Classic LED bulbs

Until now, LED bulbs had a very specific design that did not look like conventional bulbs. This is mainly due to the technology of the LED which allowed to illuminate only one side; the LED is placed horizontally on a printed circuit integrated into the bulb. The circuit is then covered by a plastic diffuser or opaque or frosted glass. This configuration gives white bulbs very sober, bright and easy to produce.

LED filament bulbs?

The LED filament bulbs look more to their counterpart’s incandescent traditional tungsten filament bulbs, which, thanks to a unique new The LED technology allows you to have very small LED chips, light emitting, in a set of linear filaments or curved. These chips are electrically powered and protected from the outside via a globe or glass diffuser similar to that of a traditional incandescent bulb. Result: a bulb that gives modern lighting with a visual appearance of the filament virtually identical to that of incandescence.

Are there different forms of filament bulbs?


LED filaments can be integrated into bulbs of all shapes, sizes and caps. For example, we have big globes 125mm diameter G125 to create bright decorations, flames E14 for chandeliers or candlesticks or traditional A60 bulbs for the whole house. Filament light bulbs are also available in 2200K warm white or amber colored light with tinted glass to give a vintage look just like our line of Edison or Marconi bulbs. These bulbs are perfect for restaurants, upscale retail stores, or even homes or apartments in which you want a vintage and design look.
LED filament bulbs generally have a shorter lifespan than ordinary LED bulbs, i.e. between 15,000 and 20,000 hours depending on the model. These figures must be related to the life expectancy of a traditional incandescent light bulb that lasts only 1000 hours to 2000 hours for a halogen bulb.

LED filament bulbs retain all the advantages of LED technology:

  • ·         Immediate ignition
  • ·         Long life expectancy
  • ·         Very little heat dissipation
  • ·         Without UV, without mercury
