Product Description

By entering your model number, you can make sure that this fits.
LED Lights offer flicker-free dimming over a wide range of brightness. It's perfect for under-cabinet lighting because it doesn't "pop on" or "pop off."
Both 120 Volt AC dimmers and lighting controls, as well as low-voltage DC dimmers and controls, are compatible.
Connect up to 10 of the rated 20-watt maximum load – derating performance is not required
Overload protection and automatic shut-off are included in the Class 2 power supply.
Use a forward-phase CL-style or equivalent dimmer for the best AC dimming performance. The use of reverse phase or ELV may cause dimming to be less effective.
There is no minimum power load; dimming works equally well with a single 3-watt LED puck light, 20 watts of tape lighting, or a combination of both.
For use in dry or wet locations, the ETL certification is required.

Questions & Answers

Is it true that the armacost 45-pound armacost 45-pound armacost "Does the watt driver come with an ac cord?" reads the Amazon description. Despite the fact that the box in the product photos states that it is included, the item is not included. ?

Thank you for taking the time to learn more about our products. Because the 24 and 45 watt universal power supplies no longer include an AC cord, dimming with an AC wall dimmer switch requires hardwiring the power supply rather than plugging it in. This is because National Electric Codes state that doing so is a fire hazard. If you're not dimming, one of our standard power supplies, such as the 8, 20, or 60 watts, will suffice.

Is a Lutron Maestro Dimmer compatible with this?

Our AC Dimmable power supplies work with virtually any dimmer that is listed for LED use on the market. The Lutron Maestro Series is one of them. A "CL" dimmer is recommended because the trim adjustment setting aids in dimming range control. The letters "CL" are usually found in the model number of these dimmers.

When you dim the led to low light, do you hear anything (hummm)?

I'm dimming these with a Levitron LED dimmer and LED MR16 bulbs, one per bulb because they're in recessed light fixtures. There's no noise or flickering.

Is there a table somewhere that tells me what size driver I need for a certain length of lights?

The wattage of your lights must be known. The number of watts a driver can power is calculated by multiplying its volts by its amps. For instance, suppose the driver is 12 volts. as well as two amps It has the potential to produce 24 watts of power. Although you shouldn't take right to 100% capacity as much as 20 watts.

Selected User Reviews For Armacost Lighting 820200 for LED Lighting, with Removable AC Cord, 20 Watt, Gray

The electrician has given his approval
5/5

One of the few LED drivers that can be dimmed to meet the NEC's electrical inspection requirements. The supplied cord can be unscrewed, and the driver can be hardwired using 14-gauge wire. 2 romex. The connections were made using circuit board terminal blocks on both ends, which necessitated the use of a jeweler's screwdriver. When tightening the screws, make sure to hold the blocks in place so they don't torque away from the circuit board. br>br>The unit has a soft start and ramps up to full power in one second. Aside from that, unlike cheap switching power supplies, there is no 3-second warm-up period before they turn on at full brightness. What a lovely thing to do. I didn't have any issues with my Z-tools at all. Wave smart dimmer is a device that allows you to control the brightness of your lights I used a Linear aka Nortek aka GoControl model WD500Z5 zwave dimmer, which has burned in successfully for one day. Even when only pushing 10 watts, it gets quite warm. As hot as a McD's coffee cup. It's not hot enough to catch fire, but it's too hot to hold comfortably. If you're mounting something, keep that in mind. br>br>In addition, if you wired several LED homeruns instead of daisy chaining them, make sure you have wirenuts or a terminal block to connect them to the driver. Only 1 12 pair of wires can be run through it internally. Other connections are not possible due to a lack of internal space. br>br>I used 10 watts of LED tape under the cabinet.

You've got it! This power supply was purchased to power 12 feet of Armacost's 60-volt lighting system
5/5

For my new kitchen cabinets, I'm going to use LED/meter strip lights. I'm using a Lutron Caseta dimmer to power the power supply. I'm blown away by how well the countertops are lit, but this power supply, combined with the dimmer, is a winning combination. Six lighting strips, ranging in length from 12 to 31 inches, are arranged in four branches and run from the power supply's output connector. I've worked with 14 gauge wire in the past. wall- To keep the voltage drop to a minimum, use rated speaker wire. The power supply is housed within one of the cabinets and only gets a little warm to the touch. I also appreciate Armacost's comprehensive product documentation, which includes important information on voltage drop and other technical considerations. It's something I'd buy again if the opportunity arose.

A high- LED driver power supply that is dimmable and "universal" from 120V to 12V DC
4/5

The 840600 from Armacost Lighting is a high-end, dimmable power supply for 12V LED fixtures and systems. COMPATIBILITY: br>br>EXISTENCE: br>br>EXISTENCE: br>br>EX A wide range of 120V dimmers should work with this power supply. The following is taken from the installation manual: br>br>"Armacost Dimming LED Drivers work with both forward phase (leading edge, triac, incandescent) and reverse phase (electronic low-voltage) LEDs. " AC dimmers with variable voltage, ELV, and trailing edge They're also suitable for use in low-light situations. RGB color controllers and voltage PWM dimmers are available. br>br>"Although almost any dimmer 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. " "br>br>CONNECTORS BUILT IN: The built-in connectors are easy to use and quick to connect. To keep the stress of any pull on the wire from going to the terminal connection itself, they need to clamp onto some of the outer insulation. As a result, don't remove too much insulation from the inside or outside of the house. LOW MINIMUM POWER LOAD: br>br>NOMINAL POWER LOAD: br>br>NOMINAL POWER LOAD: NOMIN Only 5 watts are required as a minimum power load.

TWO WARNINGS: br>br> To begin, make sure you purchase a power supply with sufficient wattage to meet your requirements. Second, make sure you get a power supply that has the correct input voltage. Armacost manufactures a line of 12V dimmers and power supplies to go with them. This item is a universal power supply that can be used with a variety of dimmers and 120V power.

It performs the function of a transformer
3/5

With a dimmer, it does not work. Old magnetic transformers were not working properly with the new bulbs and my Lutron QS dimmer after I replaced halogen bulbs in my kitchen pendant with LED bulbs. So I swapped out the old transformers (three of them, each feeding its own 40W bulb) for this new one, which has three 6W bulbs connected in series. br>There is absolutely no dimming. It's either on or off when the light is turned on. I experimented with various dimmers and modes (the Lutron Homeworks QS allows me to switch between LED leading edge control, Magnetic Low Voltage, and Incandescent - It's the same thing, but with different bulbs. The same bulbs work perfectly with two different types of dimming transformers and dimmers - As a result, it's clear that this transformer is to blame). So, if you're looking for a way to supply power without having to dim it, this is the device for you. It's fine; if you need to dim it, go ahead. Take a look somewhere else. Other vendors' transformers work fine; I'm not sure if mine is defective, and I don't have time to investigate. Changing vendors is all it takes.
