- LED RGB Strip - Addressable, Bare (5m)
images are CC BY-NC-SA 3.0
Description: These are bare addressable 5 meter long 5V RGB LED strips that come packed with 60 WS2812s per meter. As these are bare LED strips that have no protective coating, your project won’t be water proof but there is access to each WS2812 LED and each strip length can be easily modified. You will be able to control each LED RGB individually giving you the ability to create cool lighting effects for your car or perhaps under cabinet lighting in your kitchen!
Note: These come in 5m segments on a reel. They are preterminated with 0.1" spaced 3-pin connectors as well as a 2 wire power connector, as shown in the pictures.

What’s the exact width of the strip, in mm? I just need to know if it’s <= the pitch of the pixels, to determine whether it’s possible to make a grid of square pixels.
Can anyone say the difference between the ws2182 and the ws2182b? The reason i ask is the 1m units are out of stock but i see ws2182b 1m units on other sites. Trying to figure out if they are same product. time is critical, otherwise i would wait for them to be back in stock.
The strips should work the same. From another user’s comment:
Interesting. You can buy 5 of the 1-meter sections (at $19.95) for $99.75… but the 5m section costs $99.95… plus you get more connectors with the 1-meter sections. Hmmm…
Thanks for the heads up on this ;)
Do these have anything to do with adafruit? Their site seems to claim they make them, but I see addressable led’s available in a variety of places and can’t tell if everyone is a reseller or if someone in the US is actually manufacturing them.
I know Adafruit uses the same LEDs (WS2812/WS2812B) in their Neopixel line which I believe they did design. I’m not sure if they designed a similar strip to this or not. We do not get these from Adafruit and as far as we know there is no affiliation with these strips. Also, these do not seem to be manufactured in the US.
I like to connect these leds with 4 or 5 meters of spaces between them in 550 groups. each group containing two led’s. So in total 1100 leds will be connected to each other. Do you think I will have signal loss over somewhere?
How much current is safe to run through the strip? If I get a 20A power supply to run a 5m strip, how often (how may meters) should I connect power?
Adafruit have a lot of content on how to deal with these (they call them ‘NeoPixels’). They recommend powering them in 1m lengths, so connect every metre. 20A will be fine driving 5m of these at peak.
What battery pack, volts and amp, is ideal to run 5m length? I will primarily be cycling between blue and purple lights only,.. any idea how long the battery will last on one charge per amp?
The typical driving voltage of these strips is 5V. The drive current varies based on colors and I/O. I/O is nearly negligible, and for colors you mention blue and purple. If I assume the latter to be magenta at full brightness, that’s about 36mA per pixel.. let’s roll with 40mA to be on the safe side. 40mA times 300 pixels, gives 12A. Yes, 12Ampère. Even the beefiest of battery packs SFE carries isn’t going to cut it. These strips are basically not made to be battery-powered - at least not at the full 5 meter length :)
What were you hoping to accomplish with this? There may be more suitable alternatives - and if not, further discussion on powering it can always be had :)
As asked on the waterproof ones, if you turn all on full you get 18A. This obviously won’t support that so what would the limit be?
As for the “this obviously wont support that”, you have to remember to jump in additional current every couple meters. With that in mind, I have personally driven various WS2801/WS2811/WS2812 modules & strips up to >60A… no issues at all.
Other than frame-rate issues, I see no reason you cannot go for creating a Ultra-HD display with these things. I mean shoot for the stars, right?
You would pay about $3331 for a 100x100 matrix. So, $300 grand or so for a 1280 x 720 matrix. Looks like Kickstarter numbers. :-)
What are the restrictions for cutting these? From the pictures it seems you can cut them at any length (not limited to sections of three LEDs). Also, the link for the Product Video doesn’t work (video was removed).
You can cut them down to single LEDs. Basically they provide two sets of pads that you can cut between. Or on the flip side, if you want to put them back together, the pads are close enough to just use a solder-bridge for re-connection.
