Garden lighting - Solar or Wired?

Asked the same question probably 8 years ago and ended up going wired. I did go LED and have only changed a few bulbs and one light over the years (kids basketball). The solars go out pretty quick and some will be dimmer than others. Do it right the first time.

Just remember if you go with solar that you'll be replacing the lithium batteries in each light every two years. $$

Even doing that won't give you dusk to dawn lighting, if that was your plan.

Malibu Lighting used to be the top of the line for LV outdoor lighting but I think they've gone out of business or at least don't offer the variety of lights they use to. It's been 8 years or so since I installed them at my SO's house.

I used solar powered years ago and after a about a year they look cheap and you get What you paid for. Wired all day long.

Dont go solar. You get what you pay for. Wired works much better, looks much better, and will last much longer.

As for recommended brand, I bought volt through costco and any extra spotlights i needed where you couldn't see the fixture I bought on amazon.

I just ran 125' of LV wire and installed 9 LV LED lights in my front landscape. Bought the lights and transformer from Amazon. Had solar originally, but I wanted all-night light.
Had the same issue as OP regarding a walkway. Luckily there is an expansion joint right where I needed the wire to run, just had to open the joint up. Used a grinder with a concrete wheel. You could also use a circular saw with a concrete blade. Once I had the wire in the gap, I used self-leveling sealant to fill the gap. Connect lights to LV wire and done. Not difficult at all.

And spread ant killer around each light at least twice a year. They'll build mounds around them looking for warmth and it'll wreck havoc on your fixtures.
