Lampat Dimmable LED Desk Lamp, 4 Lighting Modes (Reading/Studying/Relaxation/Bedtime), 5-Level Dimmer, Touch-Sensitive Control Panel, 1-Hour Auto Timer, 5V/1A USB Charging Port, Piano Black

I got this lamp to use on a grand piano at church. The arm reaches across reasonably well from the side (though it doesn’t extend far enough to be fully centered over the music desk). The multiple color temperatures and brightness levels are very helpful for accommodating the preferences of various users, and all our pianists seem to like it.It works smoothly and perfectly... in most keys.BUT if you like to play in D-flat, beware! I just discovered that the resonance point of the casing appears to be a D-flat (138.591 Hz). The plastic started buzzing quietly when playing strong tonic chords in that key. This was, of course, horrifying.I assume the same disturbing outcome holds true when playing in C-sharp major, since the identical notes are used, but I only had sheet music in D-flat today. More testing would be needed to determine whether the issue extends to enharmonic keys, but this didn’t seem urgent to share here, since:• I didn’t want to go into too much detail that isn’t relevant to the average consumer (because we all hate that), and• Only psychos play in C-sharp major anyway.I realize this acoustic phenomenon may not affect all potential buyers of this lamp, but it seems like this particular harmonic bug could be mentioned somewhere in the description—if not in the product title itself—just so that members of the five-flats-loving community have some warning.Oh, also, the buzzing stopped as soon as I moved the arm slightly, so there’s that.

Very sleek, modern looking lamp with a variety of lighting levels. It matches my black glass desktop very nicely, adding a sophisticated modern look. Contrary to what some reviewers said, I think it has a relatively small footprint on the desk, which is nice because I'd rather utilize the desktop space for working instead of a huge lamp. I've wiped it down here for the photos, but do realize that it is a dust/fingerprint/cat hair collector. Smudges show up, so if you're not willing to wipe it down every now and then you might be disappointed with it's overall aesthetic look. Pro tip: I keep a pack of Pledge multi-surface wipes (Pledge Multi Surface Everyday Wipes Fresh Citrus, 25-Count (Pack of 4)) in a drawer near my desk to wipe both it and the lamp down - takes a few seconds and looks as good as new.I mostly use this lamp at its lowest setting, as it provides a nice ambience to my work area. Each of the preset light levels can be brightened and dimmed. If I'm going to be doing real work, the light gets bright enough by itself to make reading from a textbook or paperwork comfortable and without strain. Usually one of the reading or middle settings is as bright as I'll go for reading actual pages from a book, and I only use the brightest settings if I'm struggling to see something small like jewelry or I'm fiddling with some component or part of my computer. It does get quite bright. I haven't used the timer function, but there is an automatic 60 minute timer included. Overall, it's a versatile little lamp.I got mine on sale at Christmas during a flash sale, for thirty something dollars, and I think it's well worth it. The listed price, however, is complete rubbish - total waste to pay full price regardless of how well it works, as it is simply made up of plastic and LED bulbs. Wait for a sale and you'll be happy with it. I've included photos of the lamp with various light levels and in different positions.

I received this as a Christmas present after borrowing one from my brother for an extended period, so I knew exactly what I was getting when I opened the box.Pros: There are enough brightness and temperature settings to make this desk lamp practical for almost any scenario, thanks to the many LED bulbs inside the arm. I have not used the timer feature but I imagine it would be helpful in certain situations. The lamp sits on a non-intrusive but relatively solid base, and this combined with the hinged (and swiveling) arm means that it can occupy a very small footprint, perfect for desks with limited amounts of space. The USB port on the side is convenient as well for limiting the number of wall plugs you use at once. Overall, the mechanics of the lamp function perfectly and make the design work in both form and function.Cons: The arm is made of plastic that looks sleek but is not as solid as it looks. The lamp also attracts large amounts of dust, and (at least for the black model) is relatively high-maintenance to keep clean. The buttons that control the settings are not tactile (which is good), but it takes a while to learn how to press one button without activating others. As these drawbacks no longer affect my daily experience, I consider them very minor.Conclusion: This is the best desk lamp I've ever owned in terms of practicality and functionality. While the design may leave something to be desired for those who want a more traditional-looking lamp, this is a great option for most people. I could see myself replacing this with a higher-end lamp if I ever bought a larger desk, but short of that I plan to use it well into the future.
