What light bulbs next?

I am currently using 400w 10k reeflux bulbs run by a 400w electronic coralvue ballast. I am happy but the bulbs seem to stop working every 9 months if I'm lucky. Not to mention the old bulb look with in 6 months. I was considering changing to 10k XM is this a good choice? The tank is a 200g sps set up. All thoughts and experiences welcome

That should be a real good choice. The XM is a PAR monster. I would definitely acclimate your corals with this switch using window screening
