DURASTRIP PRO uses "copper shielded" technology (complété copper coating on the circuit on both sides of the support) designed by our Research and Development Laboratory: the increased quantity of copper improves thermal management and ensures a longer life. DURASTRIP PRO are produced with a dual circuit substrate: the power distributed to every circuit is less, the température is halved and the risk of power failures is eliminated. Using LED 3528 limits the colour shifting effect on the beam émission angles.
