how long of high output can i expect from these and wat are the signs my bulb/s r defunct?

Color shift, degrading of coral color, algae growth are the most comon things that happen when the bulbs are on the end of use life. Excessive bulb burn at arc points inside the bulb are a great sign that it is bad or going bad. MH bulbs should be changed every 6-8 months even though most people go for up to a year.

It depends on the maker of the bulb, usage (time on per day), type of bulb and preference.
