How do you pronounce Stratos?

Excuse me, could you please clarify the pronunciation of the word "Stratos"? I'm a bit unsure how to say it correctly. I've heard it pronounced in different ways and I'd like to ensure I'm using the most accurate pronunciation. Is it pronounced with a long "a" sound like "stray-tos" or perhaps with a shorter "ah" sound, more like "strat-os"? Or perhaps there's another way I'm not aware of? I'd appreciate your guidance on this.
