This side-by-side comparison uses original photographs and recorded measurements to examine how the EB and OSRAM H11 LEDr samples differ from packaging and lamp construction through to beam distribution, temperature and operating noise. In the recorded results, EB had a smaller distance between opposing LED emitting surfaces, higher illuminance at the right-side points and a lower emitting-surface temperature, while OSRAM produced more centre-left illumination, a lower B50L value and less fan noise.
