Photo: An incandescent lamp makes light by passing electricity through a very thin wire filament. The filament gets red or white hot and gives off light as well as lots of heat. That makes them unstable and, to become stable again, they give off the energy they gained as particles of light called photons.
LED Filament bulbs typically have a shorter life span that regular LED bulbs with most rated between 15, and 40, hours but these figures are amazing in comparison to traditional incandescent technology which lasts just to hours. A filament light bulb is just another name commonly used for the vintage Edison light bulbs. Those reproduction bulbs are made to look like the original Edison bulb created over years ago. The word Filament itself refers to the wire or thread inside the bulb which lights up when you turn it on.
Is there a vacuum in a light bulb? If the bulb had air inside of it the filament would quickly heat up and essentially burn up. However, a light bulb contains a vacuum or a specialized gas that doesn't allow the filament to burn. Incandescent bulbs are simple but fairly inefficient.
Does a light bulb obey Ohm's law? The tungsten filament in the bulb does not follow Ohm's law. As the voltage in the wire filament increases it heats up. This is one of the most common questions we have been getting lately. With the LED bulbs widely available everywhere, it seems as people forgot all about the incandescent light bulb.

A small setback for an amazing bulb, but a setback nonetheless. With the design of traditional incandescent bulbs in mind, filament LEDs have a pretty neat retro look about them.
Instead of a container made only partially of glass like other LEDs, the enclosures of filament LEDs are made entirely of glass, just like old-fashioned incandescents. Inside, very small LEDs are placed along a glass or sapphire cylinder, the appearance of which mimics a filament. As a result, many bulbs will have over four different strands of LEDs inside, giving the look of an antique Edison-style bulb. This arrangement also means smaller heat sinks mechanisms to take heat away from the diodes are needed.
The result of these differences is that where traditional LEDs only have a degree light angle as discussed above, filament LEDs have the same range as incandescent bulbs, meaning they can light up all the corners of a room better than a normal LED. So what does it all mean?
Which is the better option? So while traditional LEDs offer more in terms of versatility and bulb life, the elegance of the filament LED might be reason enough to choose it for your lighting needs. LED filament bulbs: what are they, what types are available and how do they compare? The main things you need to think about when choosing an LED filament bulb are: the shape you want—this affects how the light fits in or adds to your current decor more than anything the colour temperature you want—lower means more warm and amber how much you want to spend Jump to: Getting the vintage effect—understanding colour temperature E27 LED filament bulbs range specifications Dimmable LED filament bulbs range specifications What is an LED filament bulb?
