Hi All,
I'm a bit of a newbie to the planted aquarium scene, I've recently read numerous articles and watched many YouTube videos on lighting as i am intending to create something myself with either CFL or LED (6500k).
When it comes to Watts per Gallon/Litre it seems common that a Medium to High lit tank should be in the region of 2-4 Watts per gallon (according to my research, please correct me if this is wrong). However, no one has stated whether this is the input/usage value of the light or the output value of the light.
I have a 30 (ish) gallon (140 litres) tank and was looking at lighting it with 2 x 30W LED flood lights, totalling 60 Watts (@ 2 Watts/Gallon). However, the LED's state they are the equivalent output of 100W each... So would this therefore be miles to much light? I have uploaded an image of the sort of lights i was looking at...
The 30W LED floodlights i saw in one video, looked to be giving out enough light and can only presume this was the usage/input value that he gave.
Any advice from some lighting gurus would be much appreciated
Thanks
James
