I spent $300 on high lumen output light bulbs. 28 200W equivalent LED bulbs and 2 LED corn bulbs. Just a TON of light. Depending on severity either run it all day (late January and February tend to be the worst months), but even 10 minutes in the morning helps substantially. Just a lot of light. You can get hung up on high CRI and full spectrum but just do it badly first, then if it works worry about perfecting the setup. I just kept buying more bulbs and as I bought, I felt better and better.

Edit: this was the blog that gave me the idea, it comes up on hacker news a lot. https://www.benkuhn.net/lux/
