Description
The LZ4-00GW08 Gallery White features warm white light with an exceptional color rendering index (CRI) of 98, as
well as impressive individual R values (R1-16) in industry’s smallest footprint. It enables accurate color
representation and enhances the contrast of retail merchandise, artwork and skin tones, which cannot be obtained
with standard warm white LED emitters. The emitter, based on LED Engin’s LuxiGen technology platform, may be
driven up to 10W of power in a compact 7.0mmx7.0mm footprint. It has the industry lowest thermal resistance per
package size, which allows users to drive the emitter with higher current, while keeping the junction temperature
low to ensure long operating life.

Notes for Table 4:
1.
Maximum DC forward current (per die) is determined by the overall thermal resistance and ambient temperature.
Follow the curves in Figure 10 for current derating.
2:
Pulse forward current conditions: Pulse Width ≤ 10msec and Duty cycle ≤ 10%.
3.
LEDs are not designed to be reverse biased.
4.
Solder conditions per JEDEC 020D. See Reflow Soldering Profile Figure 5.
5.
Autoclave Conditions per JEDEC JESD22-A102-C.
6.
LED Engin recommends taking reasonable precautions towards possible ESD damages and handling the LZ4-00GW08 in an electrostatic protected area (EPA).
An EPA may be adequately protected by ESD controls as outlined in ANSI/ESD S6.1.
