[Upgraded]Saicoo? LED Desk Multi-Functional Lamp with Sight-Protective LED Panel,3 Lighting Modes (Cold/Natural/Warm),5-Level Adjustable Brightness, Multiple Angles and Positions

This review has been updated. The update is at the bottom.--Original review follows--Zero Stars if i could.. Item came packaged new in a box, arrived in a nice short amount of time. Item did NOT work at all. When plugged in the effect of touching the power on button was exactly the same as if it was unplugged. I swapped out the wall wart with a known good one. The light still did not work. I was unable to swap out the cord since the cord is a proprietary power cord. I did not contact seller to have them replace since I was unsure how long it might take and did not want my 30 days to run out with Amazon. I returned it to amazon immediately.FYI, Out of 32 items purchased this year through amazon, this is my 2nd return. I do not like to return goods.Otherwise the product seemed to be constructed mechanically well. Even though it did not work electronically, it did flex well and I fully expected it to work and to keep it up until I plugged it in.I would like the cord to be an easier to replace one, perhaps of a standard type, so that if it didn't work for some reason I could easily find a replacement (for example, a USB 3 cable might work).Update 18 JAN 2016,After the initial review the seller contacted me and asked what they could do to help. As i had already returned the product to Amazon, I ignored them. A couple of weeks ago they contacted me again and asked if they could do anything to increase my opinion of them, they offered sending me a unit to test. I accepted and I have received another LED Desk Light from them.This light is packaged identically to the last one, the packaging is very sufficient for a product of this weight. The light works perfectly. The light isn't as bright as a 60 watt bulb, but if you are concerned about brightness it would help if you understood how bright an led will be depending on the power it consumes. If you want the brightest lamp look for more wattage, some of these lamps list as much as 18 watts (though I believe those include 5 watts for a USB jack on the lamp).If you were to look at a 10 watt LED lamp and a 5 watt one, the 10 watt lamp is definitely brighter (if other parts of the lamp are equal). That is NOT the lamps fault. Just as a 60 watt incandescent bulb is brighter than a 50 watt bulb (of equal type!), that isn't the bulbs fault. The consumer must understand what they are buying.This lamp has multiple modes. Pressing the "M" switch changes the lamp brightness and 'temperature' using 3 modes. Pressing the "+" or "-" switch changes it through 4 levels. The last switch is an on / off switch. The switches are touch sensitive, no real pressure is needed.The power transformer (or brick if you call it that) plugs into the wall and there is the ability to charge 1 USB device by plugging it into the same transformer along with the light or since the light cord ends in a USB plug, you could unplug the light and charge 2 USB devices. Yes the light would be off, it isn't a magic light it must be plugged into a source of electricity to turn on.You receive:nice box and packaging,an instruction booklet,the lamp part,the cord,the transformer (wall wart).The lamp works perfectly fine, I am using it next to my computer on my desk. It is very adjustable with it's two hinges. The lower hinge rotates 90 degrees. The upper hinge rotates 180 degrees. There are 14 L.E.D.s behind a white plastic diffuser. For my son who does school work at his desk, I bought him a higher wattage lamp. That means it is brighter. This lamp is sufficiently bright for a general purpose desk light. It also costs 3/4 of the price I spent on my sons light.Considering that every manufacturer has an occasional lemon and that the manufacturer contacted me several times to work out a solution.And since the replacement light works perfectly for what it is designed and stated to be able to do. I feel that it is only right to change my rating to a 5. I feel that is the right honest rating considering everything.I set a calendar reminder, I will try to update in 6 months.

I've now bought two of these, and I quite like them. The first one I bought as a desk lamp to illuminate my keyboard and my calculator when studying for online classes at night in a darkened room. After using it for a few days I decided to get one for my bedroom nightstand as well.There are three modes on this light, a "Daylight" mode where the color temperature is pretty white, a "Soft" mode where the color temp is very close to an incandescent soft white bulb, and a nightlight mode which is similar in color temp to a 7W incandescent night light bulb. In addition, all three of these modes allow you to adjust the brightness by a fairly large range. One great feature is the light remembers the last mode and brightness setting when you turn it off so if you run in one mode, that's what comes up next time you turn it on and you don't have to cycle through the modes every time like some products I've used. It does not however remember this setting if it completely loses power.The product feels pretty sturdy, and the base is heavy enough to allow you a pretty full range of adjustment of the arm without fear of it tipping over. Sometimes when using it as a keyboard light I'll get it 2" above the top of the keyboard, almost completely flat. Very handy for reducing glare in a dark room.The power cord is a USB cord with a barrel connector. I'm a little surprised they didn't just go with micro USB but it's just fine. You can power the lamp off a computer, I'm actually running one of my 2 lamps on a USB hub. It also comes with a little power brick like comes with an iphone, and that brick has 2 usb jacks so you can plug in the lamp, and charge a USB device at the same time. Kind of nice if you had to use up your charger wall outlet to plug it in.There is one improvement I'd like to see. The arm only articulates on one plane, so you can move up, down back and forth, and tilt the light towards and away from the base, but you cannot twist it side to side. Having a little swivel on the top hinge would be a cool feature. It's not too big of a deal because the LED's are well recessed so you don't get direct glare, but would be a nice feature to have. Other than that I am pretty happy so far with both of the units I bought.
