I have a hamilton system that runs 3 175 watt MH and 2 4o watt flourescent bulbs. It's about 5-6 years old. The MH work great, but the flourescent bulbs are real dim and sometimes flicker. Any idea what's going on and how to fix it? Any recommendations on someone who could work on it locally? Bulbs are 1 month old, so that's not the problem. Thanks for any help!!
