First purchase of this type of lamp. This diode configuration makes the bulb bright enough, but it's not directional light. The light comes from the side, so they appear less bright in front of the lampshade, but brighter 360 degrees around the bulb. They illuminate a small space very well when using a bulb. Ideal for floor lamps. They are easy to install in a standard socket. I haven't noticed any heat issues either. They look good and have no trouble with all of them working. The plastic on the diodes makes them safe and durable if you drop them. Very easy. I only installed them in outdoor lighting. My light bulbs are cool white. Haven't used them for long so can't comment on how long they last but they look very nice. The packaging is a small box, but the plastic is strong so it didn't break during transport.
