Hello:

I think we all agree, driving the Radium bulb with a Son Agro ballast(PFO HQI) is probably overdriving the lamp and reducing the life expectancy.

I am curious as to how long users of this setup are getting out of their bulbs. Can you push the bulb to the 10-12 month mark or are they history after 6-7 months.

Could one push the bulb to a 10-12 months if they increased the ON duration of the bulb. Start with say 8 hours and increase 20-30 minutes every month.

Stephane:

I know you are at the 5 month mark, how much longer do you predict you can get out of the bulbs.
