I had some concerns about a few things, just based on other LED products I've got. But this one has no LED issues and we're getting a few more for the office.
1: On max brightness this will light up an entire work surface. This new unit, with only 6 LEDs, is bright on max level. I'd say it's brighter a standard fluorescent desk light, and covers a larger area.
2: The Daylight White still looks like a high quality high Kelvin light source - it is not too "blue-ish" - I had been concerned about that based on cheaper led products.
3: On low brightness it does not have any flicker. As you may know, LEDs are usually dimmed by cycling them on and off, and as a result, many LED products have a high frequency flicker that I can usually see. I'm pretty sensitive to flicker, maybe due to my eye condition (albinism), and I can usually see the flicker in indirect tube TV light and cheap LED Christmas lights, but I cannot see it here at all on any brightness level.
Low brightness is also nice for generic background lighting. I tend to use just off, low and high, and ignore brightness levels 2 and 3.
4: The AC adapter is pleasantly tiny - you could mistake it for a cell phone charger - very efficient light source I guess. The light also returns to the same brightness level if you disconnect it from AC (at least for short periods, did not test overnight) This one thin wire is the only wire you'll see - all other electricity travels through the secure mechanical connections.
5: If you have a smaller workspace, like just a phone and notepad, you might want to check out the mini 4 LED version. This full sized one is for a larger work surface.
Very impressed.
My only suggestion, and this is tiny, is that the on and off press buttons could be a bit lower down on the neck. There's a slight wobble when you press the on button - any similar design would have that - and it would be minimized if they moved the buttons down an inch.
And I guess it could have buttons for each power level, but then that would be 5 buttons instead of 2, and that makes it more complicated, so never mind. Or just have 2 brightness levels, low and high, and off, requiring only 3 buttons. When you turn it on, you do need to cycle through the 3 lower brightness levels to get to max. And then to turn it off, you go back down through those 3 other levels. Not a big deal, this is a TINY and possibly bad suggestion.

Not the typical light, But I love it! I use it to light up my keyboard on the low setting. I may be buying a 2nd light for reading. Can be position almost anyway you want and the arm is very lightweight.

While it may seem expensive, you are paying for the technology, design and quality of this fixture. It uses new generation high power white l.e.d. bulbs as opposed to older l.e.d.'s which put out fewer lumens. I also recommend you go with the bright white as opposed to the warm white bulbs which produce a less intense yellow light. This lamp goes together in minutes, is infinately adjustable and comes with a solid as well as bracket base. You have 4 levels of brightness as opposed to an on/off switch. It produces very little heat as compared to halogen or incandescent bulbs. If Porsche made a desk lamp, this would be it.

I needed a lamp to go on a small table that does double duty as a place to eat and a place to work. The lamp had to be as unobtrusive as possible, yet still provide good task lighting and look good against the painting on the wall behind it, as well as the rest of the decor. This lamp covers all of that perfectly. Yes, it's expensive, but I think it's worth it. The quality is excellent and it puts out a good light for getting things done. It will not flood a wide area, but it lights up a reasonably good area for most tasks. It can be adjusted in so many ways that it's like a contortionist. You should have no problem setting it up for almost anything you need lit. It looks very cool and sophisticated, and is so thin and sleek that it almost disappears. You are surprised at how much good light comes out of the narrow head. You can also fold it pretty much out of the way. The base is nice and heavy, but still sleek looking. The little buttons at the bottom of the lower arm are easy to work and simple to use, and the wall wart is tiny. I got the cool white and agree with other reviewers that it avoids the blueish tint and comes across as pretty pure white; definitely not warm, but neutral. I'm very happy with the Z-Bar so far, and would recommend it if you need a stylish, unobtrusive, high-quality light that uses the latest technology and adds class to your space.
Absolutely love this desk lamp! May 5, 2010

I did a whole lot of research on nice desk lamps before I ended up buying this one. What I found was that the desk lamps that you can find in Staples and Office Depot stores (at least around here) are sorely lacking in configurability, style, power consumption, and appeal. There is a large gap in price between the desk lamps I found at Staples/Office Depot/Target/etc. and the nice ones I found online. This Z-Bar LED light, was at the lower end of that price gap and I was happy about that.
In addition, I knew that I didn't want another halogen desk light, having had previous really bad experiences with energy usage, cost, and burns from the high heat. I wanted something stylish and classy-looking, so from what I saw, that meant that the old CFL/Incandescent lamps were out too.
I found some good online desk lamp reviews and it looked like LED lights were very long lasting, very low energy/electricity users, very stylish, and didn't get hot to the touch. Unfortunately, they're also the most expensive right now.
Having looked in stores, and done the research, I settled myself on spending more than $100 on a new desk lamp. I work 100% from home, so I viewed it as a good investment and another step in making my home office a place where I like to be for 8+ hours a day. My two favorite LED lamps were the Koncept Z-Bar High Power LED lamp and the Humanscale Element LED Lamp. I just couldn't bring myself to spend $340+ for the Humanscale Element, but the Koncept Z-Bar's $160 price was a little bit more palatable.
Next came trying to figure out whether I wanted the Daylight or Warm White LED lights, and I read a lot of differing opinions that didn't really help me decide. In the end, it seemed to me like the Daylight LED lights would offer the ability to be brighter, so I went with them. I was worried that the light would be blue-tinted as I'd read in some customer reviews, but if it is (I can't tell?), it certainly doesn't bother me at all. I also read people complaining about flickering LED lights at lower lighting levels, but thankfully I have not seen any of this and think that it's a problem that might have existed in older models.
Koncept does a really nice job on packaging and finish and attention to detail, and my first thought on unpacking and assembling the Z-Bar was that it was very much like something you'd get from Apple.
I am extremely satisfied with my Koncept Z-Bar High Power LED Lamp. The price was not too high, especially considering the current price range for other LED desk lamps, and the quality is truly stunning. I have no problems at all with it, no complaints, and haven't seen any flickering or other sub-par behavior. Would definitely buy again. The only other problem I found was that these lamps are extremely popular right now and hard to find available online. I think Koncept themselves are out of stock on these for at least another month. So if you can find a retailer who still has these in stock, buy one quickly, because chances are, in another hour they'll be sold out too. =:)
