LED-Filament, E27, Globe 60, 4 Watt

METOLIGHT LED-Filament-Bulb G60 - 4 Watt

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

This newly developed LED Filamentlampen correspond in appearance to traditional incandescent bulbs , but have 120 lm / W efficiency 10 times and an average of 20,000 hours 20 times the durability. They correspond to the new energy class F. 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 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 not 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 in the base 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 brightness of a 40 watt bulb - save 90 % in energy costs

Light color warm white 2700K +/- 200K
