I'm looking to transition from t5's to metal halides. I like the look of halides better. The few questions that weigh on my mind are
1. I see two different types of bulbs, mogul base and double ended. Is one better than the other?
2. How do you choose the right watt bulb? My tank is 48" wide and 24" deep. I know I need two because of the width but what is the best wattage (70, 150, 175, 250)?
3. How do you choose the k
rating. I see all the way from 10k to 20k. Is it better to purchase a fixture with only halides (maybe 14k bulbs) or 10k halides with pc
's with dual 420 and 460 actinics?
4. What about brand, any to stay away from. Is current USA any good? What about used?
5. Last, maybe off the topic, but what about a fixture with moonlight led
's? Are they of any value other than looks?
