400w Aquaconnect 14k SE bulbs, how long will they last?

[raynist]

If I use regular electronic ballasts will I get more than a year out of them? They are very expensive but I don't think you can touch the par with another bulb.

Since they are HQI rated, how long should they last if I used an HQI ballast?

Isnt a AC HQI rated? Meaning a electronic ballast would actually not run it too its full potential.

Think it would easilly last a yr on HQI/M80 ballast if it is actually HQI rated which i think it is

i run the 250w on electronics for 18 months.
