Question: Is the "shade" part of this lamp made out of metal or plastic?
Document: Nice sturdy lamp. the flexible part, base and top part seem to be made of quality material. Great price .
This lamp is black on top and bottom with a silver gooseneck and a weighted base. It seems well made and takes a standard 60 watt bulb. The switch is on top of the light and feels fine. It is all metal and seems sturdy. I like it.
this is the perfect lamp if you don't have a lot of space.Best part of it.. its super-flexible. Great Priceand Great product!
This is a sturdy, all metal lamp. The biggest factor for me was that it is rated up to a 60W bulb where most desk lamps are only rated for 40W. This lamp works great.
For the price, these are excellent. Well built, flexible, perfect for all kinds of uses. You can put a 23W big curly bulb in it, and bounce it off the ceiling to light half a room. Yes, part of the bulb sticks out, but you can twist the lamp head to hide it... I bought another!
Pros:- cheap- provides light when requiredCons:- tips over very easily- entire top of the lamp gets blisteringly hot (especially bad with the tipping over easily thing)- the only on/off switch is a tiny knob set into a metal base on the top of the lamp.
The product has a great value, and it works very well. I feel I made the best choice! Cheap, nice and helpful.
Don't waste your money!!!!!!!!!! This thing can't stand up on it's own because it's so top heavy and the bendy metal thing barely bends and honestly you'od be better off with a bare light bulb.
Although it appeared nice at first, it is starting to have a chemical smell to it (like burning plastic). Buy a better quality product.
this lamp is so efficient, and it does not take up a lot of space. i just love it!
