Read the product description carefully to ensure you do not expect it to work in a situation for which it was not designed. They will not work properly if placed too close together. If you place them the right distance apart they work very well and provide a significant amount of light. I only use one bulb in each of my two porch lights, which are rated for three bulbs each and seem to put out as much light as the previous six bulb configuration. A good product.
