Ok, here is my situation. I originally bought the ultimate light kit with the Eballast. It worked for about a month and then the ballast stopped working. I contacted Brain and he graciously replaced it. That one worked for about a day and stopped working as well. I double checked my wiring thinking that was the problem but couldn't figure it out. I was able to get myself one of the huge traditional ballasts with capacitor and it works fine, but now all of my colors are washed out. Questions:
1. This didn't come with an ignitor. Just Ballast and capacitor. Am I missing something?
2. Will going from E-ballast to traditional damage or alter the bulb? Do I need to order a new bulb?
The brightness is the same, but like I said..the colors are extremly washed out. Any comments would be appreciated

Standard ballasts don't need an ignitor and this would only be used to start the bulbs so as its already working you're good.
There isn't anything major different between the coil and eballast they both provide AC current at the required voltage so the bulb shouldn't care if it was working on the other ballast before. The differences between coils and eballasts seem to be that while coil ballast have no active elements so their waveform has to run at the line frequency i.e. 60Hz from the wall plug (50Hz in europe and other parts of the world), while the eballast can run at what ever frequency they want (I beleive that his is usually 1000 to 10,000 Hz) they can also tune the voltage a bit. The higher frequency give the bulb better control (or so the manufactures claim) although different bulbs react better one way or the other.
As usual nothing is simple the website bellow (Aquarium site) tested multiple bulbs on multiple ballasts and found significant differences in brightness and color temp depending on the ballast but some bulbs worked better on coils while others were better or eballast but had different performance on different eballasts. Color temp varies, brightness varies and lifetime varies. They have another report in which multiple people report on brightness over time, some bulbs seem to break in and get brighter then fade over time (1 year continuous) while others faded quicker even two bulbs of the same model. So the bulb to bulb variations can be significant even from the same lot bulb to bulb. As you can see from the plots some parts of the color sepctrum are the same independant of ballast while others vary depending on the ballast so that means that blue may stay the same while red increase which turns blue into purple etc... So the color is dependant on the ballast, but there is no "one right ballast" they are just different.
