Question: Does the lamp neck bend over backwards? So it can be aimed at the ceiling for indirect light?
Document: This is a great lamp. Comes with an extra bulb, which is a plus. It casts a nice, natural spectrum light and the flexible neck allows me to position light exactly where I need it The natural spectrum light helps colors look true, which is extremely helpful when crafting.My only complaint is that the screw that attaches the base to the pole was missing. Reading other reviews I see others have had this problem as well. I searched everywhere ... it was not in the packaging.
Meanwhile, you're dealing with the top (where the light and flexible neck are) flopping all over the place. Then to get the whole thing seated in the base, you have to set it down on the floor (more flopping issues!) and THEN re-screw the two poles together, hanging on for dear life to all the separated pieces and praying everything is going to line up!
This lamp takes up very little floor space, and with the flexible neck, one can get the appropriate angle for reading so easily. Bulbs seem to last a long time, and a lot cheaper than incandescent bulbs. Easy to assemble. The set screw that goes in the bottom of the pole is scotch-taped in the package. Make sure you see it, and don't throw the packing materials away before you do!
We live in rainy Washington State and came from sunny Utah so we had some adjusting to do! Somehow turning on these sunlight lamps in my home office makes me feel more productive and cheery. The flexible neck makes it handy to use at my desk but with the stand, you could easily put this alongside a couch.
Great desk lamp and the pure white light is good for reading. Really like the white color for this lamp too.
This lamp is great for reading and hand sewing. Adjustable and light weight. Attractive and priced right. Would highly recommend.
I like the function of this lamp. It is designed so that it fits in a small area and the light can be  focused right where it's needed.Perfect for reading, sewing and hobbies.
Brought two of them. Wife in sun room and me in the living room. Best lamp I have ever had. nice that company put in extra light.
I ordered this light for crafting so I could have a much better light when working with crafts. It is a sturdy lamp but being very tall I wish I had ordered the floor model,
nice bright white light. easy to assemble. great light for reading or doing craft projects. bought it for my husband who was having trouble reading the paper with the normal lamp we had. This one works perfect
