Comparison of Different Power Ratings in Colorful LED Strip Lights

Purpose of Aging Test and Experimental Environment Description

• Test Purpose: With increasing LED strip manufacturers and intensifying price competition, most 2835 chips in current market LED strips are 0.2W. Some customers for color LED strips may opt for 0.1W chips to reduce costs when lower brightness is acceptable. This test compares 0.1W and 0.2W chips, recording data to provide effective support for color LED strip R&D.

• Tested Products: Colorful LED Strip
  • 60 LED/m LED strip using both 0.1 W and 0.2 W chips, testing red, green, blue, and yellow colors.
  • 120 LED/m LED strip using both 0.1 W and 0.2 W chips, testing red, green, blue, and yellow colors.
  • Type: SMD2835; Supplier: Smalite LED

• Test Method: For both 60LED/m and 120LED/m specifications, test using an integrating sphere and spectrophotometer to record corresponding brightness, luminous efficacy, color rendering index, color temperature, etc.

Comparative Analysis of Photovoltaic Parameters for LEDs of Different Power Ratings

• Brightness and Luminous Flux: LED strips using 0.2W chips deliver approximately 1.6–1.8 times the luminous flux of 0.1W chips, offering higher brightness suitable for scenarios requiring stronger illumination (e.g., spot lighting, decorative strips). 0.1W chips provide lower brightness, ideal for low-intensity indicators or ambient lighting (e.g., dashboard indicators, interior mood lighting).

• Luminous Efficiency and Power Consumption: 0.2W LEDs offer slightly higher luminous efficiency and superior energy efficiency, making them more economical for long-term use. 0.1 W LEDs have marginally lower luminous efficiency but consume less power overall due to their lower wattage, making them suitable for power-sensitive devices (e.g., portable electronics, automotive circuits).

• Voltage and Current: Both operate within the same voltage range (2.2-2.4V), compatible with identical power supplies. The 0.2W LED requires twice the current of the 0.1W LED (60mA vs 30mA), necessitating attention to circuit load capacity to prevent overload.

• Color Temperature and CRI: Both have very similar color temperatures and CRI ratings, offering identical light color and color rendering capabilities. They can be interchanged without altering visual effects.

Conclusion

0.1W LEDs offer a price advantage. They are suitable for low-brightness indicators, ambient lighting (e.g., automotive mood lights), indicator lights on small electronic devices, and applications where brightness requirements are low and cost is a priority.

The price of 0.2W chips is approximately 2–3 times the price of 0.1W chips. For example, in a 120-LED red light strip, using 0.1W chips saves about $0.60 per meter compared to 0.2W chips. For high-brightness applications like decorative light strips or commercial lighting, 0.2W LEDs offer higher luminous efficacy, superior brightness, and greater stability. They are suitable for prolonged use and deliver lower energy consumption while maintaining equivalent brightness.

0.2W LEDs outperform 0.1W LEDs in brightness and luminous efficacy, making them ideal for high-brightness applications. 0.1W LEDs excel in lower power consumption, suitable for low-brightness, low-power scenarios. Both maintain consistent color temperature and color rendering index (CRI). Selection should be based on specific brightness requirements and circuit conditions.
