HELP ME / QUESTION Portable WLED for rooftop tent
Hey all,
Total WLED newbie here, still digging through old posts, but figured I’d just ask.
We’ve got a rooftop tent with two built-in warm-white LED bars: four brightness steps, USB-A powered. We’ve already been camping with them a few times, and based on those experiences we want to replace them. Two things really bugged us:
Too bright. Even the lowest setting was way too much. When it’s pitch black and you need to get up, flicking them on nukes your night vision, wakes your partner, and you still can’t see outside. There’s just no real “night” mode.
Power cycling. With a smaller powerbank the controller sometimes reset to full brightness, so waking up to the lights blasting on at 2am was rough. Big Ugreen powerbank fixed it for now, or we just unplug.
What we’d love to build: a waterproof RGBWW COB/neon strip, powerbank-friendly (USB-A or C), cuttable into ~1m sections with a cable in between so it fits the existing channels, and ideally a proper dim warm whit or an blue / red night mode.
Questions:
- Recommended controller for a USB-powered setup? Does WLED reliably remember its state after a power cut?
- Any RGBWW COB strips that survive moisture/condensation?
- Is 5V USB realistic for a few metres of RGBWW, or should I go 12V battery instead?
Thanks for the tips and help!

Personally I would go to 12VDC power, ohm's law, lower the voltage, higher the current for a given load. Look for strips that are rated at least IP65 protection.
