Ok, so over the weekend I was able to get two 16.5" T5 bulbs mounted in the canopy, in addition to the stock PC's!!!
One bulb is an 18watt Actinic and the other was a 10K daylight. There is a single refelctor that goes around both bulbs.
After finishing the job and lighting it up for the 1st time, I could not believe the difference. My corals immediatly looked more colorful/brighter and I could see detail in the live rock from across the room that I could never see before. It was well worth the time and effort. It took me almost 3 hours from start to finish.
Now, with that said, there is a couple things that I will be changing in the near future. I will add one more set of T5's (1 more 18watt 10K and 1 more 18 watt Actinic). These bulbs will go all the way in the front and the PC bulb that is there now will go where the moon lights are in the pictures below. When its all said and done, i will have 72 watts of T5, and 73 watts of PC lighting.
I didnt do a very detailed job of documenting the modifications so far because when I decide to add the next 2 bulbs, things will have to be done quite a bit differently. I will do a better job documenting in the future, for now, please take a look at the pics below and let me know if I can answer any questions.
