However, we do not yet know to what extent such devices will become viable in the future as a replacement for existing high efficiency sources; issues such as manufacturability, cost and temperature stability must be addressed. Until these issues are sufficiently answered within the lighting industry, replacement costs and procedures will remain a reasonable concern to commercial purchasers.
Even if today’s SSL performance results are as good as the industry ever produces, a wide range of applications can be satisfied already. With performance increases actually coming at a surprising pace, and with anticipated reductions in manufacturing costs, LEDs certainly appear to be a major light source of the future.
