Ordered this model after reseaching LED lamps on many web sites. This is an excellent lamp for my computer desktop. The silver looks great against my Dell brushed aluminum LCD monitor. Positioning is flexible with the double joints, twisting lamp bar, and included heavy base or clamp mount. Construction has a very solid, durable feel yet is lightweight. Four brightness levels provide more than enough light. I keep it on 3 for computer work. Really like LED low heat and limited angle of projection. This allows me to position this just in front of my monitor without producing screen glare or shining back in my eyes. Yes it is more expensive than most but since it gets used all day every day it is well worth the price to me.

I received this item as a Christmas gift a couple of years back. I loved the look of it, and it fit into a very tight spot between my bed and the wall with the including clamp. Shortly after setting it up, I noticed that the light would flicker in intensity intermittently while using it. The problem was off and on, but very annoying for a device you use to read at night by. I contacted Koncept customer support and they were willing to look at it, if i sent it in to them at my own expense. I did so, and after a couple of weeks received the same unit back, with a statement that they could not verify the problem, but replaced the power brick anyway. This did the trick, and I happily enjoyed it for almost a year. Shortly after the one-year warranty expired, the switch to turn it on and off died altogether. A quick google of the issue shows me that it is not isolated at all, and that they used a switch that does not stand up well to use over time. Despite several attempts to contact customer support over the design issue, they were unresponsive.

So while I love the design of Koncept's lamps, I cannot and will not recommend their products to ANYONE.

I had some apprehension about such an expensive desk lamp, but I am glad I took the plunge. I was looking for a non-fluorescent articulating desk lamp. Most articulating lamps need constant fiddling/tightening, and don't hold their position very well. The Z-Bar stays right where you put it. No fuss, no tightening or loosening. It also has a tiny footprint. I am using the included desk clamp to attach it to the desktop hole made for wires.

The lamp puts out good light. It doesn't irritate me like fluorescents, and it is almost soothing (I purchased the "Daylight" model). The six individual lights do create a slight six shadow effect. If you can, set the light so that it illuminates from the opposite of your dominate hand (if you are right handed, have it shine from the left so as not to create a shadow from your hand onto your work.

The Z-Bar puts out good light wherever you shine it but it does not cast much ambient light, and the work area is somewhat small (read: if you are looking to light up a room, this is not what you want). You can raise the lamp higher for a broader area.

Bonus: this sucker does not get hot (pretty warm, but not hot). At any time you can touch the lamp without fear. It also uses only 9 watts at full brightness (compared to, say, 60 watts for a normal incandescent).

My only other complaints are niggling. Turning the unit on/off requires 4 presses of either the + or buttons (though the buttons are of good quality and easily accessible). Also, it is a contemporary looking light. Not my style, but I will accept its function over form. Despite the look, it is fairly non-obtrusive, and it goes with pretty much any modern-day office gear (I got the silver).

This is a great and functional product of high quality. After a childhood of being hit on the head with a burning hot desk lamp that wouldn't stay put, I feel that I am finally beginning to see the light (or is that the result of repeated head trauma? ... ). I recommend this product! If you spend a lot of time at work and hate fluorescents, you may wish to spend a bit of scratch on decent lighting. It's a quality of life issue.

(side note: I originally bought the mini-high power led desk lamp. It was nice, but too dinky, so I returned it. I would only recommend that model for a very small work area.)

Honest reviews on Z-Bar High Power LED Lamp- Silver/Cool Generation 2

The light is REALLY concentrated, as in only 1 foot of space receives 90% of the light. This light is sufficient for up to the width of an open text book, but not enough to light up more than that text book or your whole desk. Also, I can see dark spots on the lit area that correspond to the gaps between the LEDs of the bar. It's a little nauseating when I'm trying to study, and it's apparent enough that I can't ignore it. The z-bar is really light and mobile, but I don't move it much from my desk. It doesn't emit any noticeable heat, but the bar gets really hot if you touch it (duh). Did I regret buying it for so much money? Yeah, as you can see I'm pretty dissatisfied with the illumination and those dark spots.

I could have bought a much less expensive desk lamp but I am a tekkie and this lamp looks so good on my desk.

I had originally ordered the 'HIGH POWER' with 6 Next-Gen high power LEDs

& Built-in 4-step dimmer, but due to a mix up somewhere I got the 'Super Bright 66-LED Z-Bar LED Desk Lamp By Koncept', instead. I was somewhat disappointed until I tried this one and found it to be completely capable of illuminating my desk top to a comfortable brightness level.

I notified customer service people at Bigamazonstore (the Amazon seller) of the shipping error, and they e-mailed me very quickly with an offer to send a return shipping label and a swap or credit may account with the difference. I opted for the credit. If I knew the 'HIGH POWER' version was significantly brighter than this one I would have waited for the swap.

I find the light quality to be great for reading with my aging eyes. Text and graphics 'POP' right out of the paper. The light is bluer than sunlight and some people might prefer a warmer light. Without breaking out my light meter and running comparisons I would say this light is at least as bright as a 2 tube fluorescent lamp but with no buzz, no flicker, instant on, and one quarter the power consumption. I wouldn't want to use this light to grade high quality photos for a magazine layout.

Again my hat is off to customer support at Bigamazonstore for their quality response.
