Thank you so much, Randi Bain.

Wow, I was impressed with the light output. I've learned to take 'lumens" with a grain of salt, but that light looks pretty sweet. I like that the company claims 5 year life span too, that is realistic; unlike most companies that claim 40,000 hours or some such nonsense.

LED street lights are a well established technology. You should have no issues, with the exception of solar cell occlusion due to dirt and in you case, pine needles. So, expect to need to clean it, including pine tar. Now, to comment on your installation. I would recommend that if you do this a second time, that since you have a second person, get a rope, and bucket for your tools Have your person down below put tools in the bucket for you to haul up using the rope after you get up there with the other end of the rope. Have her tie your street light fixture to the rope so you can haul it up first and loose fit it to your extension arm. Then drop the rope and have her attach the rope to the tool bucket. This will be easier for you and allow a safer ladder climb. I also would recommend that once you put the ladder up you also take a strap or rope up to tie it to the tree so it won't move while you work. (In commercial work OHSA would require that the employee have other safety equipment to arrest a fall. But, you are not doing this as an employee.)

The link to langy does not work😢

How long do you think this will last before it doesn’t work anymore? Made in China I assume?
