Takeaway: Good supplemental light for small plants/herbs up to 15" tall, works ok but not very strong.

You’ll receive the grow light and power adapter. The power cord is about 6' long and has inline controls for the light. It has a USB connector at the end that fits into the included adapter or any standard 1A output USB charger. You can also plug this into your computer’s USB ports. The shape of the light fixture on the end is doughtnut shaped and flat. It is made of metal on the outside with a plastic diffuser on the underside. The LED bulbs are not replaceable. The 15” metal gooseneck is flexible so you can adjust the light as your plants grow. I found that it works best when the light is about 1-2 inches from the top of the plant. Since it cannot go higher than 15 inches, it is not suitable for taller plants.

The base on the light is a strong spring loaded metal clamp that has foam padding inside the clip. There’s a ton of tension on this spring so it takes a lot of pressure to open it, so it should keep a fir hold on your desk or table. However, be sure to only clip it onto the surfaces that are completely flat on top and bottom as it does not hold well to decorative table edges. The maximum clip width is 2 inches and there are two fabric elastic bands just behind the jaws that help protect your surfaces from scratches against the clip’s metal edges.

The power switches are about 1 ft down the cord from the clamp and have separate switches for the red LEDs (flowering and fruit production) and blue LEDS (vegetative/leafy green growth). Both colors have high and low intensity settings. You can also use both colors at the same time for balance of both types of growth or just use one color for your application. I've been using the light for about a month to sprout and grow cilantro and started a control batch of seeds on my windowsill at the same time. After 4 weeks of growth, it looks like the grow light ones are doing a little bit better: the plants are taller, greener, and straighter than their sunlight counterparts. However, the length of the stems may be due to some legginess as the plants are having a bit of trouble holding up their own weight so this indicates that the amount of light from the grow lamp may not be strong enough. One thing I noticed with the grow light is that there tends to be a dark spot in the middle when the plants get too close to the light, so I have to continuously adjust the light higher to keep it at least an inch from the tops of the plants.

Overall, I think the grow light did a fine job with the seedlings, though at the rate they're growing, they may outgrow the light pretty soon. The intensity and spread of the light isn't very large though so this light is probably better suited for plants that stay small, like African violets and other miniatures.
