All sounds confused. Use one transformer to supply the lot, and it will
need to be a toroidal, not an electronic one, since the tronics have
minimum load requirements that youll go below.

The toroidal transformer plugs in the mains, theres no reason to add a
CU way for it.

Switch everything on the LV side, switches wherever you want them.

To determine ratings of transformer we need the specs of the lights:
power, voltage and type. The kit says halogen, you say LED. Kit says
10w, you say 10v - proper info required.

Since everything will be wired at LV, life will be easy.

OK, I should've done this to start with... I've grabbed the boxes and
here are the relevant specs/ratings:

Kit Name: "2 Beam" (2 x 115mm dia lights containing 36 LED bulbs each)

Barcode: "5 014838 170038"
Model No.'s: 7002, 7003
(Info is not very clear as these are repackaged for B&Q)
NB: Having read instructions inside, these now tell me that
light fittings should ONLY be fitted in a VERTICAL position! But doesn't
specifically say NOT Horizontal, just that WET locations should be
avoided. No indication of this requirement on the box itself! I want to
mount them horizontally in the decking... should/shouldn't I? I could
use some 4" drainpipe to deter water ingress... yet more questions!

As mentioned before, I bought three of these kits, to give me the 6
lights I'm after. Leaving me with 1 redundant transformer and 4-gang
adaptor. I know there are accessory packs available containing just
lights, transformers etc, but you know B&Q... chaotic, understocked and
when you eventually find a staff member, they don't know jack!

According to the packaging and instructions, the kit includes:

1 x Internally rated, plugin transformer (12VDC 2000mA) + 15m cable
1 x External (IP44) 4-way JB (adaptor)
2 x External (IP44) light fittings + 5m cable

Kit Name: "10 Ultra" (10 x 15mm lights containing 1 LED bulb each)

According to the packaging and instructions, the kit includes:

1 x Internally rated, plugin transformer (12V 200mA) + 15m cable
* doesn't specify whether AC or DC!
1 x External (IP44) 10-way JB (adaptor)
10 x External (IP54) light fittings + 5m cable each

Kit Name: "Button" (4 x Post Spike lights with Night Sensor [optional])

According to the packaging and instructions, the kit includes:

1 x Indoor plug with 3AMP fuse
1 x External (IP64) Transformer (12VAC 4200mA) + 4m cable
1 x External (IP44) Photocell (night sensor) + 2m cable
1 x 14m extension cable
4 x External (IP44) spiked, Halogen lights

Kits 1 and 2 are from the same manufacturer. Kit 3 from another.

Can all these be powered by one transformer?
