We have been using yellow bulbs in our garden for a long time and we can safely say that they attract fewer insects than their alternatives. The downside to our previous yellow incandescent bulbs is that they gradually dim until they eventually go out. We do not expect such a problem with these LED lamps. Not only do these LED bulbs attract fewer mosquitoes, which are the bane of our existence, but they also use less energy and last much longer. These bulbs are just as bright as our previous incandescent bulbs, if not brighter. Overall we are very satisfied with this product.
