Reeflux bulbs

In an old post from reefcentral, Chris had stated that your bulbs were okay to be overdriven on hqi ballasts and that you had tested them. They were talking about 250 watt mogul base bulbs in that conversation, but I have 3 m81 150 watt hqi ballasts and would like to run mogul base 175 watt lamps on them. Are your lamps safe to operate like this, knowing that I'd be sacrificing bulb life? Thank you in advance for your time
