Can you tell me what the max that can be connected together at the moment I have 29 led deck lights with 3 separate transformers and they just fail so often its unreal, so I had hoped I could have 29 of these daisey chained from the mains so would be a lot easier to sort if one blows.
Daisy chain wiring is an often misunderstood phrase that should only be used to describe items wired in series. Often like a set of old Christmas tree lights if one lamp fails all the lamps stop working. These fixtures use a mains supply and like all mains lighting they should be wired in parallel. You could operate hundreds of thesecLED fixtures on a single 5 amp lighting circuit. Furthermore when wired in parallel if one fails all other lights will continue to work.

Is the LED bulb replaceable?
This is a non replaceable LED. Please not the LEDs are expected to last 30,000 hours and the fittings have a 2 year warranty.

Can 9 of these fittings be used controlled on one switch?
Yes your electrician should be able to wire these up to connect them all via one switch.

Are these lights suitable to be installed in a brick path where the bricks are porous to rainwater?
These are IP65 rated and would be fine to use in a outdoor path.

Would these lights be suitable for installing in a concrete ramp pathway we are about to get built and if not can you advise me what would be suitable.
Yes, these can be installed in a concrete ramp pathway.

do i need a driver to run these lights and how many can i have per driver?
These fittings run at 240v - so do not require an LED driver.
