230 volts in 50 herz. 12 volt 4.9 amps max out. 3 x 20 watt halogen lamps in the kit so i know it will run those but need 4 lights. do i need another transformer to run the 4th light?

No. The circuit is designed to run three and to add the fourth without upgrading to reduce the risk of fire is not a good idea.

If you run one 50W bulb for 20 hours it uses one kWh of electricity. Look at your electric bill and you will see what you pay per kWh for your electricity. It's up to you to decide if that is expensive or not. You could probably get the same amount of light from 12W compact fluorescent bulbs - for 1/4 as much money per hour to run them. But the light would be of a different quality. Some people don't mind fluorescent and some really hate it. MR16 bulbs have a special connector and you can't just change the bulbs to compact fluorescent, you'd have to replace the light itself - easy if they are track lights, really difficult if they are recessed cans. Either the electric cost savings would take many years to pay for the new light fixture. Here in California where the law requires kitchens to be lighted with fluorescent, many people don't get building permits and hide from building inspectors just so that they can use halogen lighting in their kitchens.

Just get 1 x 105 va transformer, it will be ok with up to 5 x 20 watt lamps. The one that you have will have a very short life!!

They will run but the transformer will run a bit hotter
due to extra load, for how long it will last
is anyones guess.

it will burn 4,but they will be dimmer any more and you will need to upgrade to a higher amperage 12v transformer. just be sure the bulbs are 12 volt bulbs

12v x 4.9amps = about 60watts, so they would run at about 15watts per lamp, (a bit dimmer)

it may work.. with reduced power
the current application is actually slightly below the theoretical demand of the lights
your lights draw 60watts
your power supply provides 58.8Watts
Watts = voltage x amps
