Power Supply

DC power supply is not same as ballast!!! Of course, DC power supply is not the same as ac power supply. Pay extra attention to the label for ac or dc output.

So a DC power supply saying that it's 400W will not burn your array of LEDs that use 10W if the voltages of the power supply and the LEDs are matching. However, if the output voltage(V) of the DC power supply is of higher voltage(V), then your array of LED will be running more current and thus your LEDS are running over 10W and burn. In another word, if your DC adapter says its 12V regulated
and your array of LED says the input voltage to be 12V, then you are good to go. Don't worry about the wattage.

If your array says it uses 10W of power while your DC adpater can only supply 4W of energy, the adapter will heat up and burn. This could be dangerous when your adapter started to melt, poisonuous gas, sparks and cause all hells to break loose.
