Designed with the ability to twist and turn at the joints without conflict to the wiring, these industrial lamps are not only beautiful but also highly practical. Originally designed in 1950 as the "indestructible" standard for work lamps, Jielde lamps are now the perfect modern accent for any room. The loft series is Jielde's industrial strength line based on the very first lamps ever created. Fully adjustable at each joint. All Jielde lights are custom painted with a high gloss finish and then given a unique serial number to identify the lamp. 100 watt max E26 incandescent bulb. UL Listed. On/Off Switch.
