How do I get my low voltage landscape lights to be the same brightness?

They become progressively more dim the farther away from the power transformer they are (which is powerful at 300W).

1. They are probably halogens, not low voltage. The further away they are from the transformer, the more power they lose.
2. Double the wire size
3. Spent weeks reviewing the landscape lighting area in prep for a job interview related to the topic. Found this web site has great answers http://www.lowvolt.org/ Good Luck. Wire size and quality of connections as well as design. Loop the zone if you can.
4. First off, it depends on how far of a run you have. If it is long try using 10 guage wire. With low voltage lighting you will always experience some degree of voltage drop after each fixture. The lower guage wire will be able to carry more current to the furthest light and reduce the amount of voltage drop. Second, make sure you did your math right with how much load you have on the line. Some lights draw only 12 volts while others draw up to 35. Check to see that you did not go over the 300 max. Third, make sure you first fixture coming off the transformer has a minimum of ten feet of wire between it and the transformer. There a some transformers which compensate for longer runs, they will have multiple connectors for various voltage outputs (ie. 13,14,15 volts). If yours has this you can try to move your line to one of these. Or you can run a second line to reduce the amount of fixtures. Your best bet is to buy a better transformer. Stay away from the Home store ones, as they do not last long and the warranty sucks.
