Blue LED Necklace $45.00

This is an absolutely stunning necklace. The easily replaceable battery* is in the clasp. Shutting the clasp completes the circuit, lighting the light-emitting diode (LED).

The blue LED is embedded within a genuine Swarovski® crystal. A blue glow with soft rays is created as the light exits the crystal.

The color range of the reflections is not well represented in digital photographs as they extend the full visible range. Ambient light is reflected and refracted to complete the effect.

Light-emitting diodes (LEDs) are the scientific opposites of photovoltaic solar panels. In that case, light causes a current to flow. With an LED, the current causes the light to shine.

Dimensions: 17" (43.2 cm) long coated metal wire, 2/5" (1 cm) cubic-based crystal.

*Battery: included 3 Volt lithium. Runs about 60 hours.

Gift wrap orders: input salutation in the comment section at the end of the ordering process.
