No those are incandescent lights. I purchase these lights through a wholesaler vendor focused on the Christmas Light industry. However, you can try your local Lowes or Home Depot to find Icicle Lights on the House. The lights on the trees are also purchased through the same company but you should be able to find similar lights at your big box stores.

Make SURE that you purchase commercial grade lights as they last longer and will stay lit even if a bulb goes out. I am not a huge fan of LED lights because they aren't as bright or vibrant as incandescent. That being said you can string about 10 times the amount of lights on trees that you can with the alternative.

Regarding keeping the lights up all year around on the trees I wouldn't suggest it as all the commercial grade lights that I use and the on.es for sale are considered temporary. I do deal with more permanent lights but not for trees. Mainly for patios. I would suggest doing a Google search for "Permanent Tree lighting" and see what pops up. .

Thank you so much for this information.

You are very welcome and have fun
