text: So far, not impressed.
  
  My lamps arrived yesterday and I opened and set them up today. I ordered five of these lamps and have already noticed issues with a few of them. One has an arm that is so loose I can only use it clamped to a horizontal surface. If I clamp it to a vertical surface, the arm continues to droop far past where I want it to be. I tried to tighten the nut where it is attached to the clamp, but it wouldn’t budge. Another has an arm that droops towards the lamp end, but the fitting is tight, so it appears the flexible arm itself is just a bit weak. Lastly, a third lamp has flickered as I adjusted the direction of the bulb, the bulb is screwed all the way in too, so it is not loose in the socket. So far, I’m not impressed with these lamps but hope they serve my plants well and ultimately the lamps have a long life. I’ll update my review in a month or so, once I’ve had time to evaluate if they’re truly beneficial for my plants.
