ysnsgmn Grow Lights Plant Light 80LED Growing Lamp 9 Dimmable Level 3 Light Modes, Full Spectrum KIGLON Grow lamp with Auto On/Off 3/9/12H Timer, 4 Adjustable Gooseneck Growing Light for Indoor Plant

That clamp is as wide as it really wants to open and does not have the strength to hold the unit. I have it clipped and placed in a way im not really comfortable with but have no real choice. Tried to show in the pictures how the light isnt really focused and how you get light reflected in your face. I dont really trust to try using the timer and its all lamps or nothing, you dont get to choose to just use 1 or 2 per the instructions. The brightness just cycles all the way up and then back down, when it registers the button has been pressed. That last light is one off from the brightest setting avaliable so you see how much light is bouncing around. You get what you pay for i guess. It turns on and off and hasnt caused a fire! Wouldnt repurchase or suggest since the item doesnt match description and has many design flaws.
