These: https://amzn.to/3FoGFQQ which I have mounted in my 20x20 dog pen. They light the whole thing up brightly, and I've tested them after about 11 hours and they were still bright. I also have these on my fence lining my driveway. https://amzn.to/3tskRRQ
One of the great features of Picasa Web was that you could embed a Flash slideshow of your albums. Google would even give you the code to do it. There was a button that said Embed and it would give you the code. Just cut and paste and you were done. With the migration to Google Plus Photos, this disappeared. Here's a work around. Use the following link to get back to the original PicasaWeb site. https://picasaweb.google.com/ lh/myphotos?noredirect=1 Hopefully the embed button makes a re-appearance, or Google leaves the old page up forever. *******UPDATE******* One of the commenters below posted this website. http://www.slidemypics.com/ It seems to work pretty good!
