In a month and one week , my cattis grew from lifeless to this !!

Amazing light, incredible value. The light is super bright well made. I have it in a Vivosun Pro 5x5, I connect to controller really easy.

Much brighter than I expected. Will definitely be getting these again.

These were purchased to replace a standing light that had 5 bulbs, I bought 4 of these in total. They only have yellow light, which dims or brightens depending on what you choose. the clamps work pretty well, but they do wiggle. overall they work for my plants but I saw better growth when I utilized the multicolor lights and not just the yellow light. The timer works well, I just suck at remembering to turn them on at the right time of day, unplugging, and power outages means I have to redo it. each light has two bulbs, a remote on the cord, the cord itself and a usb box to fit into the receptical. these a big and blocky, think phone charger style box, and hard to fit on extension cords. the cords themselves are too short to get any decent height on them, as they don't reach more than 3 feet from whatever plug you use.

The timer, Durability, functionality depends on your placement and the space your working with. But for the area I have the Coverage has been overall well Covered. I had trouble starting the plants because my lights were too high but now the Plant health is good. Color option is not good when your filming in that area.
