The only thing I would be wary of, more than the wattage, is the low PAR of Hamilton 14000k compared to some other bulbs. Iwasakis are expensive but apparently have very high PAR, comparable to 250w according to Sanjay's tests (lighting guru).

Maximum PAR for 175W bulbs depends on the ballasts he's using, according to Dr. Joshi. If they're magnetic (likely) then the AB 13K bulbs eke out a bit more than the Iwasakis. But if he's got electronics then the Iwasakis win by a mile (comparatively).
