I haven’t looked into this yet. If true not that difficult or very expensive to use other light sources.

So, is it too much LED exposure or too little sunshine that is the problem?

I interviewed Scott Zimmerman recently. He makes the Nira bulbs. He says to go outside to get full spectrum light but if you are stuck indoors, get as close to real full spectrum as possible. His bulbs use low power incandescent filaments for red and NIR wavelengths plus a LED for visible light.
The problem is a lack of red / NIR. LEDs don’t make it and windows block it.
Red / NIR cause mitochondria to make more ATP while blue wavelengths decrease ATP production. The blue is not bad unless it comes without red /NIR, which never happens in nature.
Episode coming out shortly.

I have changed my mind for now since incandescent light bulbs seems to emit UV.
I would need to be sure that a light source doesn’t emit UV or other harmful light to be sure to use it.

These are $27 per bulb?

Yes. With a 50,000 hour life that’s about 25-50 years and about $0.50-$1.00 per year. Might be worth it. I bought the lamp and a bulb to get the DC power (no flicker).
