what is the voltage requirment of the strips? how did you get 19.5V?

from what i can gather (correct me if i am wrong) you are trying to run

- 1 led bar that came with a power supply rated at 13.5V
- 2 led strips that are rated at 12v

The strips (rated at 3 watts each, don't know the voltage, has 4 lights per strip) can be connected (both) to a 12v power supply.

Sorry I miscalculated the vottage, 19.5v is wrong.

Here's what I know:

Fluval LED bar: 13.5v 1500ma
Current USA LED strips: 3 watts each (6 watts total). They say 1 - 3 of these strips can be connected to a 12v power supply through a splitter.
