low voltage lighting

[spikey mikey]

Hi

Apologies if this question has been answered elsewhere but I couldn't find what I wanted. I want to fit low voltage (12V) recessed spots in a new kitchen. I want to use 10 - 12 in the ceiling. Most kits seem to contain 2 or 4 lights.

Questions:

1) What is the opinion (of those that have them) on wattage for ceiling lamps? Some will be ceiling above w/top, some ceiling to floor, none under top cabinets.

2) What is the calculation to work out the (single) transformer needed for this number of lights?.....

3) ......Or do I have to buy (say) 3 sets of 4 (each with a transformer) and connect them in parralell to the original ceiling rose?

4) Any complications for two-way switching. The current light is two-way.

Thanks

Spikey

transformer = watts x number of lights

so 50w lamps x 10 = 500 w

also you would need to reinforce the ceiling to take the weight of a single transformer

get one transformer / light much easier

Best method is to use as many transformers as your budget will allow. One 50/60 va per 50w low volt fitting is best.

And stick to a decent branded one (IBL in my opinion is the best) for transformers
