Review on 🏭 Vintage Industrial Wall Lamp: Black Hardwire Swing Arm Sconces for Home Decor, Bedroom, Porch, Garage - 2 Pack by Emily Quintana

That's how I got it and although the bulb is in the photo I haven't given much thought to what it means. I have no other lamps of this type. If you use them with white light of any intensity, they will blind you when you see them in your line of sight. It took me too long to install so the rear window closed and I decided to use them as colored accent lights instead. Anyway I have a lot of smart devices in my home so I added some smart bulbs and when used with green/blue/purple etc at lower brightness they have an accent light value. The main light source for the area - be careful - maybe if they were over a reading chair or something and you only turned them on when you were seated and they shone down on you from above.
