Bridgelux SMD 2835 0.05W 3V Product Data Sheet DS1471 Rev. B (06/2025) Product Selection Guide The following product configurations are available: Table 1: Selection Guide, Pulsed Measurement Data at 20mA (Tj=Tsp=25°C) Notes for Tables 1 & 2: 1. The last 6 characters (including hyphens ‘-’) refer to efficacy bins, forward voltage bins, and color bin options, respectively. “00-0-0” denotes the full distribution of efficacy, forward voltage, and color bin. Example: BXEN-40E-21U-3F-00-0-0 refers to the full distribution of efficacy, forward voltage, and color within a 4000K 6-step ANSI standard chromaticity region with a minimum of 80 CRI, 2x1 die configuration, Ultra low power, 2.64V typical forward voltage. 2. Product CCT is cold targeted at Tsp = 25°C. Nominal CCT as defined by ANSI C78.377-2011. 3. Listed CRIs are minimum values. 4. Products tested under pulsed condition (10ms pulse width) at nominal drive current . 5. Bridgelux maintains a ±7.5% tolerance on luminous flux measurements, ±0.1V tolerance on forward voltage measurements, and ±2 tolerance on CRI measurements for the SMD 2835. 6. Refer to Table 5 and Table 6 for Bridgelux SMD 2835 Luminous efficacy Binning and Forward Voltage Binning information. 7. Typical pulsed test performance values are provided as reference only and are not a guarantee of performance. 8. Typical performance is estimated based on operation under pulsed current with LED emitter mounted onto a heat sink with thermal interface material and the solder point temperature maintained at 85°C. Based on Bridgelux test setup, values may vary depending on the thermal design of the luminaire and the exposed environment to which the product is subjected. 9. In order to ensure the accuracy of the test by Everfine sphere ： the test model suggest to use conventional tes t：preheat for 30ms ： integrating time for 20ms. If using pulse model, pulse width suggest to use IP 80-90%. Hot cold test must use conventional test and wavelength accuracy is required to be 1nm. The test conditions must be fixed.

MINOR PRODUCT CHANGE POLICY The rigorous qualification testing on products offered by Bridgelux provides performance assurance. Slight cosmetic changes that do not affect form, fit, or function may occur as Bridgelux continues product optimization. CAUTION: CHEMICAL EXPOSURE HAZARD Exposure to some chemicals commonly used in luminaire manufacturing and assembly can cause damage to the LED emitter. Please consult Bridgelux CAUTION: EYE SAFETY Eye safety classification for the use of Bridgelux SMD LED emitter is in accordance with IEC specification EN62471: Photobiological Safety of Lamps and Lamp Systems. This product can be classified as Risk Group 1 or lower when operated at or below the maximum drive current. Please use appropriate precautions. It is important that employees working with LEDs are trained to use them safely. CAUTION: RISK OF BURN Do not touch the SMD LED emitter during operation. Allow the emitter to cool for a sufficient period of time before handling. The SMD LED emitter may reach elevated temperatures such that could burn skin when touched. CAUTION CONTACT WITH LIGHT EMITTING SURFACE (LES) Avoid any contact with the LES. Do not touch the LES of the emitter or apply stress to the LES (yellow phosphor resin area). Contact may cause damage to the emitter Optics and reflectors must not be mounted in contact with the LES (yellow phosphor resin area). STANDARD TEST CONDITIONS Unless otherwise stated, LED emitter testing is performed at the nominal drive current.
