Now a days there seem to be a lot of LED lighting choices on the market from cheap to expensive, with usually cheaper ones just just working with basic on or off functions, while the expensive units may have light control settings to replicate sunrise to sunset...
As mentioned though, its all about finding the right type of lights for your setup, since some are rated to have high light levels, while some are only really good for low - medium light planted tanks... also the spread of light is also something you should consider as well...
