Ok, I am getting different times when to change bulbs
some say 9 months, 18 month +
I am running Sunlight Supply Tek light, not over driven
Sunlight Supply said their Tek light fixture can run up to 3 years with a 30% drop off
I understand over driven bulb would need to be replace at a shorter time span
basically I would like to know how long I have on a set of bulb before my sps start loosing there color
