Ah yes. The math. Earlier in the thread I copied from your LED strip manufacturer's specs that it uses 8 Watts/meter.

Each meter contains 20 3-LED segments. So each 3-LED section uses 8W / 20 = 0.4 Watts per 3-LED section.

At 14V, your lamp-post bulbs nominally use 0.42 Watts...it will be lower when only driven at 12V so for back-of-envelope purposes let's just call it 0.4 Watts per incandescent bulb.

Whether it be harmonic convergence, divine intervention, or just dumb luck the power is about the same!

Your power source is capable of 9 Watts so it can drive 1 meter of strip LEDs. Hence I say mix-and-match (up to) 20 3-LED sections or incandescent lamp-post bulbs.
