Nice one Weeze!!
Not safely.

Bad idea to use a 2A supply to supply 2A. continuously.
It will run hot, and fail early.

There's an adjustable 12V. 20 A. supply on ebay for $20 USD.
I had to slap a fan on it to keep it out of thermal shutdown for a constant 12 A. draw, but it is rock-steady with the fan.

Switching supplies are relatively cheap so best to go overboard on the powersupply for safety and future expansion of your array.

If you have the budget for it, (About $140 USD.),
I recommend getting a large constant voltage/constant current, digital readout, variable supply for building and bench-testing your lights.
If you only build the one light, you can use the bench supply to feed it, and you are done.
If you build more and better lights in the future you will know exactly what you need in a permanent supply by the readout on the bench supply.

You can find the bench supply by reading through

I can solder, but I'm no engineer, so, I'm asking for help in creating a circuit design that balances low cost, simplicity of construction and high efficiency.
