My hubby has been thinking about turning a Chi into a SW tank for some time now. He is aware that evap will be an issue and has come up with the "hampster bottle" ATO to solve that issue. He is however looking at doing a DIY of LEDs over it for the lighting. He has done some research, but I need to know what is the difference between a 1w and a 3w LED? Is one stronger than the other? Will one last longer than the other? He's at work right now so I cant ask him.
