There are effective cheap LED units and non effective unit. The picture you posted is a pretty terrible unit as it runs many many very small diodes which have terrible penetration. The LED flood lights use arrays consisting of 1w diodes and work pretty well for the price. Cheap units specifically created for aquariums with >1w diodes also work pretty well, ie Beamswork.
