Notes:
1. For the product model without a suffix such as KC24H-300R, this product is a 4-pin product without the functions of analogue dimming and PWM dimming.
2. For the product model with a suffix X1 such as KC24H-300RX1, this product is a 5-pin product only with the function of analogue dimming.
3. For the product model with a suffix X2 such as KC24H-300R X2, this product is a 5-pin product only with the function of PWM dimming.
4. For the product model with a suffix X3 such as KC24H-300R X3, this product is a 6-pin product with the functions of analogue dimming and PWM dimming.
