Review on 6 Pack ST58 Antique LED Edison Bulbs 60W Equivalent, 2700K Warm White, 95+ CRI Non-Dimmable E26 Medium Base Vintage LED Filament Light Bulbs by Ynot Karlen

With a background in the interaction of lighting and human physiology I was excited to find a low CCT, high CRI, energy efficient bulb. Very pleased with the light. Only downside is that 2 of 8 bulbs have failed in <14 months in hallway fixtures we do not use that often (at most a few hundred hours, not 20K -- note LEDs rated at 20K hours don't fail at 20K they just put out less brightness - often 70% of original or so -- these bulbs do not produce any light). Was reimbursed for the first failure but second just happened. Hope they can improve quality control because if they last 20K+ hours would be a heck of a product.
