Frequently Asked Questions

Q: What colors are available for the 3W high power LED chip beads?

A: These LED chip beads are available in a wide range of colors: Warm White, White, Red, Blue, Green, Orange, Yellow, Pink, UV, and RGB. This makes them highly versatile for all types of DIY lighting and decorative projects.

Q: Do I need a driver or constant current source to use these LED beads?

A: Yes. Because these are high-power LED chips operating at 2.2–3.6V and 500–700mA, it is strongly recommended to use a constant current LED driver to ensure stable performance and prevent damage from over-current.

Q: Is the 20mm Star PCB heatsink included in the pack?

A: Yes, each pack includes 20mm Star PCB heatsink boards alongside the LED chip beads. It is still recommended to mount the PCB onto an additional aluminum heatsink for high-power continuous-use applications to maintain optimal operating temperatures.

Q: Are these LED beads suitable for outdoor use?

A: The LED chip beads themselves are suitable for outdoor lighting applications such as landscape, billboard, and advertising lighting. However, when installing outdoors, ensure they are housed in a weather-resistant enclosure to protect against moisture and dust.
