Several brightness/dim levels. Timer works well.
Bought this for new shelf. The lights are usb but comes with the plug outlet.
Brightness function lets you dim or make the lights brighter. I usually have it on for about 14-16 hours a day with 12 being at it's most brightest setting. Also the levels of brightness, tho i think this should go brighter than 60.
The bulb is not strong enough to provide adequate light to the plants. Goose necks are very hard to pivot. Stopped working after 3 months, can't find how to contact seller.
A bit concerning. Do not buy. This item is terrible.
