The SHABBOSLITE has been designed by lighting professionals using the highest quality safe and rugged components: from fire protected high grade plastic to the latest UL and CE listed LED component wiring and FCC listed power adapters. The LED chips are of superior quality and will not flicker nor dim out over time. LED lighting is energy efficient - bright light with minimal wattage usage. The E-Z Slide Shutter has been tested in the closed position with the LED lights on for many days straight for heat-sink and temperature safety. The SHABBOSLITE lamps are large enough for versatile function ability yet can be adjusted to a compact size for travel and packing in the pouch that is included with each unit. SHABBOSLITE is so well designed; you'll want to use it all week!
