installation and setup

Installation is straightforward, especially for older homes. The big win is that it doesn’t require a neutral wire. The DM19 uses standard screw terminals (line, load, traveler, and ground), and the body is slim enough to fit crowded boxes. ELEGRP includes a clean, screwless wall plate in matte white that helps the finished install look more “built‑in” than budget.

For multi‑way setups (3‑ or 4‑way), you only use one DM19 on the circuit; the companion switch(es) remain standard mechanicals. In my stair circuit, wiring was conventional: the dimmer replaced one of the 3‑way switches, and the other stayed as‑is. Brightness memory worked correctly—the light turned on to the level set at the dimmer, regardless of which switch I last used.

Two setup details that matter:

• Low‑end trim: Pull the face cover and you’ll find a small adjustment to set the minimum brightness. This is essential with LEDs. I set it so the lights dim as low as possible without dropout.
• Locator light: A tiny white indicator can be enabled to glow when the light is off. It’s useful in hallways, but I disabled it in bedrooms to avoid any night‑time glow.

From power off to finish, each swap took me 10–20 minutes, including trim and locator light tuning.

Controls and everyday ergonomics

The control scheme is simple: a vertical slider for level, plus an on/off switch action that respects the last brightness you set. The slider feels smooth but firm, not loose or scratchy. The digital fade‑on is subtle—on most loads, the light ramps up in about a second. I noticed an intentional soft start even at higher slider positions, which looks refined and likely reduces inrush stress on both bulbs and the dimmer.

Brightness memory is solid. Turn the light off at 25%, come back later, and it returns to 25%. The locator light, when enabled, is unobtrusive and well‑diffused.

Performance with different loads

On higher‑quality, dimmable LEDs, performance is impressively smooth for a budget unit. With six 6‑inch LED wafers in my den, I was able to dim to a “nightlight” level—with no visible stepping, no audible buzz, and no flicker after I set the low‑end trim. In the kitchen’s under‑cabinet LEDs (with a decent driver), the DM19 reached near‑zero output while staying stable.

The staircase 3‑way, with mismatched LED types (one PAR38 retrofit, one disk), was a bigger test. Without adjustment, the disk would drop out sooner than the PAR38. After lowering the minimum and balancing for the more finicky lamp, both stayed on together and dimmed uniformly. The ramp feels truly electronic; you can see a smooth, linear‑ish response rather than the “jumpiness” some analog dimmers show on LEDs.

A couple of watch‑outs:

• Minimum load matters. On a very small LED load (sub‑10W), I saw shimmer near the bottom of the range. Raising the low‑end trim eliminated it. Adding another LED or using a dimmer bypass would also help.
• Very low settings can add delay. With the slider set at the absolute minimum, some fixtures took 1–2 seconds to light on turn‑on. That’s the digital soft start and driver behavior interacting. In practice, nudging the minimum slightly higher avoids the pause without giving up much low‑level range.

I didn’t detect meaningful EMI‑related flicker when large appliances kicked on, but I did have one fixture that “ghosted” faintly when off. Disabling the locator light cured it. On stubborn circuits without a neutral, installing a small LED load adapter (bypass) is a reliable fix for residual glow.

Noise, heat, and build quality

Mechanically, the dimmer feels better than its price suggests. The slider and faceplate are snug, the matte finish hides fingerprints, and the included plate sits flush. The unit runs cool in normal duty; after an hour at 60–70% with a ~60W LED load, the face was warm but far from hot.

Audible noise was minimal in my tests. With my ear close to the faceplate, I could barely hear a faint electronic whisper on one transformer‑based fixture; on standard LED lamps and wafers, it was effectively silent. If you’re driving magnetic low‑voltage transformers, results can vary—check your driver compatibility and be ready to adjust the low end.

Compatibility realities

ELEGRP rates this unit for up to 300W of dimmable LED/CFL and 600W incandescent/halogen. Those numbers are generous for residential use, but LED compatibility still depends on lamp drivers. Practical tips:

• Use dimmable LEDs from reputable brands and try to keep a circuit’s lamps uniform.
• After install, set the low‑end trim per circuit. It takes a minute and pays off in stability.
• If you see faint glow when “off,” disable the locator light or add a dimmer bypass.
• Extremely small loads can misbehave at the bottom of the range; either raise the low limit or increase load slightly.

I also tried an LED chandelier with a mix of small base bulbs. The DM19 dimmed it smoothly to roughly 10–15% before the bulbs began to drop. Swapping to bulbs with better dimming drivers extended the low range to ~5%. The dimmer wasn’t the limiting factor—the bulbs were.

Safety, listings, and warranty

The dimmer is UL/CUL listed, which is table stakes but still important for insurance and inspection. The two‑year warranty is respectable, and the inclusion of a screwless wall plate per unit adds real value for finish quality.

Value and competition

As a six‑pack, the per‑unit cost is very compelling compared to name‑brand competitors. You’re not getting advanced features like custom dimming curves, multi‑scene presets, or smart connectivity. But you are getting:

• No‑neutral convenience for older wiring
• Clean industrial design with included plates
• Smooth digital fade and reliable memory
• Practical adjustability for LEDs and an optional locator

In side‑by‑side feel and performance, the DM19 holds its own for most residential LED applications, especially where cost and volume matter—kitchens, dens, hallways, and bedrooms.

What could be better

• Clearer guidance on minimum load expectations would help users avoid shimmer on tiny LED circuits.
• The soft‑start delay at the lowest setting can feel slow in some fixtures; a user‑adjustable fade time would be a nice future feature.
• Mixed‑technology circuits (e.g., different LED models on one run) require more patience to tune; that’s typical of LED dimming, but worth noting.

Who it’s for

• Homeowners upgrading multiple rooms to dimmable LEDs without pulling neutrals
• Remodelers who want a consistent look and dependable function on a budget
• Anyone who values smooth, quiet dimming with a simple, tactile control

If you need app control, voice assistants, or granular curve shaping, this isn’t that product. If you want dependable, flicker‑free dimming across everyday LED loads at a very reasonable price, it fits well.

Recommendation

I recommend the ELEGRP DM19. It installs quickly without a neutral, dims modern LEDs smoothly once you set the low‑end trim, and includes touches—like a screwless plate and optional locator light—that make living with it pleasant. In my testing it stayed quiet, played nicely in 3‑way circuits, and handled mixed LED fixtures better than many budget dimmers.

Be mindful of a few caveats: keep loads above a minimal threshold, match your lamps when possible, and disable the locator light (or add a bypass) if you see ghosting. With those basics in place, the DM19 delivers reliable, attractive dimming at a price that’s hard to argue with.
