FAQ (Frequently Asked Questions)

Q1: What is the thermal conductivity of this aluminum PCB?
A: The thermal conductivity rate is 2.0 W/m.k. This ensures efficient heat transfer away from the high-power Cree XHP70 chip, which is crucial for maintaining brightness and extending the LED's lifespan.

Q2: Can I drive this PCB directly with a 12V power supply?
A: No. The Cree XHP70 chip on this board operates at a forward voltage of approximately 6V. You must use a constant current LED driver or a buck converter suitable for 6V operation to prevent damaging the chip. Do not connect it directly to a voltage source higher than its rating without current regulation.

Q3: What is the maximum current this board can handle?
A: The board is designed to handle up to 4.8A at 6V. However, running at maximum current requires adequate heatsinking. We recommend using a proper heatsink and thermal paste to ensure the aluminum base can dissipate the heat effectively.

Q4: Is the LED chip pre-soldered to the board?
A: Yes, the Cree XHP70 chip comes pre-mounted and soldered onto the 40mm aluminum PCB, ready for integration into your lighting fixture. You simply need to solder wires to the VIN and GND pads.

Q5: Do you offer different color temperatures?
A: This specific listing is for the 6500K Cool White version. If you require Warm White (3000K) or Neutral White (4000K), please contact our sales team for availability and custom ordering options.
