Lamp a little larger, more stable, more powerful and aesthetic than 10 bean-shaped LEDs from the same seller but 22 LEDs and lower autonomy. The "bean" I bought more than a dozen (of all colors) for small children of my knowledge and all still functioning after one year; it more adult taste is more like small lamp (five centimeter more of the rod would have been desirable to read an entire page of a newspaper) office or to perfectly illuminate a dark corner, a closet because it is very stable on its wide basis. These two kinds of lamps are powered via USB or on a computer or AC with a mini transformer, not included, sold by Amazon.com In summary very pleased to have purchased many reliable lamps for cheap, this innovative home seller because I do not find any equivalent in Belgium.
