I want to buy 12v dc LED strips, how do I hook them to this? Is there such a thing as 12v ac to 12v dc converter? How do we hook up those strips?

Your landscape transformer outputs 12V AC. LED strip lights require 12V DC. If you need 12V DC, I recommend you get one of these to get the conversion done. It is a very small device so makes it easier to hide. You can get it from Amazon. 72W Outdoor Waterproof Low Voltage Landscape LED Power Supply Converter/Rectifier, Input 12V AC to Output 12V DC A demo is here: https://www.youtube.com/watch?v=OJzarYlOnPc﻿

Sorry, I don't know the answer to that, but the intermatic ML121RT is strictly 12 volt ac for outdoor lights. I would think you would want to buy a different transformer that would take you from 120 vac to 12 vdc.

Honestly, I don't know the answer to your inquiry. I used the transformer to power low voltage landscape lights and it works famously. As for LED strips......I haven't a clue. Very sorry.

I bought the very same setup but had not hooked it up till I saw your question. My 12 volt power supply is only good to 5 amps but the converter boosted the voltage up to 33 volts no problem and the light is blinding at 60+ watts. I didn't have a heat sink on the 100 watt LED so I could only run it a few seconds. THe buck converter has some good heat sinks on it, your biggest issue will be to cool the LED. I have used a CPU cooling fan and run my other 100 watt LED as an adjustable lab bench light maxing out at a de-rated 30 Watts, it works amazingly well. You might want to put a small fan on the boost converter as well since 10 watts of dissipated power does add up. I bought the very same setup but had not hooked it up till I saw your question.

This transformer is 12v AC output. You need DC output for your LED application.

First, are your strings of LEDs labeled to work with 12 volts? If they are both 12 volts rated, connect their wires (+ to +12v and - to GND or 0 volts) in parallel. If they are labeled to work on 6 volts, connect one - wire to GND, the + wire to the - wire of the other string, and then connect the + of the second string to the +12 volt output of your supply. Of course, you must prepare a power cord for your 120 or 220 AC service to connect to the two AC IN screw terminals. Good luck.

they are rated 7-16v ac/dc. i can tell you they worked for a short while on 12vdc, when i tested them, but when i used 15v ac mocking up the fixture, 2 fried about the 3rd time switching on. i have one working on 12vdc regulated about 5 months they have a beefy bridge rectifier internally, but it seems the ic regulator or driver is not up to the task of switched supply that comes from an unbuffered 60hz rectified feed. they would have been better off using a more traditional regulator to drive the leds

Get a light made for 12v, there are several around. To hack this light to work on 12v, remember LED chips don't run at a voltage, they run at a specific current at roughly a particular voltage. This light would want specifically 1.2A at about 24 volts. The 10 watt lights work the same way, but at 0.8 amp curret at around 12v. If you drove them at a constant voltage, current would be out of control and they would either underperform or overheat.

Since these are 12V LEDs, they require a separate 12V power supply and I suspect that the 12V power supply would not handle being on a dimmer circuit. There is a low cost dimmer available, see LE® RF Dimmer for Single Color LED Strips, LED Ribbon, RF Dimmer for 12V DC LED Light Strips, 8A, Wireless Remote Control for All Dimmable 3528 5050 LED Strip

I have answered this to another potential buyer, here are my findings: I will speak from my experience. NOTE: THIS IS NOT A MANUFACTURER SUPPORTED OR RECOMMENDED MODE OF OPERATION!! MAKE SURE YOU KNOW WHAT YOU ARE DOING!!! I had the same problem: existing 12VDC with inline wireless dimmer. I checked the construction of the lamps, they are built simply as 4 1W LED's in series, without a current limiter or constant current source. I measured the voltage of the white adapter (~12V) and the current (~250ma). These measurement are consistent with an earlier measurement made on this type of LED (3,3-3,5V forward voltage). Considering the above observations, I used 3 of these LED lamps without the white converter, in parallel, fed by my existing 12V 5A power supply: current consumption ~0.5A yielding a total power of 6W for 3 lamps. It was clear to me that this will work well in my setup, more so when after adding my 12-24 wireless LED controller in series with the lamps (my wife prefers to dim the LEDs to 40%). Bottom line: works perfectly without the white converter, using my 12VDC power supply and the inexpensive wireless LED dimmers available on line. Also: the light hue is a perfect match to the incandescent bulbs they replace, without the greenish tint of some earlier white LEDs. Will update in a few months.

I presume you mean "240 Vac electric plug". These LEDs require 12 Vdc. You will need a power supply to convert the ac input to a dc output. There are several power supplies available which will work at 240 Vac input. Do not attempt to connect these LEDs directly to 240 Vac power. They will be severly damaged.

The transformar give you the dirección how to conected, just make sure the power source for the input is 110-120VAC(volt, Alter Current) the out put for this item should be getting 12VDC( volts, Direct Current) if you are connecting an LED make sure your negative and positive are connecting right to make them work other wise just flip the connections.

These lights definitely work fine with 12VDC, and that's what I'd recommend. However, they also have a bridge rectifier built-in, so the DC polarity you supply doesn't matter, and I'd guess they will work with AC as well, although it's possible you'd get some 50/60hz flicker in the light output, and perhaps create more stress on the electronics depending upon how well the built-in regulator handles it.

Hi. For one led strip will need a 12v DC 2AMP power supply. If you need to add another one and use only one power supply for both strips, you will need a strip connector to connect both strips and a 12v DC 4AMP (at least) power supply.
1668656
No. These operate on 120V AC. You'd have to have a transformer/converter for LED lights to run them on a 12V DC circuit. Why not just run line voltage to these lights?

As far as I know there are two ways to control these light strips- using a 2.5mm center-positive 12v connection, or utilizing the 6803 controller (a much better option in my opinion.) Search for 6803 controller on here or eBay and you'll see them. These strips utilize 4 wires (V+, Gnd, Data, Clock) but also have a barrell jack connector in case you don't get the controller or prefer not to use these to their full capabilities.

These lights are also offered in 110v complete with the ground prong. However for 12v application the thrid wire is not needed. The lights like all LEDs works off of DC current. In 110v a transformer is used to change the AC current to DC current.

Splice them in with your running lights. Unless you want them blinking. I think my review of these might have a bit more detail. Just remember a 12v DC system is just one wire supplying a return path back to power source(usually black) and a 12v wire (any color other than black,or green). Green is a ground. Hope this helps.

I would recommend using the 12v dimmer after the power supply. Cutting"Dimming" the power prior to a power supply defeats the purpose of its capability to convert power from 110v AC to 12v DC.
