As the canbus resistor’s heat of the old style lamp should be conducted to PCB first, then be transferred to
heat-sink block for heat dissipation, so the lamp should bear a heavy heat flow. While the canbus resistor and PCB
of the new style lamp are designed apart, in this case the heat of the canbus resistor will be transferred to the heat-sink block directly and only the heat which hasn’t dissipated will remain on the lamp. Therefore, the new
style lamps bear much less heat and will be of more stability and longer time use accordingly.
