50VA - 300va Transformer for Low Voltage Lamps

Could I use this transformer on a Wire Track system
This would work with a tension wire lighting track under 4 metres in length. Beyond that you would be better of with a tradional wire wound or magnetic transformer. You may encounter issues when dimming a standard electronic transformer connected to a wire track. If you have 6mm cable they may not fit this transformer.

Hi there. I have 4 (may cut down to 3) 50w lights running on a single pair of cables, one after another on two wires, in a Parallel circuit. Would this transformer be suitable?
The minimum load of this transformer is 80w so your installation wattage is within the range required. All domestic transformers are designed to be used with parallel wiring. If this was connected to a lighting circuit wired in series all the lamps would be dim.

How far will this cover without a voltage drop? I need a transformer for 4 x 50w spots on a stretch about 5metres long. From the transformer to the lights do I need special cable or is normal mains cable okay?
Voltage drop is only caused the size of the cable and the length of the run. The thicker your cable the lower the drop. So if you`ve a little cooker flex to hand it will have less volt drop than 2.5 twin and earth flex - which in turn would work better than some bell wire.
