Communicating efficient circadian light for SAD therapy

1•galenheninger•21h ago
This is a draft of a social media post I wrote about light therapy. I'd appreciate any feedback on it, maybe especially on how it might be received - how should I revise it to be less potentially annoying or more persuasive? Thanks!

"An anecdotal cure for some people with seasonal affective disorder is exposure to light similar in intensity to daylight (104 - 105 lumens/m2) which normal therapy doesn't provide. E.g. at least ~16 8 watt bulbs at 100 lumens per watt shining on one square meter. (Maybe using a diffuser and aluminum foil.)

Besides being dim, lamps branded for therapy (with an exception from this year), including the most recommended ones (and most LEDs), also miss the circadian light spectrum. Here’s a database (including light spectra) on led bulbs that don't. https://optimizeyourbiology.com/light-bulb-database

https://optimizeyourbiology.com/best-sad-light-therapy-lamps also has reviews measuring the output of SAD lamps, including the new one I mentioned (SOL PhotoVites). This lamp and the solution above are examples that are good for the goal of efficiency in circadian light and convenient for testing bright circadian light."
