When LEDs are placed in a series, the voltage is dispersed between the LEDs, meaning less voltage goes to each of the LEDs. This can be very useful. For example, if a 24 volt adapter were powering one LED, there'd be 24 going through that LED which is way too much for any of our LEDs to handle and would result in a burning smell/melt down. How do I hook up LEDs in series? If you look at the diagram below, you can see what it means to have LEDs in series. They share the same path, kind of like holding hands with people in a circle. Notice how the LEDs are layed out: (-) (+), (-) (+), etc. making sure that the end (-) connects to the (-) wire and the end (+) connects to the (+) wire, if any LEDs are backwards nothing bad happens, they just won't turn on. If 3 LEDs were in series with a 24V source, each would receive 8V, if 6 were in series, each would receive 4V, etc. How much voltage does each LED require? This depends on the type and color. Most LED will require anywhere from 2-4V if they are just standalone LEDs without any resistors installed. If resistors are pre-installed, like many of our LEDs, then they can handle 9-14V.   How would this apply to our products? Lets say you purchase any of our 12V LEDs, designed for 12V current and want to use in your home which is 110V AC, here is what you need to do: You would place 10 of our LEDs in series allowing them to operate off of 110V. We do not recommend doing this, as its best just to use a power supply to conver the 110V to 12V DC, but in theory it could work. However, if you had 12-24V, the below situation would make sense.
