*by S***M on September 26, 2025*

All the bulbs worked, and the light is great! Good value for the money. Better prices than the brick and mortar stores! There was no flickering coming from any of the bulbs (needed 1, but tried all 6)! Just started using the bulbs, so I don't know how long a lifespan they have.
