CCT is the color temperature of a LED. 2700K is warm, 3500K is medium, and 5000K is cool. Some fixtures are fixed color, others offer tunablity.
In this short tutorial, you will learn how to wire LED fixed CCT downlights into our DC low voltage lighting system. We use lower cost awg20/2 or awg18/2 wire and remove all electronics from the fixture, eliminating all single points of failure.
This video is for fixed color installations - the series wiring method shown, allows tunable white using the same one pair wiring method - so either fixed or tunable can be installed at trim. See • ATX LED DL-120 LED fix... for an example of tunable white.
For projects with the lowest cost, where perfect diming and highest efficiency is not a priority, please see our wiring diagram for details on a parallel wired, alternative with acceptable ( not perfect) dimming or even driverless simple On/Off.
The wiring diagram is shown here:
atxled.com/pdf/-AN-How2wire.pdf
Use our wall switch dimmer/driver with 3000:1 dimming for flicker free, perfect dimming from either 120vac or low voltage power sources.
This video covers the series style of wiring, which is the most common method used with our dimmers, series wiring allows either fixed color temperature installations, or tunable white installation, with just one pair of 'skinny' wire. The DR1 shown has a 20:1 dimming ratio for fixed color installations. Upgrade at Trim to a DR2 for 3000:1 and tunable white - with the same single pair of copper installed at rough.
notes:
inside each fixture is a LED array of 3 x 11 - and nothing else - no single electronic part to fail. So, unlike a christmas tree string, these fixtures would require 11 LED chips to fail open before the string is dark, if they fail shorted - the string remains on. After 5 years, we have no installed fixture failures, because we moved the driver away from the heat.
The wire is 20/2 thermostat wire - 3 lbs / 250 ft. 14/2 Romex is 15 lbs/ 250 ft . 18/2 is 1/4 the price of Romex, 20/2 even less.
Using two wires, and having nothing smart or expensive in the fixture is revolutionary. Perfect 1000:1 dimming ratio, no flicker and no PWM artifacts, and the heat of the fixture does not cook the driver since it is at the wall switch 15 ft away nice and cool ( and dry for outdoor projects ).
Romex is 3 wires - 9 junctions per can in 3 wire nuts. Our fixed color fixtures have only one dual conductor strip/poke connector - much faster to wire

yes yes yes to this... why isn't everyone doing this... I just saw a new development where LED lights were installed and there way 120V going to each light... each led light had it's on transformer/inverter.... it seems like such a waste of hardware... both the junction box and the 12 gage wire so unnecessary for each light.

Why??? Now if one light fails, they all fail. You also still need to run two conductors to each light so nothing is saved. Again, WHY?

a) Tungsten bulbs fail open, LEDs are completely different. Inside our fixture is a LED array of 3 x 11 - and nothing else - no single electronic part to fail. So, unlike a christmas tree string, these fixtures would require 11 LED chips to fail open before the string is dark, if they fail shorted - the string remains on. After 5 years, we have no installed fixture failures. b) the wire is 18/2 - 3.5 lbs / 250 ft. 14/2 Romex is 15 lbs/ 250 ft . 18/2 is 1/4 the price of Romex c) two wires, tunable white and nothing smart or expensive in the fixture is revolutionary.

@@atxled7490 But again, why? You can do the same thing using low voltage and running them in parallel if the voltages are correct. I understand your points about trying to save a few pennies on cable and wire nut costs, and moving the drivers from the fixtures to the dimmer--which has some merit. But series wiring is just a bad idea for permanent installation.

@@audiobrad99 Here are the documented results. A UV LED chip diode Vf ( typically 3v ) is a function of temperature, and the Vf falls into a bell curve of distribution. Thus, no two diodes start with the same Vf, and if not thermally matched and wired in parallel, the one with the lower Vf gets more current, creating a negative voltage thermal runaway. Multiple 12v bulbs ( say 4 leds of 3v each in series ) wired in parallel have been tested over time, to easily reach 40% disparity, as the bulbs reach different temperatures. On top of that, different Vf results in inconsistent dimming at low levels. Also, since wire resistance is non-zero, bulbs further away have lower initial voltage, which gets worse as upstream LEDs heat and lower their Vf, resulting in being starved of delivered energy. The resulting lumen output is all over the place. Strip lights at 12v handle this by using 3 LED chips ( 9v) and a resistor to balance the current. This then consumes 25% of the energy - wasted. Take apart any dead LED and study the failure cause, its the driver, usually the capacitor, that has failed, the LEDs are fine, not open circuit. So, why waste energy, and copper, by applying the tungsten failure mechanism to LED technology?? Binning the LED die, and removing the driver, results in proven highly reliable and highly efficient devices that save money. and offer perfect dimming, since each fixture receives the same current, and lumen output is a function of current, the voltage being a side effect of temperature and manufacturing tolerances.

​ @ATX LED I'm an engineer, so I understand all that. But you basically just pointed to the advantage of putting the driver at each fixture (reminds me of the battle Tesla and Edison over the merits of using AC vs DC for distributed power). No fixture is "starved" when wired on a 120V circuit--each fixture is unaffected by the others. I appreciate your knowledge of LED lighting technology, but as I am currently wiring my new house--including some 40+ recessed LED fixtures, I just can't see using this system in our home. Plus, every recessed light circuit has from 1 to 14 "cans", AND some circuits feed other types of lighting--including incandescent in a few places. I have already chosen certain types of dimmers (some smart) to accomodate the unique needs of each room. I'm sure you have ways of accommodating a wide range of applications, but based on what I see--and the wide range of reliable, low cost 120V fixtures available, I think it's going to be an uphill climb in the building and remodeling industry. While I do see a future for low voltage wiring, it would need to be plug-n-play such that no electrician (or homeowner) has to figure out complex series and parallel grouping. Plus, consumers and designers appreciate all the options available from companies like Lutron, Leviton, and others. I went to your website and get what you're trying to do, but personally, I don't want to be an early adopter on installed technology that can't be easily replaced.

@@audiobrad99 Our customers tell us they said the same thing about plumbing with Pex vs Copper. It requires training, but once trained, nobody goes back. For you, building one house, once you select an AC bulb to communicate with an AC dimmer without flicker, and you don't mind that dimming below 10% doesn't work, and you don't have interest in tunable white that works without configuration, ( see our tunable white video kzfaq.info6vi1RCfkSyw ), then the 130 year old wiring method ( introduced at the Chicago worlds fair in 1893) is good enough. Those electrician customers who don't watch all the videos stumble and curse on house #1, and by the 3rd house they are wiring faster than Romex, so training is required, but every 3 years NEC changes the regulations, so training is ALWAYs an ongoing requirement, hence the CEU system. Here in Austin, Romex is locked up at home depot because of the extreme cost, and our customers save more than pennies on this system in the multi unit projects they build.
