Frequently Asked Questions
Q: What chip size are these 3W high power LED beads?
A: These LED chips use a 45 MIL chip size, which provides superior brightness and a longer lifespan compared to smaller chip sizes. They operate at 2.2–3.6V and 500–700mA for full 3W output.
Q: Do these LED chips come with heatsinks attached?
A: Yes — each 3W LED chip is pre-welded onto a star-shaped aluminum PCB board that acts as a built-in heatsink base, helping dissipate heat efficiently during operation. Additional external heatsinks may be used for demanding applications.
Q: What colors are available for these 3W LED chip emitters?
A: These LED beads are available in White, Warm White, Red, Blue, Green, Yellow, Orange, Pink, RGB, and UV — giving you the flexibility to choose the right color for signage, décor, grow lights, or any custom lighting project.
Q: What type of driver is recommended for these high power LED chips?
A: A constant-current LED driver matched to the chip's 500–700mA current range and 2.2–3.6V voltage specification is recommended. Using a constant-current driver helps protect the chips from overcurrent damage and ensures consistent brightness over time.
