Hi,
The only problem I can see is that your LED modules will
have to produce the same light intensity. This is going to be
important when the LED modules are mounted close to each
other and...

The power MOSFET IRLR/U2905 has logic-level gate drive and
therefore you don’t have to worry about that. Just try and
measure the voltage drop.
Hi,
From the datasheet. The thermal resistance junction-to-ambient is for when
there is no heatsink.
