Man, that's a sweet looking fixture! Awesome DIY skills. I've been contemplating ditching my 6 bulb tek fixture and getting a reefbreeders photon 24 with 2 24" t5s retrofitted on it, 1 bulb each on the front and back. With your experience with the reefbreeders fixture, is this worth doing? Or I could try my hand at retrofitting the tek with 2 bars of LEDs after removing 2 t5s. Dang, your fixture just threw a monkey wrench into my plans.
