The internal design of the crystal lights uses semiconductor technology that minimizes power consumption with high candela light output while using very high efficiency LEDs. The power source used is standard single phase house current 120 VAC converted to a standard 12 VDC power system for simple and safe low voltage indoor operation. This is accomplished by the included AC wall mount transformer/DC convertor.
The light source LEDs are rated for thousands of hours of operation so this is ideal for sustained use. Virtually no significant heat is emitted so the light cups and glass protective covers remain cool to the touch. Please note that your AC wall mount transformer will have a longer MTBF (mean time before failure) if it is not left plugged into the wall socket when it is not in use for extended periods of time. Remember never to use anything other than the authorized/supplied transformer with this product. Any other use will void the warranty and can permanently damage your Archangel Crystal Light device.
The glass crystal covers are non-coated for maximum light frequency transmission so all the emitted frequencies of the LED through the Vogel cut crystals remain intact. This is also added protection of the Vogel crystals from human contact, oil contamination and damage.
The internal printed circuit board is of a dual layer design with a higher quality substrate for maximum connectivity and conductivity. Some other manufacturers may only use a single layer and lesser quality substrate but ours were selected specifically for serviceability, durability, and longevity.
