400w electronic ballast?

[LawnTodd]

I have blueline 400 watt electronic ballasts and need some input on bulbs. I usually run xm 10k's but was looking for a change. I will probably stick with 10k. I like the crisp white and will also be running URI super atinic for blue tint. What are some good choices for growth and color?

If you aren't afraid to spend $$$ on bulbs, the Gieseman 14.5k bulb looks great on my electronic ballasts. It's a very crisp white bulb.

I've been running them for about 1.5 months for 4 hrs/day and growth has been very good.
