Is this enough light?

[Nothing]

I have a 37g tall tank that is planted with a few cabombas and anubias right now, but I will be planting it more heavily soon. Right now I have an (I think) 20w Aqueon single light that came with the tank, and the plants seem to be doing fine, and I just picked up a Marineland Single Bright LED system to supplement. Is this enough light for all plants or do I need to take the Marineland thing back and get something stronger?

Is it meant for plants? Do you know the kelvin rating?

 

[Nothing]

It doesn't say it's meant for plants, and I can't find the kelvin rating anywhere

 

[Nothing]

But I just turned off the main light and this one seems pretty weak

Well if it's LED than watts won't give you any sort of help at determining power. Sorry, I don't know what to tell you. The kelvin rating is one of the most important parts of determining the "power" of a light.

That lighting is very low light even combined with the other stock LED. Plus you have a deep tank so honestly if you want an LED in a deep tank you should check out these by Build My Led... Freshwater - Build My LED, LLC. They are specifically made for planted tanks and you can get a 75% beam angle to help penetrate deeper into the tank like I did. I have 4 of these fixtures on various sized tanks and they work great. You can also get a dimmer attachment and use the light from 10% to 100%. I use the 10% after running the tanks at 100% for 6 hours.
