Complete 2026 546 Oval LED Diode Specification List | HLX LED Official
Date：
2026-06-11
📋 Quick Overview
This page shares the official, 1000-hour aging test verified 546 Oval LED Diode Specification List directly released by Shenzhen Highlight Electronics Co., Ltd. (hlx-led.com), with no hidden or modified parameters for unqualified products.
Basic Definition of 546 Oval LED Diode Specification List
546 Oval LED Diode Specification List is a full document of standardized parameters for 5.4*6mm oval through-hole LEDs. This official spec list is generated based on real production test data of HLX 546 oval LED products, instead of theoretical simulation values. In practice, over 37% of product failure cases we encountered in 2025 come from mismatched parameters from non-verified third-party spec lists.
The industry consensus from 2026 Global LED Components Association shows that using factory-official specification lists reduces electronic project rework rate by 42% on average. Below is the 4-step guide to read this spec list correctly:
- Confirm nominal forward voltage and forward current first to match your driving circuit design
- Check luminous intensity and viewing angle to confirm alignment with your application scenario brightness requirement
- Verify operating and storage temperature range for products used in harsh outdoor or automotive environments
- Cross reference dimensional tolerance data with your PCB layout and casing design files

Q: What standard parameters are included in this official 546 Oval LED Diode Specification List?
A: The full list covers 12+ core parameter categories: electrical performance, luminous performance, mechanical dimensions, solderability requirements, anti-vibration performance, ESD tolerance, RoHS/REACH compliance data, and full reliability test records.
Q: How is HLX’s 546 Oval LED Diode Specification List different from generic public versions?
A: All parameters on HLX official list are derived from 100% on-line testing of mass production components, with ±5% data deviation allowed, while generic public spec lists usually use theoretical values with up to 30% actual deviation in real batch production.
| Parameter Category | HLX Standard 546 Oval LED (2026 Test Data) | Generic Market 546 Oval LED |
|---|---|---|
| Forward Voltage (@20mA) | 2.0~2.2V | 1.8~2.5V |
| Max Allowable Forward Current | 30mA | 25mA |
| Luminous Intensity | 800~1200mcd | 300~800mcd |
| Viewing Angle | 30° | 20°~45° |
| Operating Temperature Range | -40℃ ~ +85℃ | -20℃ ~ +70℃ |
| Dimension Tolerance | ±0.1mm | ±0.3mm |
Actual 1000-hour continuous aging test conducted by HLX in-house R&D lab in Q1 2026 confirms that our standard 546 oval LED maintains 97% of initial luminous flux after working at 25mA, 60℃ ambient temperature.
Covered Color Options in 2026 546 Oval LED Diode Specification List
The full official spec list includes 12 commonly used color variants with independent test data for each, no generalized shared parameter sheet for all colors. From real case studies, 62% of our clients choose red, yellow, green and blue 546 oval LEDs for indicator use cases on industrial control panels.
Q: Are high CRI white 546 oval LEDs included in this specification list?
A: Yes, we have 3000K, 4000K and 6500K high CRI (≥80) white 546 oval LED variants, all with corresponding spectrum test data attached in the full specification list for reference.
Q: Do you provide high brightness customized color parameters in the spec list on request?
A: Yes, for projects with minimum order quantity over 5k pieces, we can release a customized exclusive 546 Oval LED Diode Specification List with your required specific color temperature, dominant wavelength and brightness binning requirements.
Matching Application Scenarios for 546 Oval LED Specs
Parameters listed in 546 Oval LED Diode Specification List are calibrated to meet the strict requirements of high reliability scenarios, not only for low-end consumer electronics products. In practice, our 546 oval LEDs have been used by over 200 industrial control clients across 47 countries up to 2026.
Q: Can 546 Oval LEDs with this spec list be used for automotive dashboard indicators?
A: Yes, the -40℃ to +85℃ operating temperature range meets most automotive interior indicator requirements, and all ESD parameters in the spec list follow AEC-Q101 equivalent testing standards.
Q: Is 546 Oval LED suitable for outdoor high-brightness signage projects?
A: The high brightness 1000~1200mcd variant in the spec list can be used for outdoor signage with proper anti-UV encapsulation treatment, to maintain stable performance for 50000+ hours of service life.
