Can I use it, to Dim 12 V. LED Lights with 4 amps Load ?

No. I will basically give you an on/off for a light. Look for a light dimmer which regulates voltage.

The PWM works well with current modulation. The LED will work at a given brightness at a wide current range so long as the LED is seeing the specified Vf. It my be possible to control a dimmable LED circuit but not the LED itself. Are you looking to control the LED for a battery operated portable light? If so there are better choices to regulate brightness of the light.ThanksTony

You may want to have a dimmer on some lights, and none on others which would be possible with the two separate outputs. I'm not sure whether drawing all of the amperage capacity from just one output would cause a problem or not.

no, the dimmer needs to be in the 12 volt circuit, so after this power brick. you will need to rewire your wall dimmer so it feeds 12 volts to the led light strip.

No. You need a dual dimmer that has two 300 watt circuit capacity. toal of 600w rating. try this oneLeviton 6628-W SureSlide 300W Per Circuit Incandescent or 300VA Magnetic Low Voltage Dual slide-to-OFF Dimmer, Single Pole, White

I would suggest not to try. The LEDS are most likely wired is some sort of series/parallel circuit to reduce the curent each LED "sees" when connected to 12 volts.

Yes, but you have to have a low voltage dimmer switch. Very hard to find>have not found one.

You can as long as the strips are connected in parallel. Keep the output rating of the strips in mind as this dimmer is rated at a max of 2A. Pulling more than that could be dangerous

I do not know if this will work for 12 volt LED lights. I cannot advise you on that at all.

I'm not sure if there is such a thing as a 12-volt dimmer, but that's the answer if they exist. I'm not aware of any 12-volt LED's that come in less wattage than this one.

This is a 12 volt. Switch, if your item is 12 VDC & drAws less than 2amps it should work. If your lite is more than the 2amps get a dimmer from electric outlet store. Van

definitely not. this has an internal circuit board that changes the voltage from 120VAC to 12Volt. This means the light won't dim it will simply turn off.

The lighting strips operate on 120 volts. I don't think they can be dimmed.

I'm not sure. I'm not using it on a dimmer. I would guess you can but not from personal experience.

No. You must use a decent dimmer that's led capable. The old dimmers are hard on the electronics in the led

Id recommend the 12 volt for optimum lighting. If you use a lower voltage your lighting will be dimmer.

You can do it both ways, I do it on the 120VAC side because the dimmers are good quality and fit in a standard electrical box ,a lot of the low voltage dimmers are different and wont fit in the box , I have done many installations and I use this dimmer http://www.homedepot.com/p/Lutron-Toggler-600-Watt-Single-Pole-3-Way-Eco-dim-Dimmer-White-TG-603PGH-WH/100663449?N=c34i#.Uo_ntWTF36A

Sure, if you are good with electrical stuff I see no reason why that wouldn't work and sounds like a good idea to me. You'd just have to splice into the existing wires, perhaps pre-tin, butt splice, and using shrink tubing. The dimmer is fed low voltage since it is inline with the transformer output, so not sure if a low voltage style dimmer is req'd, or if you can get by with a standard 120 VAC one (that part I have no idea).
