# Question: Can DC LEDs Run On AC?

## How many LEDs can a 12v battery power?

So, a 12V battery wired to four 3V LEDs in series would distribute 3V to each of the LEDs.

But that same 12V battery wired to four 3V LEDs in parallel would deliver the full 12V to each LED – enough to burn out the LEDs for sure.

Wiring LEDs in parallel allows many LEDs to share just one low voltage power supply..

## Do LED strips use a lot of electricity?

LED Tape vs Traditional Lighting The potential savings are very significant – LEDs draw up to 85% less electricity than conventional incandescent lighting, and around 18% less electricity than CFLs (Compact Fluorescent Lamps). Even at first glance, these savings look impressive.

## Can 12v AC kill you?

So, no, 12 volts won’t kill you. Car batteries’ terminals are typically exposed to human touch, why? Because 12 volts is not dangerous even though the battery be capable of 500,000 ma! … You often hear it said that it’s not the volts but the amps that kills.

## Do 12v LEDs need drivers?

Because LEDs require a constant DC of 12v or 24v, LED drivers are required in all LED systems (except those which are specifically developed to be controlled by mains voltage power supplies such as mains voltage tape or LED bulbs).

## What is the difference between 12v DC and 12v AC?

12V DC is safer than 12V AC. Body resistance decreased when the 12V AC still may cause the dead, 12V DC will not be in 100%.

## How many amps do I need for LED strip?

To find the total maximum current draw per meter, we would multiply 60mA x 10 (ten segments per meter for the 30/LED per meter strip) = 0.6 Amps per meter OR 60mA x 20 (twenty segments per meter for the 60/LED per meter strip) = 1.2 Amps per meter.

## Do I need a special transformer for LED lights?

All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally. The purpose of the transformer is to reduce mains voltage (240V) to the desired level relative to the bulb being powered (e.g. 12V or 24V).

## Are LED strips AC or DC?

Whether it’s your cell phone, laptop, or in this case, LED strip lights, you’ll need something to take the 120 volts of alternating current (AC) from your wall outlet and convert it into a lower voltage of direct current (DC) that your LED strips (or other electronics) require to run.

## Is 12v AC dangerous?

12 volt and 15 volt circuits are generally considered ‘safe’ to work on. ANY circuit(even single AA battery) that has a switching/step up/boost function should be considered a high voltage circuit. If you don’t know what it does then you shouldn’t be poking around in it.

## Can I use 12v AC instead of 12v DC?

As long as the voltage of the “DC Appliance” is not less than the 12 Volt adapter then it will either work or won’t, all in all it’s a bad idea to experiment, actually it’s a bad idea just to even think about doing it, unless you know about what you are about to do, don’t.

## Will 12v AC LED run on DC?

There is no such thing as an AC LED. There is a circuit inside which probably incorporates a bridge rectifier and current limiting resistor. If so, it will work just fine on 12 volts DC. Yes, because LED’ s really are a Direct current device light that is hooked up to a circuit.

## Are low voltage LED lights AC or DC?

Banned. thom said: Regular incandescent bulbs work just fine on either AC or DC, LED’s will work on AC if you don’t overpower them but they will be off 1/2 the power cycle since diodes only allow power to pass one way, though generally they are DC. You will have more voltage loss on long runs with DC.

## Can I use 12v transformer for LED?

FAQ – 12V Transformers and LED Compatibility. Magnetic transformers will generally work with all MR16 LED lights, albeit at the cost of efficiency and extra power consumption as was explored in this FAQ article. … They are not suitable for 12VAC (halogen or LED retrofit) lighting.

## Can you use LED bulbs in low voltage lighting?

Retrofitting your existing garden lights with LED bulbs will deliver four wins: … Ease of installation: Even though low voltage landscape light fixtures are pretty easy to replace, you won’t need to when upgrading your existing ones to LED bulbs.
