Easy install and seems to work well
Took me 5 minutes to install above the furnace, where the air passes through a large box before being divided into the various ducts.  Just used a metal blade on my rotozip to cut out the sheet metal, then the self-drilling sheet metal screws attached it quickly and covered up my jagged hole.<br /><br />Plugged it in to the outlet for the furnace, and it immediately worked.  If a bulb ever dies, it will only take a couple minutes to swap out.<br /><br />I was looking for easy, for our vacation rental cabin as a COVID safety measure, and we got exactly what we wanted for a great price.  Been running it for a couple months with no problems.  I did notice a slight glow in a neighboring room, if you have a duct with a very short run, the light can reflect and make your vent glow.  Since it's not a direct light, there's no danger.
