Many people want to know what the difference is of appearance of 10k vs 14k bulbs. Recently I upgraded from 10k to 14k phoenix MH bulbs. Here are the pics of the tank with both bulbs so you be the judge.
10k Bulbs:
14k Bulbs:
Well there you have it, and if the glass looks dirty that is because I need to clean it.
In my opinion I really like the 14k phoenix bulbs and I like how the color pops. The blue is a very nice color. I will miss the 10k to a degree as nothing looks more like natural sunlight than the 10k bulbs. When I had a friend over they loved the look of the 10k bulbs and did not like the look of our T5 setup (half white half blue) as he said the 10k bulbs looked more natural. We will just have to see how things progress.
