Sapphire Quality LED Filament
5 Year warranty!
Perhaps you have seen this sticker on one of the boxes for our LED filament bulbs?
We now offer 5 years warranty on all of our LED filament bulbs.*
We set high standards for our manufacturer. For example colour temperature and cooling are very important. Our light bulbs are cooled by a special gas, because of this our lamps achieve a higher effeciency than the average LED filament lamp. Another big advantage of LED filament lamps is the much higher beam angle than previous generation LED bulbs that required an extra heatsink.
Thanks to the high quality of sapphire filaments and the gas inside the bulb, our lamps have a life expectancy of up to 30.000h when used in a typical household. The lamps produce on average 130 lumen per Watt and have outstanding heat dissipation. All of our light bulbs can be dimmed perfectly with the right dimmers!
*Warranty only valid with proof of purchase and the malfuntioning filament lamp. Warranty only valid when used in a typical household setting (8 hours a day).
What is Sapphire Quality?
The LED filament is formed by a support made out of sapphire, a large amount of small leds are placed on that support, these LEDs are then covered in fluorescent glue.
Afterwards the filament is dipped in phosphorus, which gives the complete filament it's typical yellow colour. The fluorescent colour of the phosphorus, supplements the light spectrum in a way that produces a pleasing warm white light, with a high CRI value.
There are two qualities of sapphire filaments, a thin version and a wide version. We only use the wider version, which equals the best quality and highest life expectancy.
