Will my outdoor lights be dim if I use different wattge lamps on one 12 volt transformer?

I have a 600 watt transformer with 2 runs that can handle 300 watt's per run. Will I get the same brightness from the 5 50 watt lights and 6 50 watt lights? Anther way the ask the question is it better to install less than 300 watts per run to obtain the full brightness of the lights. A second question is does the distance from the transformer to the first lights make a difference on the brightness of the lights? We put our transformer in the basement and ran the wire for about 35 feet before the first set of lights.

You will experience VOLTAGE DROP the further the lights are from the power supply. The difference in light output between 250-watts and 300-watts on your runs will be very little. If you put the least amount of lights on the longest run you can overcome any significant loss of light output.
