Every 12V RGB kit ships with a controller, remote or WiFi/Alexa option, and the driver sized for the run length.
6×12mm mini and 8×18mm standard bodies. IP65 indoor and IP67 outdoor options. WiFi controllers compatible with Alexa and Google Home, music-reactive controllers, and standard remote controllers. Run length capped at 5m by 12V voltage drop physics.
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).
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.

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.
Thanks.
Great high quality led looks great at night
Very happy with the purchase. Quality connectors and hassle-free setup.
I was searching for good quality LED rope lights and came across Atom. I ordered 50 mtrs reel of RGBW lights and the item was delivered very quickly and the after sales service has been second to none. Adam has very been helpful with my enquiries every time I have called and it's never to much for him to assist. I would definitely recommend buying from Atom and definitely will do again on my next project.
I ordered a specific lengths of ip68 warm white led neon strip for my drive. I installed it as I had installed my other led feature lighting from ATOM and the result was great. Delivered in less than 48hrs the strip was exactly the right length as I had specified. The quality is exceptional and easy to install. The end result justifies the investment and their prices are vey good. Can’t fault them and highly recommend. I will be back for more strip as I have further ideas around my house. Thanks Atom!
I ordered 2 controllers for a time-critical installation where I needed to confirm everything was working before completion. I placed the order and the items arrived early the next morning and in time for the installation to be completed! Very grateful for the swift response and attention.
Good LED strip for outdoor application and good advice from the Atom team. Thanks!
Great product expensive but really worth it
Warm White 3000K COB LED Strip 24V 480LEDs/m IP67 Waterproof 20m Run
LED controller recommended by their team and it is great with a auto fade in effect when powered and brightness which can be set
Good product but the clips/brackets do not secure properly. Bad designs and made installation tricky.
Looks great and very easy to install
Very good quality
Although it can be tricky to secure the string to the LED strip to pull through the tube. If all else fails cut the rear of the tube.
