I have a bit of macro algae in the fuge area at the back of my biocube. I've been using a cheesy white led that came from another small setup for quite a while now. Not much growth on the algae really. I have been reading up on fuge lighting and looking on Ebay. I was wondering if one of THESE would do the trick? I don't need much light as it's a very small area. The one in the link above has a 60 degree beam angle. There's also THIS one that's half the price and it has 30-45 degree beam angle. Any idea if either of these would be suitable and if so which one would be better for my setup? For the price I'm leaning towards the 60 degree unless it's not necessary.
