This bulb is the real deal! As my tests showed, this product emits a consistent and flicker-free light that's perfect for any workspace or living area. Its frosted glass also provides a soft and comfortable glow that's easy on the eyes. The certification ensures that it's a safe and reliable choice for any electrical project .The only con is that it's not dimmable, but that's hardly a deal-breaker for the overall quality. i highly recommend this superior bulb!
