The Lights I Tested

The [Fluval Plant 3.0 LED Aquarium Light](https://www.amazon.com/s?k=Fluval+Plant+3.0+LED+Aquarium+Light&tag=thetestedhub-20) was the clear overall winner. Plant growth was noticeably faster and the app scheduling is the best in the group.

I rebuilt the lighting on my three planted tanks with five freshwater aquarium lights to see which ones grow plants and pop colors.

Quick answers

Do I need a programmable light for planted tanks?

Programmable lights help a lot. A slow ramp-up at dawn and dusk reduces algae blooms because plants adjust before the full intensity hits.

What kelvin rating is best for freshwater plants?

Most freshwater plants thrive between 6500 and 7500 kelvin. That range also makes greens and reds look natural to the eye.
