This may sound like an odd question because of course I know what my lights are...I'm the one that bought them. But I just don't know how they are in terms of what level of light they are providing to the plants. People and informational sites speak in terms of strong light, moderate light, low light, etc. But I don't know where my lights fit into this as neither are standard aquarium lights.
I have the same bulb in both lights. They're GE CFL's 13W (60W equivalent), 825 lumen, 6500K.
The 2gal uses a clip on desk light, its about 6" from the tank and at an angle (probably about 45 degrees). Open top, light colored substrate, the light seems to penetrate evenly. I feel as if this light is probably on the bright side.
The 10gal uses a floor lamps' attached reading light. It is directly over the tank looking down, about 9"-10" from the surface of the water. Open top tank, tannin stained water, and black sand substrate. It seems to have a lot of shaded areas, as in it seems really bright at the top but there are a lot of poorly lit spots near the bottom.
Not sure if pictures help or not, but if so, here ya go.
The pics of the 10gal are pretty representative of how it looks to the eye, however the first one of the 2gal I feel makes it look darker than reality.
