Low Voltage Landscape Lighting


I have eight low voltage landscape lights, three path lights down each side of the driveway with a post light at the end of the drive. One side was dimmer than the other, and I suspected it was because of the run the wire had to make to get to the other side of the driveway. So, a second transformer was installed to power the far side. Still not quite equal. The path lights are now in fairly rough shape and we are planning to replace them. My thought was that buying LED path lights would use less energy, therefore not causing either side to dim due to lack of power at the end of the run. Am I right to think this might help? Also, I already cut the original transformer's load in half, since it was initially intended to power all eight lights. Now I'm significantly cutting the power needed from the transformer again down to four small LED lights drawing only 1.5 watts each (maybe a couple more watts in the post light if i can find a way to retrofit it). And the new transformer would also have this small load as well. Will this small of a load cause any issues? Thanks!!

None what so ever.....a very wise move.

Additionally, those LED lights will last a LOT longer.

If your looking for LED lights, may I suggest SuperBrightLED as a source for all types (including hard to find) LED's?

Your thinking is perfect...the LED lights will cause less voltage drop and you can run more on the lines. One bit of advice though is to get voltage regulated transformers. LED lights don't take too kindly to over-voltage conditions and spikes and such. They will burn out quickly if they don't get clean power.

Sounds good, and thanks for the replies! I thought I heard somewhere that significantly under loading a transformer could be bad or unsafe, but I might have misunderstood since I'm not super knowledgeable in that area!

Your problem was most likely caused by -
1 - a bad connecttion somewhere,
2 - a faulty cable run.
3 - Wrong size cable.

Remember at low voltage, it only takes a little
extra resistance (bad join) and you can lose a
lot of power.

Check and double check all joints and cables.

I'm guessing the problem was just a poorly designed wiring layout, you have to take extra care with voltage drop when it comes to low voltage landscape lights.
