Hi dr.h00k, thanks for the compliment! Sounds like you have quite a library of lighting! I can certainly understand your desire to cut back and lower energy costs. Well, most of our lights are designed for commercial growers. Based on your current set up, our Lumenator 2x units would be the best choice. They are 180watt lights that cover up to a 3x3 area. Most growers pull eight ounces from under each one. You can start with a couple and see if you want to switch your whole room over. We also have a larger light, the Dominator 2x. That would cover a 4x4 area at 435watts; comparable to nearly 1000watts of HPS. And our largest unit is the Dominator 2xxl. That one will cover a 5x5 area at 650watts and will blow 1000watts of HPS out of the water will yield, taste, aroma, and density. These are all great choices. And it's great timing to buy because we just lowered our prices and we still offer the discount code for 420Magazine (an additional 10% off). Thank you for reaching out and congrats on being able to retire soon! Lucky, lucky!!!
