We purchased inexpensive solar lights at Lowes. They are working fine and we can move them when we need to.

Another vote for hardwiring LED lights. Our Sylvester has grown 15 feet in 7 years so I think we made the right lighting choice. To be effective the lighting needs to be adjustable & as strong as possible to reach the heights the tree will grow. They grow faster than we were led to believe

Awesome light output on my Sylvester with 4 small LED lights and the solar panel can be outside and shrubs or flowers. Apuono solar spotlights 4-in-1 are on sale on Amazon.

The hard part for diy solution is to get a power source to plug in the transformer. You may need to get an electrician for that. They can perhaps tap into your post light and install a weather proof outlet box. Then you can plug in the transformer and run the low voltage wires to/from it. Most of the transformers have a light sensor to go on at night and off in morning.

Order a couple of solar light from Amazon Prime..if they don’t like the look, you have 30 days to return.

Michael,

Like dude, like get like American English lessons like now. You say you are like 61.

Appreciate the constructive criticism - you have a blessed day my friend.

All of the houses I have seen have GFCI protected outdoor receptacles installed. If you are lucky one of these will be in a suitable location. The bigger problem is typically getting across the driveway if needed. I found that using a power washer to clean out the stress cut, allows a #14 low voltage landscape cable to be installed in the stress cut. You MUST be very careful at the entrance and exit of the cable as landscapers tend to cut these wires with their string trimmers. I cannot count the number of times I had to repair wires in this location.
Having an outlet installed on the lamp post works great, make sure this is either a GFCI outlet or that the lamp post is protected by a GFCI. Make sure the weatherproof cover can be completely closed with the transformer plugged in. I believe there are special requirements for the mechanical connection of the new outlet box to the pole for weatherproofing also.

I have solar lights. Not too bad for the cost. The solar lights are not as bright as the wired LED lights. My solar lights have been installed now about 6 months and they are still working fine. It's all about how bright you want your landscape lighting to be.

How far down do you bury the wire? I would get a straight, flat shovel and make the line that way. Push it into the earth, wiggle it to make a V opening, drop the wire down and step on the V to join the earth together again. Much easier down here vs up north.

You can bury to whatever depth you want, I ran ours right next to the house foundation and down about 2 inches to the weedwhackers would not hit the wires. In the garden landscaping, I tend to be an inch or so below the top of the stones or mulch.
IMHO, burying the wire in the lawn is the hard part, this grass is much harder to cut through.

On the driveway side, I will use a very small transformer and get power from the GFI near the A/C. Some might call this overkill for 1 or 2 lights, but in reality.. it isn't.

With the time it takes to run a wire thru a crack that will be exposed to sun and often cleaning chemicals and eventually shorting out ... the 50 bucks for a small transformer makes my install virtually trouble free. And I don't need to break out a concrete saw to clean out or widen those cuts in the driveway when the wire won't fit.

And never EVER put the gfi on your lightpost. Along with the problem that your garage fridge is likely on the same breaker, and a little problem kicking the GFI can turn into a freezer full of rotten food you were saving ....... You will still need to mount the transformer somewhere (on the post right?) and if mounted to code, it will be unsightly in the front, and breaking the protective coatings and paint on those posts, causing them to corrode and need replaced in just a couple years.

i got a cheap solar lamp from amazon about 3 years ago & it's still out there working!! when you shop, choose the 'customer reviews' option

why so mean?
