    Will a spotlight work in a nano tank?

    The tank is about 120l capacity, about 40cm deep. Would a single outdoor spotlight/floodlight with a 97% daylight 24W energy saver globe work for lighting? My idea is to setup a reef tank with minimal fish.

    Cheers
    Adam

    one watt of fluorescent to 4 litres of water. 10 000 kelvin

    Ok, cool. Will that be enough to keep some of the corals that need a lot of lighting as well?

    Besides that it won't be enough light, it will also look very yellow. Although 10000K is great for growth, it also looks too yellow to me. You will have to add some blue if you want well...a bluish look :p
    But that depends on what color you like

    Here is my reasoning: The idea is to have the best possible coral growth, and the best growth you will get with, well, natural sunlight. So why not replicate that?

    Have I got something here or have I just lost the plot..

    If you have enough wattage for the size tank, then yes, it will work....but it will look very yellow and will also encourage algae to grow if there are slight nutrients present, as they love lower kelvin ratings. If that doesn't bother you, go for it taking into account the wattage ;)

    Cool, thanks @Tobes, I'm going to set up a couple of lights and see what works for me.
