Question: Fully extended, how far from the base does the lamp adjust to
Document: I use this light in my home office in lieu of spending money on track or other ceiling lights. I have two lights covering two desk surfaces and have a 100 W equivalent LED bulb in each one--one light is a Daylight and the other is a Luxo. The Luxo is more expensive but I actually like the Daylight better because the on/off switch is on the lamp head. I am not able to tell a difference in the quality of the construction. So far so good.
This is at least the eighth or ninth of this type of lamp I've bought over the last fifteen years, so I have some insight into the things.
This lamp works as described, the light it provides is indeed quite white & bright as an artist I can mix my colors any time of day or night. only wish it came in a wider variety of colors.
Excellent product. Provides perfect lighting for hand coloring black/white photographs with oil pastels. Halogen lighting distorted colors & this lamp allows true shading without shadows. Arrived on time & was ready to use immediately without any assembly necessary.
), but when it goes, it's gone, and none of my attempts with a soldering iron have been of avail (everything gets very brittle and fragile). They tend to last a couple years or so at my desk. This latest unit seems to have mostly the same  electrode construction as those previous; we'll see. I will say that the metal shade is larger (see below) and the lamp seems to run cooler than the older ones, so this may decrease the problem.
I found many junky lamps on the market and finally decided to try this one after reading reviews. I am an artist who works in a dark corner of my garage. This lamp illuminates my work area and allows me to see the fine details in my sculptures beautifully, swings easily, and has a super sturdy clamp that doesn't 'give' when I swing the lamp around. I am so pleased with this purchase!
I like this type of lamp. Being able to swing a lamp over the work to get the best light and see what the work looks like under both florescent and incandescent light are qualities I value.Unlike the lamp this one replaced this one is very well built and I expect I will be using it for several years rather than the several months of the last lamp of this type I purchased.
The new fluorescent bulb is larger (28W rather than 22W) and I definitely recommend you buy this version. Part of the reason is the larger shade to accommodate the greater diameter bulb; as mentioned above, it may help the lamp run cooler, and there is noticeably more light (though it's bluer).You can only buy these in white and black at present; previously, they were available in cream, which looks a good deal better in most traditional offices (hint to the manufacturer).
Wow. What a light.Not your normal drafting lamp:  a high quality, professional drafting lamp for artists or architects.It uses two bulbs:  an ordinary incandescent (up to 100W), and a circular flourescent bulb. When they are both on together, the light is supposed to mimic perfectly the color quality of natural daylight.I'm so happy with this light. Would you believe I have 5 of them scattered throughout my house?They used to make a black one, but apparently not anymore.
The springs are covered rather than bare; though one would have been hard put to pinch oneself in the others, they do look a bit neater.I must respectfully disagree that the bulb shipped with the lamp is a "daylight" bulb; the one I received, at least, is an even-bluer-than-usual fluorescent, so much so that I used an ordinary soft white incandescent bulb to try to even out the light color instead of the "Reveal" bulb I would normally have used.
