Find the Power Consumption of Any LED Strip

Need to calculate how many LED strips you can safely use per power supply but are unsure of how much power your LED strip consumes? If you're using SIRS-E LED strips, you can easily find corresponding data sheets that display power consumption information along with detailed technical specifications. But what do you do when you are using custom lengths or are using an LED strip with no information attached to it?

In this video Jorge demonstrates a basic test you can use in order to determine the power consumption of your individual LED strip. With this information you will be able to safely calculate how many LED strips you can use per power supply. Also, despite having similar names and descriptions, each LED strip has its own specifications and vary depending on the materials built. All SIRS-E LED strips are built with high quality materials and are designed for optimal performance. As always, we recommend that you take appropriate precautions when conducting your own test.

Formula used: Watts= Amps x Volts

My question is how much electricity is it using from the meter this seems to be a very grey area no one mentions it in led world i have 4 x1000mm lenghts of rigid 6030 led strips i used the formulas amps= power÷volts i had the power and volts so it was easy 18watts a strip x 4 strips = 72watts ÷ 12v so i rounded it up bought a ac^dc transformer 12v 5a secondary side load it says on transformer 100-220v ac 1a so this part i confused is it 1a at 100v or 220v seems alot of electricity to power 72watts of 12vdc led strips i calculat i paying from meter 240watts of real electricity this seem a very lot so in theory tbey are not cheaper to run lumins per watt can you clear tbe mains feed load out i tbink iam right

Hey, very informative video. I am running 16 feet of 5050 warm white (single color) LED strip. The strip has 60 leds per meter (so I think double what normally is on LED strips). What power supply should I get to run this amount of LEDs? Right now, the power supplies I have been using are really heating up hot. So to decrease the heat on the power supply, should I get one that has 12V output and more amps? Something like 5Amp or even 6Amp output. My electrical knowledge is not the best. If I get a powersupply with more amps will I reduce the heat generated on the power supply? If I get a powersupply with more amps will that not fry the LED light strip? thanks

To complete the question below
I try it for 2seconds, it Works. But can it WORK for a longer time?

Can a power adapter that meets the voltage and current output requirements be used? Such as a 12V 4Amp adapter from some other electric device be used to power a 48Watt strip of led lights?

Will a 10A power supply damage a 5M 5050 LED Strip and Controller?

Quick question. Bought 5m of 5050 300 12v led rgb strip for my desk, but want to cut it and leave 2m for behind my bed head. Will a 2 amp power supply be sufficient in running 2 metres worth of rgb leds?

thanks very much for your video .truely professional

Do I have any risk, if I convert the 12 V AC output of an transformer in 12 VDC by using a bridge rectifier ( 4 schotky diodes) a capacitor up to 25V in this output to conect 4 metters led strip ? Actually I am trying to calculate the exact value of components that makes me able to turn on 4 metters of led strip (12 vdc 2 A) ??
Any recomandation ?

Hi, I bought 5 meter 5050 led strip with 60 led/m. After installing & trying the led blinking after 10 minutes & I got over heat in power supply as well as the led close to power supply. The PS itself only 3.6 Amp. How many amps the power supply should I buy? I search it consumes about 72 watt & the current is 6 Amps, am I correct. And how to convert say it 100 watt 12 VDC to power consumption in 230 VAC. Many thanks

How do you determine your "Safety Factor" when using your equation you presented later on the video?

[ACSWIFT]

do strip light cost a lot of money in electricity 5 amps

[raimukherjee]

when DC power supply will be connected with led strip then any voltage range of DC supply should i maintain

[julienmorren]

Hi, I need 60w for my 5050 led strips .I have 2 transfo of 40 watt together 80watt .Can I wiring the 2 together, that will make 80 wa. Or is this wrong or dangerous?

When i measure ampers with multimeters on smd 5050 led strip lights i found less ampers that showing on data sheet. Is that normal?

[AzraelPercussionNEO]

Also how do you measure Power Consumption per feet (isn't it the longer the distance the more resistance thus more power consumed (Watts) but less light output). Little confused here :$

[AzraelPercussionNEO]

Do you have a video on installation instructions on Parallel LED Strips and on Series LED Strips (how to hook everything up)?

[AzraelPercussionNEO]

Does the "LED Density" on the Data Sheet is the Length of the LED Strip?

[khalilbarakat]

how many light strip you can run in series with out using any amplifiers

[jayankannelil]

40W. Power supply how many led we can connect???

[tarassu]

Fail. RGB strips. Without buying controller please.
