Illuminating the way towards a bright design, the Sigelei Kaos Spectrum 230W Mod is not just a normal high wattage device. The Spectrum's signature feature is the 6-Color LED belt which wraps the screen along the front face of the device. Users have the ability to choose from six different colors through a seamless user interface to produce a completely eye catching unit day or night. The LED belt wraps around the large 0.96 inch color display, offering a touch more of color than the traditional OLED displays. The Spectrum requires (2) 18650 batteries (batteries sold separately) which can be replaced though the hinged battery door located on the underside of the device. Integrated with Sigelei's precise technology in temperature control and raw high wattage power, the Spectrum impressively provides a wide dynamic in terms of quality, performance, and pleasing aesthetics to light its way to the top of its platform.
