Sorry all for the absence! Things have been very crazy for me lately.
Comment to SuperAaron: Be careful with straight AC-DC circuits. The LEDs are current based devices and characteristics change with temperature. If you do not control current, you may find that they are dimmer when cold and may run-away as they heat up. The driver is not all that expensive that I would risk the LED on a VR circuit.
Not So!! The LED is a constant-current device. The resistance will change with temperature and a constant voltage source will either provide very low efficiency at cold temperatures, or blow the LED when it gets hot. Please be careful!
you don't want to do tha.!!t. i did that and it bleach my color it has to mush light in one spot you need to spread that light ... 5x 20w is mush better because you are spreading tha light apart , but if it work for you let me know i had to do tha 5x 20w in order to work and my tank is 30'' deep

Another youtube vid where an american-sounding voice is talking about SODDERING. Sounds a bit rude to me. The word is SOL DER ING. With an L.

hello i have a question so can i plug my 30 X 3 watt high power led to my 100 watt driver without resistor??

so do you have to get the special type of led lights or does it just have to be a bright led?

o and the driver is just a ac dc two 12v and you can use a Voltage regulator
check this out Voltage regulator tutorial & USB gadget charger circuit
it a lot cheaper
