Tungsten filament incandescent lamps are still the prevailing light source for their warm color temperature, high Color Rendering Index (CRI) and that unmistakable glare. Unfortunately, all of these came at the cost of extremely high energy consumption. KEYART set out to achieve all of benefits of an incandescent lamp using cutting edge LED technology and has done just that. KEYART’s Filament LED features a extra warm colour temperature (2200K) and CRI of 90Ra. And by using Chip-on-Glass technology, KEYART’s LED produce light as good as incandescent lamps at a tenth of its running cost.
