it all depends on how long you have used it they run usally around 12000 hours but should be replaced brfore that time is up. you want to make sure you have the same type as in vertical ,hortizontal or a universal which can be operated in both ways. myself i prefer the hortlilux brand but you could also go with a conversion type that would give you some of the red spectrum instead of all blue

Once the germ of personal ambition arises from dormancy, like a dark and evil genius, it will overshadow an erstwhile sweet and sunny mind; left unsubdued, its force increases to proportions such as to sweep away all honor, loyalty, mercy, and love: if there be aught to gain, fair and kindly friendship is sacrificed; gratitude shrivels and dies; loyalty gives place to cowardice; honor succumbs to treachery; and love is laid low.
