Well I was one of those "lucky" feds who got a 35 day paid vacation and had plenty of free time to get around to upgrading my LED grow light. I added the 4 additional COBs and drivers then tidied everything up. I got the wires covered in heat shrink and the fan permanently mounted on a shroud. Also, I want to somehow cool the drivers with a little forced air because they got quite hot last year and I had a failed driver. I will probably get some cheap plastic tube from the hardware store and mount it directly above the fan and duct the airflow around the drivers.
Now the total output is approx 100W. While this might seem high I believe it will give me some flexibility on positioning the grow light that I previously didn't have.
LED Grow Light Version 2.0 coming soon!
