 So this is my Mars Hydro grow light is a TSW 2000 and this has been working great in my Mars Hydro grow tent to grow food. I've grow a variety of vegetables and fruits throughout the winter using this light So the cords that are holding this light are just connected to the frame of the tent and you have the ability to adjust the height just by Pressing the buttons and adjusting them lower or higher as needed So it comes up with the on-off switch and a button here to and adjust the intensity of the lighting And I just run the power cord through one of these ventals in the tent and have it connected to a Power bar and a timer so that my light and fan come on for a set amount of hours each day So I've been growing food in this grow tent all winter long I've had tomatoes peppers lettuce strawberries cucumbers and Pretty soon. I'm going to be using it to start my seedlings for my outdoor garden
