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

Will a 10A power supply damage a 5M 5050 LED Strip and Controller?
Do you have a video on installation instructions on Parallel LED Strips and on Series LED Strips (how to hook everything up)?
+AzraelPercussionNEO Hello, unfortunately we do not however all you need to do is run the strips back to the same PS or Control option that you are using.
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
Hello Christopher, definitely match the voltage of your strip, if the LED strip is constant voltage and you go to higher voltage you will burn out the components. All you require is more amps/watts, your initial assessment is correct. Here is a link to the power supplies we offer, we carry MeanWell which is high quality, trusted brand of power supplies.sirs-e.com/product-category/led-lighting/led-strip-lights/led-power-supplies/power-supplies-led-power-supplies/
get a higher amp supply. the leds will only draw as much current as is needed so should not heat it up at all if you calculate correctly
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
Hello, that 110V-220V is the input allowed by the transformer not the output, this is the case at least with out transformer I can't say this is for sure the case with yours.
How do you determine your "Safety Factor" when using your equation you presented later on the video?
Hello +AzraelPercussionNEO, we define the "Safety Factor" as the percentage that lies inside the safety margin to use a power supply under normal conditions to avoid issues in the future. These issues may include overheating, loss of efficiency, unreliability or even burned power supplies. To avoid these risks, we use a "Safety Factor" where we recommend using the Power Supply at 50-75% of its capacity to improve its chances for prolonged optimal performance. In summary, if you're using a small power supply (100W or less) you can use a Safety Factor of 0.75 (75%) and if you're using a bigger power supply (100W or more) we recommend using a power factor of 0.50 (50%).
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 .....and 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 ?
Hello Inter Suficience, it sounds like you're trying to build your own LED Power Supply. 4 meters of LED strip might have different current ratings, since we carry different color and/or density LED strips; so calculating the exact values for a AC-DC converter will get tricky. The easiest thing to do will be getting a 12V LED power supply, which already contains an AC to DC converter like the bridge rectifier.

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?
with 2 amps you can run only 2 meters. Those led strips consume 12 Watts per meter so 2 meters would consume 24 watts which equals to 2 AMPS. To measure watts and amps you have to multiply Amps x Volts = Watts or you can divide Watts ÷ Volts = Amps. Hope this helps
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?
As long as it is 12V it can be used.
SIRS Electronics Inc Thanks, just so I'm clear...what does a 'driver' have that an adapter doesn't?
Some people call them drivers, others adapters. Generally they are the same thing.
SIRS Electronics Inc Okay, thanks guys!
When i measure ampers with multimeters on smd 5050 led strip lights i found less ampers that showing on data sheet. Is that normal?
Hello, it is possible, if it is a drastic difference I would reach out to your supplier.
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
Hello Agus, basically you will for sure need a larger PS, if your whole run is consuming 72W then I would recommend a 96W PS or larger, here is a link to our PS page. sirs-e.com/product-category/led-lighting/led-strip-lights/led-power-supplies/power-supplies-led-power-supplies/
how many light strip you can run in series with out using any amplifiers
Khalil Barakat, thank you for your question and for your comment. Without using amplifiers, for a basic linear installation you can use 2 LED Single Density LED strips (10 meters, 30 LED/Meter) or 1 Double Density LED strip (5 meters, 60 LED/Meter).
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?

Hello, I dont believe that should cause you any issues.
when DC power supply will be connected with led strip then any voltage range of DC supply should i maintain
This will all depend on the power consumption of the fixture you have.
I have 18 W LED strip.When 12 to 18W range LED driver is used with it ,LED strip is not glowing. Another same type 18W LED strip is glowing with sa,me driver.so plz help me to know what type of problem may happen with that strip which is not glowing..All the LEDs of that LED stip are glowing individually.. please help me..
Check the polarity to make sure the positive and negative work correctly, as well I don't know the nature of your fixtures, I recommend contacting the manufacturer or seller of the strips.
Does the "LED Density" on the Data Sheet is the Length of the LED Strip?
+AzraelPercussionNEO Hello, and no it does not the length of all of our LED strips is 16.4 ft.
+AzraelPercussionNEO, LED Density refers to how many LEDs per meter of strip are there. (i.e. 60/m density neans there are 60 LEDs per 1 meter of LED strip)
do strip light cost a lot of money in electricity 5 amps
They do not, they are a low voltage so you actually save money in the long run.
I liked your video so much I recommended to an idiot I have been dealing with who insists that the amperage doesn't matter , or how many led strips you run as long as it's 12v. What a dunce . He claims he is using a 12v 2amp power supply on a 5m rgb 5050 controllable led strip with no problems. I say run it on full white fo a while. What do you think, weenie roast or explosion?
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 :$
Light Output (Lumens) is a totally different factor correct?
Hello +AzraelPercussionNEO , you can approximate power consumption per feet by dividing the total consumption of the strip by the distance in feet. But for a more exact value, is better to measure the power consumption of the exact length to be used (i.e. 1ft, 4ft, or 10ft), if the measurements are a critical factor for your design.
Also, the lumens (luminous flux) is not a big factor in power consumption, but it is a factor for quality design and they both come in handy when designing high quality projects. The luminous efficacy (lumens per watt) of a luminaire is what "defines" the efficiency of an LED strip or any other LED fixture. So basically, you need the lumens and the power consumption to know the luminous efficacy of the LED strip and know how efficient it is.
+SIRS Electronics Inc So just because an LED Strip has a high Power Consumption (Watts) doesn't mean it will not produce a high Light Output (Lumens) correct? A good example of this is your standard card Halogen Headlight Bulb. 100W = 3200 Lums (Halogen Bulb usually). 45W = 4500 Lums (just an example of my VLED's LED Headlight Bulb)
+AzraelPercussionNEO Yes sir that is correct the light output as well has to do with the quality of the components, please check out the link below to see our high quality LED strips.sirs-e.com/
40W. Power supply how many led we can connect???
Hello, that all depends on the consumption of the LED's, if you are unsure reach out to your supplier.
Fail. RGB strips. Without buying controller please.
+Arnis Tarassu Thank you for watching our video and your comment, however please explain your question a bit further in order for me to assist you.
+SIRS Electronics Inc Measuring one-color strip does not explain how to measure RGB strips. Also measurement should be made before using controller (so no controllers allowed).
+Arnis Tarassu While yes with an RGB you would have to measure each color individually, the process remains the same. As well in our video we did not use a controller or state that one is needed to measure power output.
+Arnis Tarassu No controllers where ever even used. RGB strips where not even used in the video! This is video describes how much Power Consumption a single color LED strip (and I am almost positively sure it is the same thing when measuring Power Consumption for RGB strips as well) a LED strip consumes in Watts. Watts (Power Consumption) = Volts (Potential) * Amps (Current). Keep your commenting and questioning simple good sirs.
