Custom 40mm PCB CRI90 high-output LED strip solution with 4300–6600 lm/m, short cutting lengths and sample testing for linear lighting projects.
Project Overview
A European lighting manufacturer contacted HST Light looking for a high-output LED strip solution for a linear lighting application. The customer had several clear technical requirements:
- DC24V
- 40mm wide PCB
- CRI Ra90 minimum
- 4000K
- High luminous output
- Short cutting length
- Sample testing before moving forward
Customer Requirements
The main concerns were whether a 40mm PCB could be customized, whether the strip could maintain CRI Ra90, the minimum cutting length, and sample availability. HST Light prepared two technical options for evaluation.
Solution 1: 540 LEDs/m High-Efficiency LED Strip
- Voltage: DC24V
- LED Type: SMD2835
- LED Density: 540 LEDs/m
- PCB Width: 40mm
- Power: 23W/m
- Luminous Flux: Approx. 4300 lm/m
- CCT: 4000K
- CRI: Ra90
- IP Rating: IP20
- Cutting Length: Approx. 16.6mm
- Cable: Both ends with cables
- Standard Packing: 5m/reel
This version is suitable for applications that require high brightness but still need to control power consumption and thermal load.
Solution 2: 810 LEDs/m Ultra-High Output LED Strip
- Voltage: DC24V
- LED Type: SMD2835
- LED Density: 810 LEDs/m
- PCB Width: 40mm
- Power: 35W/m
- Luminous Flux: Approx. 6600 lm/m
- CCT: 4000K
- CRI: Ra90
- IP Rating: IP20
- Cutting Length: Approx. 11.1mm
- Cable: Both ends with cables
- Standard Packing: 5m/reel
This version provides significantly higher lumen output and allows more flexible cutting for applications with tighter dimensional requirements.
How We Helped the Customer Choose
Choose 540 LEDs/m if the priority is lower power consumption, better balance between brightness and cost, easier thermal management, or high output without the maximum power level.
Choose 810 LEDs/m if the priority is maximum lumen output, shorter cutting distance, higher illumination levels, or more flexibility for short-section installation.
For most linear lighting applications, the 540 LEDs/m version provides a practical balance between efficiency, output and power consumption.
Why PCB Width Matters
For high-power LED strips, PCB width affects heat dissipation, copper area, current carrying capacity, voltage stability, and long-term reliability. When power increases to 23W/m or 35W/m, thermal management becomes especially important, and a properly designed aluminum profile should be considered together with the strip specification.
Why CRI90 Can Affect Luminous Efficiency
Higher CRI LEDs usually provide better color rendering, but luminous efficacy may be reduced compared with lower-CRI versions. A high-output CRI90 strip must balance LED efficiency, power, heat generation, PCB structure, lumen output and color quality.
Sample Testing Before Production
For customized or high-output projects, sample testing is strongly recommended. The customer can verify actual brightness, color temperature, CRI, power consumption, heat performance, cutting flexibility, installation compatibility, and aluminum profile matching.
