Just how dim can light be for Java Fern / anubias?

[Paullywolly]

How low can tank lighting be for java fern and anubias to do well? I have 3x xenon lights over a 75g long. Seems like it should be enough, but any thoughts?

Thanks

its not really how dim but the amount of watts and the spectrum of those watts.. Those plants would do best with atleast 1wpg in the 6700K rating

I have seen monster java ferns growing with no light on the tank, and the tank is even on the bottom of the tank rack.

Growing, it had new starts coming off the leaves. He said it just grows slow.

Personally I havent had much growth with java ferns under 1 wpg, even in a couple months time. They are basically just there. At 1-1.5 wpg they seem to grow slowly. Over 1.5 is pretty decent growth. WPG figures based on fluorescent lighting mostly in the 6,000-12,000K range.

I've never heard anyone using xenon lights before, can you describe your lights in a little more detail?
