You want to dim a bedside lamp from your phone and have it come back on after a power blink. That is the whole job of a Z-Wave lamp module, and the three plug-in dimmers below all do it, each with a different strength. One is the reliable indoor workhorse, one is sealed for outdoor use, and one leaves your second wall socket free while carrying the highest wattage.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Every module here speaks Z-Wave, so it needs a hub rather than your Wi-Fi router — that is the single fact that trips up most first-time buyers. Here is how to pick the z-wave lamp module that matches your lamps, your hub, and your outlet space.
Top Picks
How To Choose The Best Z-Wave Lamp Module
A Z-Wave lamp module is a small plug-in dimmer that sits between your wall socket and a lamp, then takes orders from a smart-home hub over a low-power radio link instead of Wi-Fi. That radio link is both the appeal and the catch. It keeps your home Wi-Fi network uncrowded, but it also means the plug is deaf until you pair it with a hub.
Check your hub before you check anything else
These dimmers list the hubs they work with — SmartThings, Wink, Vera, Fibaro, Homeseer, 2GIG, and Hubitat all appear across the models here. If you own a hub that is not on a given plug’s list, that plug will not join your network no matter how well it dims. Confirm your hub’s name on the module’s spec sheet first, then compare features.
Match the wattage to your bulbs, not just your lamp
A dimmer’s headline wattage figure often applies to old-style incandescent bulbs only. LED and CFL bulbs typically carry a much lower ceiling on the same plug, so a lamp full of high-wattage LEDs can run into that smaller number even when the total load looks low. Read both limits on the spec sheet and add up what you intend to plug in.
Outdoors or indoors changes the answer
An IP65 housing (a sealed rating that keeps dust out and shrugs off water spray) lets a dimmer live on a patio or under a porch eave. An indoor plug has no such seal and belongs near a bedside table or behind a sofa. Match the plug’s rating to where the socket actually is: IP65 for a patio, an unsealed indoor plug for a bedside table.
Think about the socket you are giving away
A plug-in module eats wall space. Some sit flush and block the second outlet, while others set the socket on the side so the top socket stays usable. In a room with one duplex outlet, that difference decides whether your phone charger still has a home.

Detailed Reviews
1. Leviton Decora Smart Dimmer Plug, Z-Wave, DZPD3-2BW, White
Our pick — 4.0+★ from 350+ verified ratings; the strongest balance of quality and price.
The plug that returns to its last on/off state after a power dip.
Memory is the quiet hero here. Leviton builds in protected memory that keeps the ON/OFF state of whatever is plugged in, even through minor power fluctuations — so a lamp settles back the way you left it instead of snapping to some default. For a bedside lamp or a living-room floor lamp you dim every evening, that one trait removes the small daily annoyance of resetting things.
The electrical side is solid rather than flashy. You get a polarized 300W-120VAC NEMA receptacle designed for table, floor, and hanging plug-in lamps, wired to a 2.5 A current rating. That ceiling is the lowest of the three here — the EVA LOGIK outlet carries a 500W rating, so a heavy incandescent load favors the other pick. For ordinary LED lamps, 300W is more headroom than most people ever touch.
What wins people over is reliability, and it is the trait the review pages return to again and again. The plug pairs cleanly with SmartThings, Wink, and Ring Alarm, and owners regularly set custom on and off times without fuss. A few report the dimming itself is uneven with CFL bulbs and that local dimming behaves differently from dimming through the hub — so treat CFL loads with caution and expect to do your dimming from the app. This is the most popular pick of the three, holding 4.0+ stars across 370+ ratings against the 111 of the outdoor model.
Where it holds its ground
- Protected memory keeps your lamp’s on/off state through minor power dips
- Works with SmartThings, Wink, and Ring Alarm from the start
- You can disable the status LED so it does not glow at night
- No flickering noted across the review record
- 5-Year Limited warranty, designed and supported in USA
What to plan around
- 300W ceiling is the lowest of the three picks
- CFL bulb dimming draws complaints
- Needs a Z-Wave hub — a bare Alexa speaker will not run it
Buy this if: you want a lamp that quietly keeps its last state and you mostly run LED bulbs through SmartThings or Wink.
Look elsewhere if: you plan to drive big incandescent loads or dim CFLs heavily.
2. Outdoor Smart Dimmer Plug
An IP65 dimmer built to sit on the patio through rain and dust.
The reason to choose this one over the Leviton is placement, not feel. The Minoston MP22ZD carries an IP65 housing — a seal rated to keep dust out and tolerate water spray — which lets it sit outside by the porch, in the garden, or beside the grill where an indoor plug has no business being. That alone puts it in a category the other two cannot enter.
