Review on Industrial Electrical Plug: Decorative AC100-240V, Non-Dimmable, Non-Portable Connection by David Kits

We use 9 of these in a lamp, they give very little light. We like the looks, but it's essentially useless as a light source if that's what you're expecting. Since it's an incandescent bulb, it probably needs to be a little brighter. Also, the glue on one of our lightbulbs came loose, I'm glad it happened before we put it in as it would have shattered all over our glass table underneath. Aside from the quality control and the fact that they don't emit any light, I would recommend them for decoration.
