Works Flawlessly and Exactly What I Wanted

Product was used in an RV (30’ travel trailer) to dim led lights mounted on the rail of the awning. It was installed inline with the existing power switch for the LED lights, and mounted in the cabinet near the panel. First, let me say that this switch was so good I purchased it twice. I have used it to dim the outside led lights on my awning rail, and when it worked so well, I purchased a second one to install for the overhead lights inside my camper. We were able to install this switch with the simple installation method, with the red and white wires together. After using a multimeter, I determined that my awning LED lights drew 1.5A and my interior lights drew 2A. I purchased this switch since it was rated to handle twice that amperage. Installing was simple, or as simple as working with wiring ever is. The supplied wire nuts were perfect to marry this switch into my existing wiring. I did add a section of heavy duty lamp cord to allow the switch to be placed where I wanted it in the cabinet near the existing switch of my lights. In other words, the wiring on this switch is abou 4 inches long, so if you want this dimmer to be located more than a couple inches away from an existing switch it will be working in conjunction with, you may need to splice in some extra wire to give you the distance you need to relocate this dimmer. If you are wiring this as your only switch, you will need no other wiring, other than what comes in the package. I wanted to keep the original on/off switch and have it work in conjunction with the dimmer, so I need to move the dimmer a little farther away to where I had a place to mount it. The switch is very small and the locking ring that holds it in place worked perfectly, and tightened down sufficiently such that the dimmer switch itself doesn’t move when you are rotating the dimmer knob. I expect that the LED lights on my camper are not dimmable per se, since they were not orginally installed with a dimmer, but the brains of this dimmer worked perfectly to allow a full range of light from very dim to full brightness. It is nice to have the ability to have a hard click “off” position, although I don’t expect I will use that feature since I still have the original on/off switch inline. Mostly, I want to say that installing this dimmer makes my camper lights usable. The outside LEDs on the awning were WAY too bright for calm evening lounging ina campground, without lighting up the site next to me and being a nuissance. This swithc makes it so we can have enough light to lounge, and still be able to have lots of light if we need it. Regarding the inside LEDs, our camper’s lights were so bright that watching TV inside was difficult with them on. With them off, the TV would hurt our eyes. With this dimmer installed, we can adjust the interior LEDs down so that there is ambient lighting for every situation. I am so pleased at how this will make our lights so much more usable and perfect for our next trip. There is ABSOLUTELY NO FLICKERING with this switch. The LEDs dim and hold their brightness wherever it is set, with no flashing, flickering, twinkling, or other annoying nonsense, although I guess twinkling might be a nice effect at times.... :) I bought this switch because the comments and reviews seemed to indicate that the company was very helpful, but I ended up not needing them after all. Buy it. Install it. Enjoy it. Perfect.

Works great in my Thor Sprinter RV ceiling lights ( LED's) ...

Works great in my Thor Sprinter RV ceiling lights ( LED's) Red and White to 12VDC Black to the lights.

Great product, confusing instructions, works great!

Installed the switch yesterday. Instructions are worded very confusing. The first question under the questions area on the product page luckily was asking how to wire the switch. The seller responded with: 1 - Connect the + (positive) wire from the LED to the dimmer WHITE wire and to +12 volts. 2 - Connect the - (negative) wire from the LED to the dimmer RED wire. 3 - Connect the BLACK wire from the dimmer to ground. I wired exactly as described and the switch worked PERFECTLY. I would highly recommend this switch although it is a little pricey. I would definitely recommend the seller print out and include the 3 step wiring process worded above and remove the confusing instructions they currently include. Other than the poor instructions, the product is great, works flawlessly and if I need another switch I would definitely order again.

WOW! Awesome quality and customer service!

