I can't tell from your pics wether your grow is in the drawer or behind the desk. Eiter way you have to cool it down. That means getting the hot air out and fresh air in. If you insist on using the bulb that you are you have to move it away from the plants so you don't burn them. put your hand right above them, if it is warm the you have to move it up more, because as I just learnt the twisted leaves are trying to cool off.
