> A minimum of 10 100-watt bulbs in my experience, and even more is better.

Plugging in some rough numbers, that seems equivalent to a ~170W LED flood light. A 200W version is $70 from Amazon (e.g. [1]). Are the emitted wavelengths crucial or is such a lamp on a timer a viable way to get early "sunlight" in the winter?

I think CRI does matter, I’m guessing the parent post saw something like this article.

That may have been exactly the article I saw, there's certainly more useful information in there than I can answer. I pretty much just took away MORE BULBS.

The setup that I have... I have 5 led flood lights, 1 3000K, 2 4000K and 2 6000K.

I point them at the ceiling to get diffused light. I use different combination of some on / off to get the right warmness depending the time of day. Ie. 3000K in early morning / late in the day. Combination of 3000K and 4000K for around 9am. 2 4000K if I feel sleepy.

They work quite well. I suggest trying it out if you have seasonal affective disorder or trouble sleeping
