Antique led filament bulb - st64 - 4 w - e27 - intense warm white

This LED light bulb looks like a classic Edison light bulb and has a capacity of 4W with E27 fitting. The lamp gives a nice (intense - 2200K) warm white light. The lamp has the look of an old-fashioned light bulb, but instead of a filament, it has very small LED strips. These LED lamps are therefore a cost-saving (only 4W) and very attractive addition to every room. The filament is formed by a special glass (sapphire) substrate on which a very large number of small LEDs have been applied and which are covered in their entirety with a phosphor layer.
