Question: Is this a full spectrum lamp?
Document: Beautiful. Elegant. Perhaps even better is the pure full-spectrum light with six levels of brightness at your finger tips by a circle of six blue lights and an on-off seventh blue light. All elegant, of course.As soon as I unpacked my order, I placed a second, identical order. I chose Red over Black for both lamps.
This lamp is exactly as advertised and the shiny red design is a bright spot. Rarely ever use the full brightness.
Very good light, but too small. It needs to be available with a larger light  so that you can get more desk surface coverage. I still have to use my old flourescent desk lamp to get full coverage. I do like the intensity of the light, it just has a very limited range and a very small base and a short &#34;arm&#34; that doesn't allow you to place it in very many locations.
FOLLOW-UP REVIEW:  Seller was prompt and courteous (Thanks!) to help facilitate a new purchase at a discounted price after I returned the previous lamp for a full refund. This new lamp is in perfect condition, the scratch protection film peels right off, the lamp's red and black colors are very cool, and I love the multiple brightness/dimmer settings.
It is on the white side of the spectrum but not bad at all. This fits the bill perfectly and it gets a 5 stars for function and style both. I could not be more pleased.I tried to show it off to the first person who walked by my desk and they looked at me strange as I enthused about it. That is one person that is not going to get this lamp as a Christmas gift. If it sounds strange to like an object that much then call me strange.
This little lamp is stylish, flexible, and--as an LED--highly energy efficient. Operating the controls is brain-dead simple, and at full brightness it floods a work desk with daylight-type light. It would be a good purchase at a much higher price. At the Amazon price I paid, I consider this an incredible deal. We use it multiple times each day...just touch the little dial with your fingertip and you have as much light as you want.
It even has a cool dimming circular feature that looks high tech. This dimming feature works well as long as my finger is clean ... basically with no hand lotion ... I have discovered. It is a touch sensitive dimming switch so I think this is understandable. I use it on &#34;full&#34; bright most of the time anyway, but the dimmer is a cool looking feature. I am happy to recommend a very good product like this lamp.
Big light, small footprint. I read and write all day and now have two of these. There are a large number of settings, all actually different in intensity, so I go through most of the range in the course of the day as the light changes in my study. I've got two of these now and am thinking of getting a third for my guest room. Nicely flexible neck, friendly light spectrum,
Bought this unit to replace a failing halogen model, and I only wish I'd done so sooner. At full power, this light is extremely bright, yet never generates the kind of heat that my halogen model did. That's a good thing, as my previous halogen model melted desktop items when it would tip forward from time to time.The light is dimmable to one of six settings and, for me, the second lowest power setting is fine.
I looked at dozens of desk lamps at Amazon, then finally selected this one even though the price was higher and I am glad I did. The dimmable LED light has a very good spectrum without glare which is very good for reading. The neck is both very flexible and stiff enough for a wide range of positions. While it was not cheap the value is still very good. The design of the dimming switch looks cool and works well..... overall a very good product.
Answer: yes
