    When do you know its time to change the bulb?
    2 weeks ago mine went out, I took it out and put it back in just to check and it worked; yesterday it did it again, I did the same thing and it worked again, I checked the bulb and it seems to have changed colors, the glass is amber brown...
    Does this mean that the bulb is done or am I having problems with my ballast?

    bulbs normally last about a year before they start getting too dim to be viable but they'd still last a while longer

    Is there anyone out there that can give me a better answer, the bulb is constantly going out now; I've only used it for 7 months.
