Small Clip-on LED Aquarium Clamp Light RGBW

What is the best light spectrum for low-light level aquarium plants?
Plants in aquariums need all colors of the spectrum for food-making (photosynthesis). But using a red and blue light spectrum is better because it makes the colors pop in plants and gives them more color. That's why it's not recommended to use plain white lights in aquariums.

The clip-on light for the aquarium uses a special kind of high-quality light that makes the colors look better. It runs on low power, which is very safe and lasts a long time. The light comes with a flexible arm, so you can move it to the right spot. It also has a simple controller with three modes: white/green/red for daytime and blue for nighttime. This light is made especially for betta fish and plants that don't need a lot of light.
