are possible from a 12 volt DC power source.

Flames are very complex light sources and can be difficult to simulate with LEDs because they are composed predominantly of a spectrum that includes blue, The MEL-CF's average color temperature is 1,550K when all the light is integrated. The MEL-CF uses a proprietary broad emission luminescent resin that is coated on the inside of the emission dome in a nonuniform fashion which creates anomalies and variations in the light output color temperature for a more natural appearance and ambience. The MEL-CF has a wide spectral color content that provides rich toned specular reflections from scenery and objects.

The MEL-CF's light output is equivalent to that of a 1/8" diameter oil lamp or candle wick with a 1/2" flame when operated at nine volts, or a 3/4" flame when operated at 12 volts. The MEL-CF is optimized for high light output at nine volts DC with a nominal power of 0.18 watts operating at 20 mA ref. The MEL-CF is dimmable by either PWM type dimmers or with variable voltage input from 7-12 volts DC. The MEL-CF is well suited for various LED lighting applications such as: • Stage scenery, props, models • Simulated fires, trash barrel fires, • Simulated burning of volatile petrochemicals Pricing for the MEL-CF is: One piece — $5.99 each 10 pieces — $5.75 each

OLED DISPLAYS

Newhaven Display International, Inc., announces full color OLED displays are now available in sizes 1.27", 1.5", and 1.69". Featuring 262K colors, these passive matrix displays have a sharper and crisper viewing quality when compared to LCDs because of their rich black levels and 2,000:1 contrast ratio. These displays also have faster and smoother graphic animations because of their 10 µsec response time.
