PC lamp changeout

[slider101]

How often should PC lamps be changed out? I run mine for about 7 hours aday.

I'm pretty sure they start to lose their spectrum after about 6 mo. 7 hrs is a little shorter than most people run their lights for so you might be able to go a bit longer.

They have been in use for 6 months. They just dont seem as bright as they should anymore. There is 265w of total light there so it is probably about time to change them out. THanks.

i replace mine about every 8-10 months.

What do you mean? Change one at a time until all 4 bulbs are changed?
