Frequently asked questions
How long can 12V RGB neon flex run?
12V RGB neon flex runs up to 5m from a single power feed. Beyond 5m, voltage drop causes visible colour shift and dimming at the far end. For longer RGB runs, switch to 24V (up to 20m) or 48V (30m IP68 outdoor).
What is 12V RGB neon flex best for?
12V RGB is best for compact installs: signage, retail displays, cabinet and shelf feature lighting, camper/van/boat builds, and any 5m or shorter colour-changing run where a small driver and tight bend radius matter.
Are 12V RGB kits compatible with Alexa or Google Home?
Yes. Most 12V RGB kits include a WiFi controller compatible with Alexa, Google Home, and the Tuya smart-home app. Standard kits use a remote-only controller. Music-reactive kits respond to ambient sound.
Can I cut 12V RGB neon flex to length?
Yes. 12V RGB neon flex cuts at marked intervals (typically 5cm on 8×18mm and 2.5cm on 6×12mm). Cut at the marked line, attach the appropriate end cap, and the warranty stays intact.
What warranty applies to 12V RGB neon flex?
4-year warranty on the LED neon flex from ATOM LED. Controllers and remote handsets carry their own 2-year warranty. Free UK delivery, technical support Mon-Fri 9-5.

Neon flex channel
I used the channel on my recent project , I was told I needed the 10mm x 10mm for the flex I bought . But as I had to use 2 separate cut lengths of flex, it meant having a separate feed cable which I needed to hide , so I bought the 10mm x 18mm , his the cable behind the flex and then pushed the flex in flush to channel . Worked perfectly. However. The 10mm x 10mm is not quite deep enough once you put screws in it . It pushes flex out a bit . And also comes with no holes . So DIY is not straight forward , but having said that im pleased with the whole outcome , ATOM lighting is pretty good at making things brighter , sorry about that
New garden LED strip edge lighting
Easy to install, maybe a bit more on the tails would be good.
Neon flex
Looks great used as an edge lighting both sides of gravel pathway and an uplight to new wall for split level patio and garden. Really good effect at night.
It just works!
Fantastic product, comes cut to size with waterproof caps preinstalled. Exactly what was needed for the job! Customer service was excellent!

Led neon dual bend
I have to say . The experts at ATOM , were extremely helpful regarding info about products , once track was up the strip sat in nice and neat . I had to cut it as was a tad long but I did it with a sharp knife no problem. I did however purchase a transformer from elsewhere and saved quite a bit , overall really pleased with the product, Brian

Good service
We bought two lengths of LED strips with power supply and WiFi controls, one was 6mm and one 10mm the 10mm had a fault and did not light across the full 9 meters only the first meter, these were replaced after a email and phone call, all working well now and no issues
Natural White 4000K COB LED Strip 24V 480LEDs/m IP20 FreeCut
Very happy with this LED strip. The 4000K natural white is exactly what I was after—bright, clean light without looking too cold or clinical. The COB design gives a continuous line of light with no visible LED dots, which makes it look much more professional. I installed it in an aluminium profile, which gives it a really neat finish and should help with heat dissipation over time. The FreeCut feature was useful as it meant I could get the exact length I needed without any hassle. Overall, it's easy to work with, gives off plenty of light, and feels like a quality product. I'd definitely use it again for future projects.
Excellent service from the AtomLED team
Excellent service from the AtomLED team and the product is absolutely perfect. It is flexible, strong durable and the diffusion is so good. Can’t wait to show you how I used it in a new product I’m launching soon. Really happy, thanks guys.
It was all dealt with very carefully and
My order was all dealt with very carefully and professionally
Simple to use multi channel faceplate.
Takes a little time to check and setup but worked with their CCt controllers straight away. Simple to use and adjust light settings which was one of the reasons to stick with white. As for longevity, not sure if the unit holds last settings if the batteries need changing. We'll see.
Incredibly helpful team
Thanks.
