If you’re going to spend the time to install this, or pay someone to, then there’s no point in saving $20 or $40 on a cheaper power supply. Just get one of these Armacost ones or it will probably cost you more in the long run.These operate perfectly and they’re heavy, indicating that they might actually survive at their maximum rated output unlike manufacturers making dubious claims about what they can do with half as much copper.24V is much better than 12V because half the amps are required for the same wattage. That means less heat, less power loss per unit of strip/wire length, and longer runs of strip and wire become possible. So I’d use 24V whenever possible.

Purchased for a Under cabinet lighting project and installed the power supply in the attic with a dimmer switch. Unit installed easily and works well. The two legs of lighting worked well for my particular install. Unit seems to be built well and is of a solid design. Between this power supply and the selected dimmer it works well.

The media could not be loaded. My goal was to setup kitchen cabinet lights with a wall dimmer and these LED dimmable drivers are perfect. They do not cause any flicker when using the smart Kasa dimmers. My friend electrician also loves them and will recommend them for his customers since many brands disappear after some time and their products break shortly after. This brand seems to be very good. It’s also very hard to find a brand that doesn’t require a remote control or turn back on to previous state if power is cut off using a switch. These drivers do all that. I got their LED strips and mounting channels to complete my setup.

The Armacost Lighting 840600 is a high quality, dimmable power supply for 12V LED fixtures or systems.COMPATIBILITY: This power supply should be compatible with a wide range of 120V dimmers. The installation instructions state the following:"Armacost Dimming LED Drivers are compatible with both forward phase (leading edge, triac, incandescent) and reverse phase (electronic low-voltage, ELV, and trailing edge) AC dimmers ... They are also compatible with low-voltage PWM dimmers and RGB color controllers."Although virtually all dimmers will work with Armacost Dimmable LED Drivers, Armacost Lighting recommends dimmers that can be programmed or have an adjustment dial to set the low end dimming range."BUILT IN CONNECTORS: The built in connectors work well and quickly. They need to have some of the outer insulation to clamp onto, to keep the stress of any pull on the wire from going to the terminal connection itself. So don't strip too much of the inner or outer insulation.LOW MINIMUM POWER LOAD: The minimum power load is just 5 watts.VOLTAGE: Output is 12V DC.DIMENSIONS: It's somewhat large, at 7-1/16 inches long by 2-3/8 inches wide by 1-3/8 inches high.ENCLOSURES: If you want an enclosure, Armacost makes variations with enclosures for conduit connections.The only real negative is the cost, though of course having a high-performing, high quality power supply makes it a reasonable value. Lower-watt drivers are less expensive than this one.The manufacturer's website has lots more info, including specs and installation instruction.TWO WARNINGS: First, be sure to get a power supply rated with enough watts to cover your needs.Second, be careful to get a power supply with the right input voltage. Armacost makes a line of 12V dimmers and matching power supplies. This product is the universal power supply, to be used with a range of dimmers and 120V.

One of the few LED drivers that can be dimmed in compliance with the NEC for electrical inspection. The cord that came with it can be unscrewed and the driver can be hardwired with 14-2 romex. The connections are circuit board terminal blocks on each end, so they required a jeweler screwdriver. Be sure to hold the blocks when tightening the screws, so the block doesn't torque off the circuit board.The unit does soft start and ramp to full in 1 sec. Other than that, there isn't a 3 sec delay to warm up like cheap switching power supplies have before they instantly pop on at full brightness. That's nice.I had no problem using a z-wave smart dimmer. I used the a Linear aka Nortek aka GoControl model WD500Z5 zwave dimmer and it successfully burned in so far for 1 day. It does get very warm, even pushing only 10 watts. Like a hot McDs coffee cup hot. Not too hot to start papers on fire, but too warm to be comfortable holding. Plan for that when mounting.Also, If you wired several LED homeruns instead of daisy chaining the runs, be sure to plan on wirenuts or a terminal block to connect to the driver- it only has internal room for 1 #12 pair of wires. You have no internal room for other connections.I powered 10 watts of LED under cabinet LED tape. The cables in the pic are 14-2 romex and 16-2 cl2 riser cable. No issues with those gauges.

My daughter's closed did not have a light like many of the smaller room closets usualy don't. I bought a 10' led strip and powered it with this. Wired a switch through the wall to a new outlet in the closet and presto, very bright closet light.
