XLamp CXB2540

Second Generation of CXA LED Arrays

The XLamp CXB2540 LED Array is a member of the second generation of the CXA family that delivers up to 33% higher efficacy than the first generation in the same LES. The higher performance CXA2 LED Arrays allow lighting manufacturers to achieve the same or better performance with a smaller LES, enabling a radical reduction in system size and cost. CXA2 LED Arrays share the same physical design as the previous generation, allowing lighting manufacturers to leverage the existing optical, mechanical and electrical design elements to accelerate time to market without additional cost.
