Has anyone use(d) LED floodlights above a low tech tank with good results?
I am thinking of getting a few for my 120 cm tank, but I have no idea if they would be any good and which one I should get (2 x 20 Watt....or 2 x 100 Watt....) LED is still a on known light for me.

I run a large marine tank and use them over my sump for growing Chaetomorpha for nutrient removal. The cool white or 6500C versions work very well, ugly as sin but cheap enough. My sump compartment is 20" square, in the past I used a 50W and it grew very well, now I use a 20W (to reduce heat in the cabinet) and it doesn't grow as well as it did but still grows. If heat wasn't a problem I would go with the bigger lamp again
 
Roy our Greenfinger :) is using floodlights above his tanks, seeing his journals says enough. Tho it's not above a 120cm tank, which i think probably is 50cm height?? I'm using diferent kinds of leds above my 3 tanks at the time, anything 40 cm and bellow i'm pretty confident they are sufficient.. If it'll work for higher tanks i'm not realy that sure, probably never will find out since i'm not planning to build be anything bigger/higher than 40 cm. All depends also on the type of plants bellow it of course.

I didn't mean 120cm deep....maybe that wasn't clear of me...haha....my tank is 45 deep
 
I put two 90w led floodlights on a 29g tank yesterday to try them out. One is a spot light and one is a flood light. It is too soon for me to relate how well they work but I do like the light penetration. I did start with one but added the second because one didn't light the whole tank well. fwiw.
 
I use an auto light over my 30 cube nano. It's 27w 60 degree lenses. Probably slightly too spotty for my preference. Gives a great shimmer tho. Can't complain at $12.99 delivered....

2 - 20w cool white on the sides and a 50w in the centerish. they are on a piece of hard plastic but i need something better. it blocks too much light.

The 20w look slim where you get them
 
Any links for that slim looking 20W?

Tanks are looking good!
