So far so good. I'm glad I did some research and read reviews over multiple sites and manufacturers to find these. I can't speak to the exact wavelengths but I felt instant relief replacing the one blue tinged LED bulb I tried for this one. That blue hurt even behind a thick artisan golden glass shade. These seem slightly better than plain incandescents for warmth, but with added energy efficiency and heat safety. Important around children, pets, and pain clumsy people like me. ; )
These came in five five piece packs. Well packed and sealed in moisture retarding packaging over each 5 pack box. All but one 5 pack arrived in pristine condition. I opened that one to inspect and try but it was in great order . If you are in need of this size, style, and brightness level bulb for managing night necessities, doing so without disturbing your circadian rhythms, accent lighting or for migraines I think you would be well pleased with this investment towards your health, safety and happiness. I certainly am.
Thank you to the makers, sellers, shippers, reviewers and everyone in between. I hope you find ease like you've all facilitated for me.