Inside that housing the electronics are current-generation. It runs Z-Wave 800, the newer radio generation with tighter security against unauthorized access, and it can reach up to 1300ft in open range if your hub supports Long Range pairing. Dimming runs 0-100% and answers voice commands through a hub, and you can build daily timers or on/off routines so landscape lights switch themselves off instead of burning all night.
The power numbers need a careful read before you buy. The plug handles 400W for incandescent bulbs, but only 150W for LED and CFL — so a long run of LED string lights must total under that smaller figure. Connectivity is what the review record praises, with owners reporting quick pairing to Hubitat and SmartThings; the dissent is over range, where some find the signal does not travel as far as hoped in a real yard. It also cannot pair directly with an Echo Plus, only through a Z-Wave certified hub.
Where it earns its place: there is no other way to dim outdoor string lights from your phone without running new wiring, and the IP65 shell plus 0-100% control covers the whole job. FCC and ETL listed, with a 908.42MHz Z-Wave frequency that keeps it off your Wi-Fi band.
The honest limit: 150W for LED and CFL is a real ceiling, and range complaints mean a far corner of the yard may need a repeater nearby. Pair it close to the hub, then move it.
For the patio and the porch: string lights, landscape fixtures, and a fountain pump that need a dimmer outdoors.
Step past it for: a purely indoor lamp on a big incandescent bulb, where the Leviton’s indoor design and extra indoor-tuned controls make more sense.
3. Z-Wave Smart Dimmer Outlet, Indoor Plug, Hub Required
The one that leaves your other wall socket free.
Most plug-in dimmers eat the whole duplex outlet, and this EVA LOGIK ZW39 was designed to avoid that. Its socket faces sideways instead of jutting out, so you plug it into the bottom outlet and the top socket stays available for a charger or a second lamp. In a bedroom with one outlet behind the nightstand, that is the difference between this and a fight over space.
It also pushes the most power of the three. The ZW39 is rated up to 500W — against the Leviton’s 300W — which gives you real headroom for higher-wattage incandescent and halogen lamps as well as LEDs. Brightness adjusts across 1-100%, either from the hub or from the button on the outlet itself. Plugged in, it doubles as a signal repeater that passes your Z-Wave mesh along to other devices, though it boosts the reach of the signal, not its raw strength.
Here is the part to weigh honestly. The review record for this plug is genuinely split: many report it pairs easily with SmartThings and dims without fuss, while a smaller group describes units that stopped behaving after a few months and dimming that felt erratic. A module like this is also dependent on your hub — it works with SmartThings, Vera, Wink, Fibaro, Homeseer, 2GIG, and Hubitat, and will not talk to an Echo Plus directly. Set expectations accordingly and it delivers solid value, with the side socket and 500W rating as its two sharp advantages over the Leviton.
The standout spec: 500W at 15 A, in a body that still leaves the top outlet usable — nobody else here combines those two.
The real question: reliability is the mixed part of its record, so buy for a room where a hiccup is annoying, not a room where a lamp failing would matter. It is ETL and FCC listed, which covers the safety basics.
Reach for it when your outlet is scarce and your bulb is a heavier incandescent or halogen.
Think twice if you want the most settled track record in the room — the Leviton has that edge even with less wattage on tap.
Know the Specs
Wattage Rating and the LED/CFL Split
A dimmer’s wattage tells you how much bulb it can safely carry, but the headline number usually applies to old incandescent bulbs only. LED and CFL bulbs draw power differently and often carry a lower ceiling on the same plug — the Minoston, for example, lists 400W for incandescent but only 150W for LED and CFL. Add up every bulb on the circuit and compare against the smaller of the two figures you need. Go over it and the module can run hot or behave badly.
IP Ratings and Where a Plug Can Live
IP65 is a two-digit seal rating: the 6 means dust-tight, the 5 means it tolerates water spray from any direction. That is what lets the Minoston sit on a porch or patio. An indoor plug has no such rating, so keep it under a roof and away from splashes. The seal does not make a plug submersible — it just means a rain shower or a garden hose mist will not be the end of it.
What Z-Wave Plus and Z-Wave 800 Actually Buy You
Z-Wave is a low-power radio mesh — a network where each plugged-in device relays messages for the others. Z-Wave Plus tightens the certification, and the 800 series adds stronger built-in security against unauthorized access plus optional Long Range pairing for up to 1300ft in open air. None of it replaces your hub; it simply gives the hub a longer, more secure reach to the lamp on the far side of the room.
Why Some Plugs Act as Repeaters
A repeater (a device that bounces your network signal onward) extends the route your commands travel, not the strength of the radio itself. The EVA LOGIK outlet is explicit about this distinction, and it matters: a repeater can get a weak corner connected, but it cannot power through heavy walls on its own. Placement of the hub and the nearest repeater does most of the real work.
