I have just finished a brick & stone mailbox which added some glass blocks on the sides with 2 low voltage lightss inside.I have about a 200' span to wire for the lights.what wire should I use for this?Can the solid wire such as 14-2 be used for this?
Thanks for your reply

What is the wattage of each light?

I assume that you will want to have the transformer by the house and only run the low voltage power to the mailbox.

yes,I have 2 - 11 watt lights & a transformer for up to 200 watts.I could drop down to 4 or 7 watt bulbs if neccesary.
sorry for not getting back sooner-out of town.
thanks , grahmpa1

You can run the sranded low voltage cable or UF-cable. The UF cable is a romex like cable designed for underground usage.

The flex low voltage lighting cable will be much easier to handle than the solid UF cable.

However, running low voltage the currents are high and you have to watch for voltage drop.

For the 11 watt bulbs you would need to run #8 wire to get good results. But it might work with #10, but be a little dim.

I think that I would run #10 (if it is available in low voltage cable).

Then you an try the 11 watts, but it if does not look right then use the 7 watt.

Your other option would be #12 and try if the 7 watt and if it does not look right then use 4 watt.

Thanks Bill,sounds like I should do some experimenting before I trench it in.

Note: if you use standard #12 or #14 UF cable, that will still work fine if at some future time you replace these to regular 120V lights.
