I've only ever had led lights for our Christmas tree. That's....30, or almost 30, years now. We've never had a problem with them being too bright. But then again, with the amount of white garland and ornaments we load the tree down with, you can't really see the brightness of the lights. We can see that there are lights, of course, but nothing like we would if it was just the lights and nothing else. We load the tree with lights, too. Figure 150-200 lights a string, we usually put five strings of lights on. And the tree is only 4 feet tall. When we used to put up a full size tree, we'd put at least more than twice as many lights.
