What kind of light is this?

Hey dudes and dudets I have this light I inherited from a friend. He said it was a 150 watt hps light. That's what it really reminds me of.... However when I put my plants under it it seems to make the smell reduce and somewhat go away all together.... When I decided to place outdoors for a couple of days of natures greatest the smell is almost overbearing......... So could this light be causein my problems.... I'm wanting to bring her back in because it's an autoflower strain and I understand the thrive with an 18/6 light cycle...... So please help!!!! And thanks

Old hps bulbs lack the UVB required to push terpene production. A 150w hps could cover 3 sqft. If its too high it will be weak.
