I’m planning to buy a 660–670nm red LED strip, DC12V, 120 LEDs/m, 5 meters per roll, mainly for plant lighting or red light applications.

What size power supply should I use for this strip?
Would a 12V constant voltage power supply be the right choice? How many watts would be suitable?

Hello, thank you for your inquiry.

For the 660–670nm DC12V Red LED Strip Light, 120 LEDs/m, 5 meters, we recommend using a DC12V 150W constant voltage power supply to ensure stable operation.

If the installation environment requires waterproof protection, we recommend the following waterproof power supply:

If waterproof protection is not required, such as for indoor or dry-location installation, you may choose the following non-waterproof slim switching power supply:

Please select the 12V 150W version on the product page. Since you are located in Italy, we also recommend choosing the suitable EU plug or wiring option if available.

For further confirmation, you may also share your installation environment or wiring requirements, and we will be happy to provide a more suitable recommendation.

For a 120 LEDs/m, 5-meter strip, the power draw is probably not very low. I’d go with a 12V constant voltage power supply and follow the seller’s recommended wattage to be safe.

If you’re using it for plant lighting or keeping it on for long periods, I’d choose a better-quality power supply and avoid running it too close to its limit. It should be more stable over time.

I’ve used a similar 12V red LED strip before. It’s better to check the total wattage of the full roll and choose a power supply with some extra headroom instead of matching it exactly.

For a 5-meter strip like this, I wouldn’t use a power supply that’s too small. It may get hot or cause unstable brightness. A slightly higher wattage would be safer.
