They operate at 2.2–3.6V and 500–700mA for full 3W output.\u003c\/p\u003e\n\u003ch4\u003eQ: Do these LED chips come with heatsinks attached?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: What colors are available for these 3W LED chip emitters?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: What type of driver is recommended for these high power LED chips?\u003c\/h4\u003e\n\u003cp\u003eA: A constant-current LED driver matched to the chip's 500–700mA current range and 2.2–3.6V voltage specification is recommended.
