The Mighty Bright Orchestra attaches with a single clip which also contains the batteries. We found that when centered, the battery pack interferes with the Manhasset music stand and needs to be shifted left or right to prevent rocking. Once there, the clip holds the light securely. Plastic lenses focus the light and the neck can be easily be adjusted to cover two pages of music. More light falls at the top than the bottom of the page, although not nearly as noticeably as with incandescent bulbs. A zipped handle-less bag is included that generously holds the light, power supply, and instructions.
