Review on Simple Deluxe 12-Pack Clamp Lamp Light with 8.5 Inch Aluminum Reflector, 🔦 Up to 150W E26 Socket (Bulb Not Included), 6 Feet 18/2 SPT-2 Cord by Leslie Mayo

Well made lamps all around. The reflectors are threaded so you can remove them if you just want a flat socket or need to install a large umbrella. The clips are strong enough to hold the light steady when clipped to the 2" side of a 2x4 or something smaller - I used a pair of these clips clipped to the edge of a piece of sheet metal. The wing nuts tighten the pivot assembly. just enough for the simple shape to dangle - some of the cheap ones I've used just don't tighten. In general, an excellent work light that cannot be faulted.
