I ordered this despite a little bit of skepticism due to the price, and ended up pleasantly surprised. The overall quality is noticeably better than the ubiquitous Mighty Brite (or its K&M branded version).
But the real killer feature is the ability to change the color temperature of the LEDs. It's something you may not appreciate fully until you have it; it makes such a difference to music readability, eye fatigue, and ambiance. It's essentially the difference between a room lit by florescent, halogen or candle light, and this gives you options.
The width of the light is perfect for a two or three-page spread of sheet music with no spill or shadowed areas. The clip attaches more securely to stands (especially common K&M folding stands) than the aforementioned M.B. lights.
And it's powered by a long-lasting rechargeable battery (another huge step up), and can be used and recharged at the same time with the included power adapter. USB-C makes the charger future-proof and easily replaceable.
The quality is very good all-around, especially for the price.