This is a fantastic dimmer - high quality parts and yet very small in size for such a capable dimmer! I purchased 2 of them, and am using them to dim multiple LED's in an automotive application. To those who gave this product a bad review, be aware that dimming LED's is not as simple as putting an inline switch between the power source and an old incandescent bulb, for example - there are lots of electronic "things" that need to happen correctly, and your LED not dimming as well as you had hoped is likely not the fault of this dimmer but your wiring of the dimmer, your LED chip, or your application itself. So instead of giving this product a bad review, either do the research on how to wire it up for your specific purpose, or call the company. I did both, and talked with a very kind and helpful gentleman who confirmed that my project wasn't what this dimmer was designed to do, but that if I wired it in a certain way (2 wires together, and the third alone - and the "flow" of electrons would need to be in a certain direction through the dimmer...), that he thought it just might work. Sure enough, it works PERFECTLY. I'm thrilled to find a company that not only makes high quality and efficient devices, but also understands how they work and is willing to take the time to help their customers install them properly. Thank you PCA Electronics - I'd give 10 stars if I could!

Awesome travel trailer upgrade

Installed these on my Grand Design Reflection TT....work perfectly and install was a breeze

It ain't cheap, but this one did exactly what I wanted it to do.

I used this controller with a smd LED strip light. I'd say the strip light draws about 12 to 24 watts. For a 12 volt circuit that is 1 to 2 amps. That is well within the stated 4.5 amp rating of this dimmer. It does exactly what I wanted it to do. It has a slight detent (a slight click like a radio volume knob) that cuts the power completely off. Then you turn it clockwise past the click and the lights slowly come up to full bright. I felt the amount of dimming seemed proportional to the sweep of the dimmer. I put my finger on the small case and it never felt warm to the touch. I consider that a good indicator that the unit is not being asked to power too much. I will say this, the instructions are a little confusing. There are different drawings for LEDs vs. other lights and it could be confusing for some - it was for me. But I found in the written setup verbage a step-by-step description of exactly what went to what. I used that and everything went perfectly. Three wire nuts were included, but they were too large for the wires I was using. I used smaller wire nuts I already had. A diode was also enclosed if you wanted to use it to control a motor. Thus far, I am quite pleased with the dimmer. I had bought two less expensive dimmers before. One worked about a week then quit. The other has no position that completely turns off the power. That means the unit is drawing battery power all the time. This one is a bit costly, but it seems to be a quality product. One caveat I'll mention. A sealed unit of this size cannot have but so much ability to dissipate heat. It is only my opinion that those who push this unit to the outer limits may cause it to fail. FYI: I've learned something over many years of working with LEDs. Some of them just do not lend themselves for use with a dimmer - any dimmer. It isn't the fault of the dimmer. It has to do with the wiring and design of the LED. Blaming the dimmer and rating it poorly in such circumstances is simply unfair IMHO. I'm writing this on June 29, 2018. I'll post an update if this thing fails.

Great full-range dimmer

Works great! I’m using it to control a pair of 18W LED headlights on a 4-wheel bike (surrey.). The headlights were too bright so this dimmer works fantastic. It adjusts output all the way from completely off to full bright very fluidly with no “steps.” It’s infinitely adjustable. Solid “click” to the off position. Easy install into my custom panel. Wiring instructions were complete and correct.

Perfect Dimmer for LED Motorcycle Driving Lights

Bought and installed this to give me the option of dimming newly installed driving lights that are extremely bright. Mounted this in an empty spot on the dash of my Kawasaki Concours and wired it in series with a handlebar mounted switch. The dimmer is smooth, very linear, solid and compact. It's also waterproof, making it a perfect choice for this application. It works flawlessly and looks good too! Very pleased with the quality and price point.

Awesome for LED lights

Have this installed in our camper van to some lights above our bed, fantastic little dimmer for the price. - I was a little hesitant but am surprised by the quality, I like that it has a click off a the end of the turn to know your lights are all the way off. - Very small and un-noticable next to our bed, some dimmers seem huge for what they do and having a small space this really helps keep things from getting in the way. I highly recommend this to anyone looking for a small dimmer for LED lights, easy install and worth the money.
