Generally it is recommended to replace 1/2 fluorescent bulbs every 6 mont==
hs.  This way there is not as great of a change in light intensity as the==
re would be if you replaced them all at once.   The bulbs do lose their o==
utput over time, which is not always obvious to the naked eye.

If you have not got a dedicated light meter you can use your camera and s==
ee
what exposure it suggests (unless it is an automatic-automatic-automatic.==
)

I miss information here. Light levels decrease with the square of the
distance so distance is very important. What distances are yo uusing?
