Frequently Asked Questions

Q: What size LED chip is compatible with this 23×10mm aluminum heatsink?

A: This heatsink is designed for 1W LED chips or single-chip LEDs. The LED is mounted onto the cross-section of the heatsink, with a transverse hole spacing of 16.6mm, making it ideal for standard 1W LED modules used in household lamps.

Q: Is this heatsink suitable for outdoor or high-humidity environments?

A: This heatsink features a natural aluminum finish with no additional coating. It is primarily intended for indoor household lamp applications. For outdoor use, ensure the fixture provides adequate protection from moisture to prevent corrosion over time.

Q: Do I need thermal paste to attach the LED to this heatsink?

A: For best thermal performance, it is recommended to apply a thin layer of thermal conductive adhesive or thermal paste between the LED chip and the heatsink surface. This maximizes contact and improves heat transfer efficiency.

Q: How many heatsinks are included in one order?

A: Each order includes 1 × aluminum LED heatsink radiator (23×10mm). You can order multiple units as needed for your project.
