The graph shown below assumes that the system design employs good thermal management (thermal interfacematerial and heat sink) and may vary when poor thermal management is employed. Please refer to the Mechanical Dimensions sectionon page 11 for the location of the Tc measurement point.Another important factor in good thermal management is the temperature of the Light Emitting Surface (LES). Cree recommends amaximum LES temperature of 135 C to ensure optimal LED lifetime.

See the Measurements section (page 21). Cree XLamp CXB3070 LED order codes specify only a minimum flux bin and not a maximum. Cree may ship reels in flux bins higher than the minimumspecified by the order code without advance notice. Shipments will always adhere to the chromaticity bin restrictions specified by the order code.*For 80 CRI minimum LEDs, CRI R9 minimum is 0 with a 2 tolerance. For 90 CRI minimum LEDs, CRI R9 typical is 60.** Flux values @ 25 C are calculated and for reference only.Copyright 2015-2019 Cree, Inc. All rights reserved.

XLAMP CXB3070 LEDRELATIVE LUMINOUS FLUXThe relative luminous flux values provided below are the ratio of: Measurements of CXB3070 at steady-state operation at the given conditions, divided by Flux measured during binning, which is a pulsed measurement at 1900 mA at TJ 85 C.For example, at steady-state operation of Tc 25 C, IF 1300 mA, the relative luminous flux ratio is 80% in the chart below. A CXB3070LED that measures 8500 lm during binning will deliver 6800 lm (8500 * 0.8) at steady-state operation of Tc 25 C, IF 1300 mA.160%Relative Luminous Flux140%120%Tc 25 C100%Tc 55 C80%Tc 85 CTc 105 C60%40%20%0%3008001300180023002800Current (mA)Copyright 2015-2019 Cree, Inc.
