You've seen imitations of this lamp just about everywhere, but that's what they are, imitations.
There's only one Verilux® Original Full spectrum Floor Lamp!

• This lamp is brighter, produces less glare and helps your eyes and mood better than those cheap imitations. You'll notice the difference instantly! 
• Now 20% brighter, the original Full Spectrum "indoor sunshine" lamp utilizes 50 years of research expertise to scientifically tune light for the eyes of readers, crafters and computer users. 
• Unlike imitations, only the Verilux® Original Full spectrum Floor Lamp includes the famous energy-saving Verilux® 27W bulb.
  • *These bulbs last 10X longer than incandescent bulbs (10,000 hours).*
• See fine details with ease as exclusive Verilux® technologies
  
  • optimize black-white contrast
  • reduce eyestrain-causing flicker and glare so you can work longer with less eyestrain
  • Verilux® full spectrum actually relaxes your eyes the more the lamp is used

Check out the other differences:

• the flexible gooseneck adjusts smoothly and quietly
• the exclusive Parabolic Light Diffuser totally eliminates glare from a bare bulb
• the three-way switch allows two levels of illumination
• offered in Graphite and Ivory finishes to match any decor

And the best indication of the difference between the knock-offs and the Verilux® Original Natural Spectrum® Floor Lamp is that the Verilux® is fully supported by a 3-year limited warranty.
