Question: Can it work overseas (220 v)?
Document: I need the maximum brightness to do my work--and I get it.
This lamp exceeds my expectations. I really like it and it works great for the close jewelry making work I do.
I was in a desperate need of a bright lamp, primarily for reading and office work. This lamp is high quality and far exceeds my expectations
Gives good light for a desk or close work. It works well and gives various levels of light. I would recommend it.
Very hard to turn off and on. Sometimes the switch is not sensitive at all, rendering this lamp all but useless!Seller sent a new lamp promptly. Seems to work fine!
Love this light! Bought it for work. Perfect size that fits under my shelf overhang. Love the flexibility of the lamp plus all the great light settings!
I needed a light for my work desk that I could adjust the density of the light without it getting hot. This light works perfectly.
The best light for studying with concern for quality of light AND a small work area (large books n stuff spread out) simply the best for that task.
This is the best LED desk lamp I've used so far. On/Off switch and variable intensity work & feel great. Light color is pretty good. Feels substantial.
The lamp remembers the last setting you had it on (after turning it on/off) which is convenient. As mentioned earlier, the lamp is excellent for illuminating a work area to read or write, but it's not tall enough to be put above a computer monitor.
Answer: no
