LED-Filament, E27, Globe 60, 4 Watt, dimmable, Class A++ - Kopie

METOLIGHT LED-Filament-Bulb G60 - 4 Watt, dimmable

the great-grandson of the bulb - 10 times as efficient

This newly developed LED Filamentlampen correspond in appearance to traditional incandescent bulbs , but have 110 lm / W efficiency 10 times and an average of 20,000 hours 20 times the durability. They correspond to the new energy class A +. They radiate the light just as both good old light bulb around 360 ° from and are therefore ideal for use in shaded lamps , polders lamps, floor lamps , etc.
With the glass bulb and the heatsink is not longer needed these LED lamps are extra light weighted - only 30 grams! The 8 LED filaments with brand chips EPISTAR based on sapphire (no cheap glass or other substrate ) and radiate the light from all around, just as one would expect from the bulb ago. The LED light is dimmable and not suitable due to the all-round light beam for accent lighting. The LED filaments radiate (unlike cheap products) the light from both sides , since they are based on transparent sapphire glass and coated on both sides.
An integrated dimmable power supply on IC base ( not a simple RC circuit ) powers the LED filaments with constant current and ensures a long service life - even during power fluctuations. The lamp base is welded to the flask and has soldered connections , as is known from the bulb ago Cheap filament bulobs have only plug contacts that provide no more secure electrical contact The glass body containing a noble gas mixture for qquick and easy heat transfer from the filaments to the vitreous (cheap lamps contain ordinary air with high heat resistance)

The 4 Watt lamp comes with 450 lm same brightness of a 40 watt bulb - save 90 % in energy costs
