It's only 12 inch in diameter but gives off tons of lighting because it's LED. And for sure you don't need extra bulbs to make it work.Acrylic Dome The dome of the lamp is made of acrylic which has a good transparency for light to pass and eliminate those sharp lights that heart your eyes. It is very soft and definitely won't crack when you accidently drop it.NOTE Radar detection may go through windows/doors/walls, sometimes it's over sensitive so you better make sure it's big enough where you install it.
