There are two things that really impressed me about this grow lamp: 1. Wires are neatly hidden in the light post - This gives a very clean look to the light. However, nothing is perfect. You have to mind the wires as you adjust the lamp up or down. Not a problem, you just have to be aware of it. And it puts the controller down on the floor. Again, not really a problem - I have mine set to 4 hours/day, so I don't have to touch the controller, it's on automatic. I should add that there are 2 connectors inside the light post - they are quite tight, so that's good, but do be a little careful when adjusting the height - if it does not move easily, check the wiring to see if that's the issue. 2. Highly adjustable - this is a great feature! We all have different size plants that we are providing light to and our plants will change in height over time. This light has two different ways to adjust: 1. Use 1, 2, or all 3 of the post sections. Check out the picture from the listing that I attached. You'll see that in the lowest position, 31.2" high, only the section with the LED head is attached directly to the base. If you add another section, you will add 16" of height, and with the third section, another 16". 2. Use the adjustment that is part of the section with the LED head. That provides about 13" of adjustment. Really nice light - you can cover anywhere from the 31.2" to 63" all with this one lamp. 5 Stars for this nicely designed and well made light. ================================================================== Couple of extra things - * In looking at the other reviews, one person mentioned that there was a "lens" loose in the box. That does indeed snap into the LED head to protect the LED's. On mine, it was not snapped in all the way, I just gave it a little push and it locked in. * I was impressed with the base, it's heavy enough so that the light doesn't not feel "tippy". And it has 4 cushioned feet that will protect your floor and provide the space needed for the wire to run out under.
