Dimmable ballast help

Has 250/450/600 & 660
Apparently the 660 version is a boost, can i still use that setting on ballast while only using a 600w bulb?

Dont want to blow the bulb or cause issues. Thank you

Yeah the boost setting is designed for the 600w bulb but what they don't tell you is you need to fire it up at 600 and then switch it to boost after 15min.
