In practice, the 800-lumen target is achieved with a few additional parts and with an increased thermal load in the system. For this part of the exercise, we are assuming a higher junction temperature of 85 °c. The two cost-effective leDs for this bulb are the Xp-e Hew and the CXA2011. The PCT is again configured to illustrate numbers of LEDs, system lumens, system power and efficacy.
