High Visibility, Double Reflection LEDs
DR-Series
Get Twice the Brightness or Use Half the
Energy of Typical LEDs
• Double reflection structure improves beam directivity for increased brightness comparable to incandescent and similar
forms of lighting.
• Compact, 8.5 mm diameter LEDs with large luminous area.
• Designed for high-current applications.
• Greater purity of hue compared to other light sources.
• Available in red, orange, yellow, blue, green and blue-green.
• LEDs require little or no preventive maintenance, increase
reliability and reduce cost of ownership compared to incandescent lighting.
• Through-hole mounting models; surface-mount versions
available soon.
• 100% quality: each LED is tested before shipping.

■ Optical and Electrical Characteristics (at Ta=25°C)
The color of light emitted by an LED is normally identified as a peak wavelength (lpk) measured in nanometers (nm) and also by spectral half
bandwidth (secondary).
