12V LED Driver
A 12V LED driver converts mains 230V AC to safe 12V DC output for powering LED strip lights, neon flex, and puck lights. 12V is the standard voltage for vehicle, caravan, boat, and battery-powered LED installations. For new fixed installations in homes and commercial spaces, consider 24V or 48V drivers which offer lower voltage drop on longer runs.

When should you choose a 12V driver over 24V or 48V?
Choose 12V when your LED strip is specifically rated for 12V operation, when the installation runs from a 12V battery (motorhomes, caravans, boats, solar systems), or when you are matching existing 12V infrastructure. For new mains-powered fixed installations, 24V or 48V is preferred as they deliver the same brightness with lower current draw and less voltage drop.
How do you calculate the right 12V driver wattage?
Multiply your strip wattage per metre by the total length in metres, then add 20 percent headroom. A 3-metre run of 9.6W/m strip draws 28.8W — select a minimum 35W driver. Never run a driver at more than 80 percent of its rated capacity.
What is the maximum run length on 12V?
12V strip has the highest voltage drop of any common LED voltage. Maximum recommended single-feed runs are typically 5 to 8 metres depending on wattage. Beyond this, visible brightness drop occurs at the far end. For runs over 5 metres, consider upgrading to 24V which doubles the run length, or 48V for runs up to 30 metres.
Frequently asked questions — 12V LED drivers
-
Can I use a 12V driver with 24V strip?
- No. The driver voltage must match the strip voltage exactly. A 12V driver on 24V strip will produce dim, unusable light. A 24V driver on 12V strip will destroy the LEDs.
-
Do I need a dimmable or non-dimmable 12V driver?
- For single-colour strip with a wall dimmer: TRIAC dimmable + trailing-edge dimmer. For RGB/RGBW: non-dimmable + dedicated controller. For no dimming: non-dimmable (simpler, cheaper).
-
Can I use a 12V driver in a caravan?
- If the caravan has mains hookup (230V), yes — the driver converts mains to 12V. If running from the leisure battery (already 12V), you do not need a driver — connect the strip directly to the battery via a fuse and switch.
-
Which IP rating for bathroom?
- IP67 minimum for the driver. Locate the driver outside bathroom wet zones. IP65 is not suitable for bathroom wet zones under BS7671.

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!
Perfect

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
Amazing service had a issue with one the strips

Superb product and great service ,had an issue
Superb product and great service ,had an issue with one of the LEDs , it was resolved immediately and sent out same day, highly reccomended
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.
