One more point, on the side of must Power Supply there is a red switch that you will need a small screwdriver that you will need to push to 110V from 220V. Because these Power Supply are used world wide they have two settings to accommodate European or USA power.

Formula
Power 19.2W Per Meter
5M Per Reel
19.2 X 5M in a Roll = 96W Per Reel
96W X 4 = 384W
384W X 20% = 76.8W round up to 77W
384W + 77W = 461W round up to 500W Power Supply

A good lapel microphone is really not expensive. Never compromise on the quality of audio, especially since most of your views will come from watching on a phone.
Thanks for info.

[niggblehlm]

finally someone who actually explained the most confusing part of custom rgb led lights. Thank you!

[Beemerboy]

I had figured this out but I wish I had watched this first. It would have saved a lot of time.

[AshIsh-bhky]

Dear Sir,

I don't subscribe easily, but you and your content deserved to be subscribed!😊

[phillipzx]

Higher voltage would draw less amperage. The wattage (power) remains the same. Lower amps lets you get away with smaller wires. Other than my nit pick, excellent job.

[RealtyByLance]

Great lead up to the latest video! Good explanations!

[Avstaxx]

Thank you very much that was very helpful

[suntzu]

Thanks boss, great video. Nice shirt!

I think youre one of the only videos on youtube about this topic!!

[kevinhazel]

AS USUAL...GREAT VIDEO CONTENT! KEEP UP THE GREAT WORK MY BUDDY!

[supermum]

That has helped me a lot! How do you connect all four reels to the supply

[PreritBhatnagar]

Great explanation. Thanks.

I am a novice and need help.

I am trying to set up a led accent wall and here is my design.

I have "4" 12V WS2815 LED Strips of 5 meters each with 60 LEDs/Meter so a total of 1200 LEDs.

I want to place two strips on the left side of the wall and 2 strips on the right side of the wall. All strips should run the same effect when powered on.

I have a single PSU unit. How can I connect all these 4 strips to PSU and to Athom LS-8P controller such that they have same effect when powered on?

[JPMNRB]

Thank you so much, I almost threw away the bag.

[mariohenderson]

Hey Clem is possible to use cat 6 wire with 24 v RGB W with 5m strips

[KeyIntelMedia]

its bizarre that the 5v ws2812b draw more power than 12v ws2815

[saleemmohammed]

Hi, how do you work out what total watt led driver i need for a 10 metre 24v rgbw led strip pls.

[JodyWright-jbtl]

I’ve got a Razer back neon sign 10inch by10inch How do I covert it from 120v to 12v

[FASTSIGNS]

how many amplifiers would be needed to connect multiple rolls?

[Dahna_]

what if you didnt have the package with the label? and say you had a foot or so of an led strip? could you count the number of led diodes and calculate it and figure out how many watts you needed? how would you go about that?

[metallicaandchimaira]

How do I get that information if my LEDs do not tell me any of that information?? My LEDs did not come with that label and when I go on amazon to find out the W/m it doesnt say anything on that. How do I figure this out? Im running WS2811 addressable LEDs

[dollarplans]

I didn't read every comment but a couple questions.... In your example you said you need 500 watts.... Would you personally use a 500 watt power supply or can you or would you use 2 - 250 watt power supplies one at each end?....

I thought in another video you mentioned putting a power supply at each end so the farthest leds didn't go dim. But maybe that was only if you had a weaker than needed power supply?....
