What is better 12V or 24V LED lights?

24V is better suited for LEDs. Typically, a 12V LED strip is configured with 3 LEDs in series per string. At 3V each, the total LED voltage is only 9V, or about 75\% of the total voltage. In short, a 24V LED system can actually reduce inherent electrical design inefficiencies by more than 50\%.

Can LED lights run on 12V?

The strip lighting says it uses 1.5W per foot so I’m expecting that I’ll need to provide about 2A. I was really hoping that there would be a ready made product to regulate the current efficiently, but so far no luck (if you happen to know of a product available to do this I would really appreciate a link).

How do you know the voltage of an LED?

How to find voltage and current of LED

1. The easiest way is to look it up in the datasheet.
2. You could find the LED voltage by using a multimeter with diode function.
3. You could connect a battery to the LED and a potentiometer.

Can I run a 24V LED on 12V?

If you’re trying to go the other way and connect a 12V power supply to operate 24V LED strips, unfortunately, you are out of luck. The reason is that a 24V LED strip has 6 LEDs in series per group, and there is no way to “split” this to match a 12V power source.

How do I know if my LED strip is 12V or 24V?

12v LED strips almost always have half the distance between cut points compared to a 24v strip. e.g., If on a 12v strip the cut points are 50mm apart, then the 24v type would have 100mm spacing.

Can 12V LED lights be wired in series?

a voltage of 12Vdc; the forward voltage of each LED at 700mA is 2.98Vdc. Rule number 2 from the series circuit bullet points proves that 12Vdc isn’t enough voltage to run all 9 LEDs in-series (9 x 2.98= 26.82Vdc). However, 12Vdc is enough to run three in-series (3 x 2.98= 8.94Vdc).

How many volts does it take to power an LED light?

One question that people who are new to circuits usually ask is, “how many volts are needed to power an LED?” “It’s usually between 2 and 3 volts and it depends on the color and type of LED”, says MIT Electrical Engineer grad, Luz Rivas.

How many volts does a 12V LED strip use?

This is approximately 7.5V for 12V LED strips, and 15.5V for 24V LED strips. This is a bit counter-intuitive, since this implies that you cannot simply expect a 6V power supply input on a 12V LED strip to simply produce half the power.

What is the minimum threshold voltage for LED strip lights?

What we first notice is that the LED strips do not light up until a minimum threshold voltage. This is approximately 7.5V for 12V LED strips, and 15.5V for 24V LED strips. This is a bit counter-intuitive, since this implies that you cannot simply expect a 6V power supply input on a 12V LED strip to simply produce half the power.

How many watts per foot do LED strips produce?

You will see a fairly linear relationship between 1.0 watts per ft and 5.0 watts per foot. What we first notice is that the LED strips do not light up until a minimum threshold voltage. This is approximately 7.5V for 12V LED strips, and 15.5V for 24V LED strips.
