Hi. I'm going to make my tank into more of a biotope tank and i need the figure out what sort of lighting to get. Now it sits with two t8 fluorescent lights but the light is far to bright for my idea. I want really subdued lighting with a spotlight effect. This is what i'm looking for or having 2-3 spots in the tank : The light used in tank in the image is Beamswork 48" But looking at it it's not easy to get a hold of one. i can order from ebay but it will take anywhere from 5-12 months to arrive. What i need to figure out is what sort of strenght i need if it's lumen or watt or what ever so i can look for some led lights that i can diy some fixture for the tank. The tank is 45cm or 17.71653543 high. If i were to go for the lumen on the lights the image above has, it's 54x - 2500 lumen is it 2500 lumen per light or is it 2500 lumen combined? Then i also don't know if the tank above is 18" high or 24" high, it being a 135 gallon. Here is my nano light Boyu CL-2L3 1.5w on the tank i want to figure out the lighting. This would work if i could figure out a good way to attach it. As you might see it has a black aluminum border around it same on the top so no were to attach this light + the light is quite expensive about 20$ a piece and i would need 3 of them. I can probably find some normal lights in a hardware store that does the same job for the same as one of those lights and will probably be easy to attach to the wall or the ceiling. Do anyone have any idea what to look for to find the right "bulbs" for the job?
