What kind of light is it and how big is your tank?

You can but for the sake of lighting up the tank. Won't do good for the plant. The spectrum in reef light differ from planted light.

Can I be able to used my reef light for planted tank? Or it is too much light? What you guy think.

I think you should read the lighting sticky. And peruse the web so you can learn what light plants for photosynthesis.

Meh,

I have DIY led lighting with multiple channels at different wavelengths. I can turn the whites and reds off leaving only the royal blues on (450ish nm) and make my plants pearl if i turn them up to 100%. Both plants and corals have chloraphyll. Sure there might be an optimal balance in spectrum and I doubt my plants would be happy with only 450nm for a long period of time(the fish were freaked out too) but it's not like plants won't grow from a reef light.

I think a 20k light over a planted tank would look terrible though. Especially red plants. A 10k light would be ok if there isnt too much PAR.

Some reef lights work perfectly fine for a fw planted tank. 10000k spectrum, crosses over into the reef world, will work great.

10,000k and actinic in a 1:2 ratio.. Plants grew fine.. Tank was ugly..

I don't think actinics look very good in a planted tank. Some people like them.
