Question: How many Lumens?  or, equivalent to what wattage incandescent?
Document: The lamp is well constructed, superior in every way to the flimsy incandescent lamp I replaced. It is also superior to other LED, CFL and high intensity lamps in my experience. It is well worth the price.
Make no mistake this is as far from warm incandescent and CFL as you will likely get. The other caveat is it is designed strictly for very focused, close up illumination. For this requirement it is unmatched! For me, a voracious in-bed book reader, it is perfectly suited to not only very close and bright page turning, but for indirect lower light more 'cozy' reading sessions.And in this, is where I have been surprised most of all!
This lamp was just what I needed for my sewing machine. It is very flexible yet constructed well. It lights up the area I need to thread needles and change bobbins very well. I replaced an incandescent lamp where the rotary switch gave out. This switch is a toggle and seems much better. It does not get hot like my old lamp. I just bought a second one for another machine and I would recommend this led lamp highly.
works well and hold position  very well. Nice  for closeup work where too high intensity could be a problem for you. Nice build quality.
this lamp is a very cool (blue-ish) color light and I found it not quite bright enough to light my whole desk area but it's a great price so if you don't need super bright it will be good.
hooks on to my sewing table and gives good direct lighting and easy to focus on working parts of pattern
great for lighting stuff up very bright at close range. only issue no cover over led so if you are working with metal (dust or small chips) it can get inside.
got this for my quilting shop it wasn't bright enough for my needs but I was able to return it no hassles
a great light! I use it on my sewing table and clearly see a marked difference. I thought I had a good amount of light with the sewing machine light and another, full spectrum, floor lamp less than two feet away. I was wrong. This light makes a huge difference in lack of eye strain because of the bright working area. The brightest area is about 12 inches across.
Worked for a week, was using it one night and it exploded into a flurry of sparks. Im now in the process of returning it via amazon. really thought this would be higher end especially considering the price - save your money and buy a better lamp.
