What is a LED filament bulb?
The filament bulb is a relatively new, designer type of LED bulb. Often this special subcategory of LED bulbs is called the "Edison bulb for the 21st century". In appearance and design, they really do look like classic tungsten bulbs.
These bulbs differ from classic LED bulbs only in their retro look and design. However, the characteristics (and therefore the advantages) are the same.
