These lights work well because they bubble nicely but are so bright they outshine other tree lights. They almost look like headlights. The lamp at the bottom of each light is very large and must be of high wattage. I also bought colored bubbles and they aren't as bright because of the colored plastic caps. They seem to have the same "brightness" as the other colored lights on my tree. In addition, one of the sockets is defective and the light goes on and off. When I tighten the bulb it goes out. It needs to be left a little loose to work properly, which is probably unsafe. Overall I would not recommend this product.
