The clamp is nice and sturdy. The timer works great and stays on schedule until it’s unplugged or manually powered off. They are very sturdy and clip on yo almost anything.

The brightness is legit from the plant’s perspective. The two adjustable bars enable me to utilize it for two shelves. Adjustable lighting and timing seems more accurate than most others.

These are perfect for my 2 hibiscus plants that i have to bring inside when it gets cold. The coleus grows each day. The lamp provides artificial sunlight to indoor garden starts and plants.

The instruction manual is absolutely useless. Product and box was damaged.

The light is not enough to imitate the sun. When you put the light meter near the leaves it's pretty much getting zero. However this product generates loud radio frequency interference (rfi) noise spikes every 40 khz.

The light ring on top is heavier than the post. Fix is to drill small holes in the rim of the pot. Works great for my indoor venus flytraps.
