10mm Round Top Cool White LED - Sign Backlight (Pack of 10)

About this item

• Large 10mm high-visibility LED - 10 Cool White large 10mm through-hole LEDs producing high visible output for sign making, art installations, and high-visibility indicator displays — substantial size delivers strong visible light
• High-output 10mm cool white emitter - Clear-lens 10mm round-top LED rated 12,000-14,000 mcd at 20mA drive current with a forward voltage of 3.0-3.4V. Narrow 20-30 degree viewing angle concentrates output into a tight beam for high-visibility indicators, signage, and long-throw display work.
• 10mm radial through-hole package - Standard 10mm DIP body with two radial leads on 2.54mm-compatible spacing for breadboard, perfboard, and PCB mounting. Clear epoxy lens provides crisp on-axis output; large 10mm dome diameter delivers maximum visible surface area for panel displays, sign backlights, and oversized indicators.
• Polarity and resistor reference - Through-hole LEDs are polarity-sensitive: longer lead is anode (+), shorter lead is cathode (-). For 20mA drive current with a 3.0-3.4V LED, use a series resistor of 100Ω 1/4W on 5V, 300Ω 1/4W on 9V, 470Ω 1/4W on 12V, or 620Ω 1/2W on 15V.
• Cool white display applications - Tight-beam 12,000-14,000 mcd output at 20-30 degrees suits sign backlighting, channel-letter fills, and outdoor display panels where high on-axis brightness is needed. Also serves as a modern beacon, architectural accent, daylight-tone status indicator, and large-format art installation pixel.
