    Hey guys, im new to this hobby. I hope someone can recommend me some lightset for a 44.4 x 26.6 x 25.5 cm (30 litres / 7.97 gallon) low tech non c02 tank.

    According to TomBarr method, 1.5 to 2w/gal is good thus i assume that my tank require at least 16 watts and wonder whether i should get T5 or FL light (what is the difference) ?

    And where i could get a nice 1.5 feet lightset?

    Well it depends if you are going for a high tech or low tech setup. For a tank that size 1.5 - 2 wpg would normally be for a low tech set up.

    Why? [QUOTE]Light is measure in lumens. How bright a light bulb is sort of related to the wattage it consume. Eg. 18 watt fl tube may produce a brightness of around 100 lumens (just a rough figure) and 36 watt may produce 150-200 lumens (just a rough figure). It depends on how the ballast is constructed as well.

    If 36w of bulb is use on a 5G(1x1x1ft) and 15g(2x1.5X1ft) tank, both have the relative height, same amount of lumens brightness will hit the base of the tank. But if you work out the wpg, will be 7wpg and 2.4wpg. As you can see, height determine the light bulb intensity as well. [QUOTE]

    Also some light it lost in smaller tanks so less light hits the plants.

    For the light set can try NA
