Although the description and pictures clearly state 5W = 40W, the actual condition of the box/packaging is 5W = 60 W. Combined into an outdoor lamp with 3-4 bulbs, it shines very brightly. There are other 40 watt bulbs from dusk to dawn and they have the perfect brightness. They work and look good but they are a lot brighter than the 40w as stated in the online description.
