Can I ask you another question? When you have a minute… I’ve got a couple of r o h s LED lights. On the back of the control box is a switch that says K2 underneath of it. Okay when you flip that switch the intensity of the light almost doubles. And the dimmer switch doesn’t dim it down it will dim down the rest of the lights in the unit but not the K2 lights. What is this I don’t have any idea what this is and how do I use it? About burnt the tops out of one of my plants with this particular light. I purchased second hand and don’t know anything about them. I looked online and can’t find any information on them. I’ll thank you in advance for any information you can shed on this. Thank you
