QLSP05RG

Overview

The QLSP05RG is a discrete red LED from Quelighting Corp's Horticulture series, designed for specialized lighting applications. It features a 1411 (3528 Metric) surface-mount package with dimensions of 3.50mm x 3.20mm and a maximum height of 2.20mm. The component emits light at a peak wavelength of 623nm, falling within the 615nm to 630nm range. It operates with a typical forward voltage of 2.2V and supports a maximum current of 700mA. The device offers luminous efficiencies up to 91 lm/W and includes viewing angles of 60°, 90°, or 120°. It is RoHS3 compliant and has an MSL rating of 2A.

Feature Summary

• Specialized horticultural red emission optimized for plant growth spectra
• High luminous efficiency delivering up to 91 lumens per watt
• Versatile optical distribution with selectable beam angles
• Standardized surface-mount footprint for automated assembly

Applications

• Indoor vertical farming and controlled environment agriculture
• Plant growth promotion and photomorphogenesis systems
• Horticultural grow lights and supplemental illumination
• Scientific botanical research and phenotyping chambers

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, such as tape and reel or cut tape, as these affect handling procedures. Confirm the active lifecycle status directly with the manufacturer to ensure long-term availability. Check for any recent design changes or pinout revisions in the latest datasheet revision history before finalizing procurement specifications.

Selection Notes

Select this component when a dedicated red spectrum source is required for biological processes rather than general visibility. Ensure the thermal management design accommodates the 700mA maximum current rating to maintain stable output. Compare the available viewing angles against the optical system requirements to determine if additional lenses are necessary for uniform distribution.

Part Context

This part belongs to the QLSP05 series, which utilizes the 1411 (3528 Metric) SMD form factor. Similar variants in this family include the blue-emitting QLSP05B and white-emitting QLSP05W. These components share mechanical mounting characteristics but differ significantly in spectral output and electrical parameters based on their respective semiconductor materials.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 1411 package dimensions, 623nm peak wavelength, and 2.2V forward voltage characteristics with alternative manufacturers.
