VHO Bulbs...How Often Do/Should You Change Them?

[StinkinTuna]

So how often do you change your VHO bulbs?

Better yet do you know how often you should?

When I had them, I changed them once a year.

I change mine at six months. You can tell a huge difference at just six months...

I just changed mine after a year and WOW!!!
What a difference!

Didn't even notice how much light intensity I lost untill I changed my bulbs!

Yes gflat, I think every 6 months is about right.....grrr more expenses of the trade
