Product overview
Overview
PRODUCT
The XLamp® XP-G2 LeD builds on the unprecedented performance of the original XP-G by increasing lumen output up to 20% while providing a single die LeD point source for precise optical control.
The XP-G2 LeD shares the same footprint as the original XP-G, providing a seamless upgrade path and shortening the design cycle. XLamp XP-G2 LeDs are the ideal choice for lighting applications where high light output and maximum effcacy are required, such as LeD light bulbs, outdoor lighting, portable lighting, indoor lighting and solar-powered lighting.
FEATURES
• Available in white, outdoor white and 80-, 85- and 90-CRI white
• ANSI-compatible chromaticity bins
• Binned at 85 °C
• Maximum drive current: 1500 mA
• Low thermal resistance: 4 °C/W
• Wide viewing angle: 115°
• Unlimited floor life at ≤ 30 ºC/85% RH
• Reflow solderable - JEDEC J-STD-020C
• electrically neutral thermal path
• RoHS and REACh compliant
• UL® recognized component (E349212)
