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.

These lights emit great light for seedling growth. They emit lots more light than the ones i had before. I have several grow lamps, and these units seem to provide the right spectrum to spurt growth.

The lights are good! They work great and are long lasting. Packed well. I solder it back and it works like new.

Price and performance make these excellent for our 2'x4' space. The possibilities are limitless. My only recommendation is to have these available in a 4ft length and half the width, as well as the square format.

The hanging device is great. They come with cable hangers and cords. Would have been better if the hanger was split into 2 sets of 2 wires.

Neither light powers on when plugged in. No switches or fuses to check. Not the stated 45 watts.

The lights have to be basically on top of the soil / seeds to be beneficial.
