No Idea Of Watts

[mattyeatsmatts]

So I have a LED light unit that came with a 8L Nano tank. There is 16 diodes in the unit but im unsure if it is a high or low number of watts.

Made by LG, do you think I should contact them?

Anyone got a rough estimate of how many watts the unit might contain.

Thanks
