Competitor Claims of 2 and 3 year – 18000 to 27000 lamp life:

All UV-C lamps begin depreciating in UV output over time, though they will continue to operate for extended periods. At 9000 hours use the Lumalier/Philips lamp will not have depreciated more than 20% and this depreciation is calculated into the initial design of Lumalier equipment for peak efficiency throughout the suggested 9000 hour life of the lamp. Competitors claiming longer lamp life allow for extreme depreciation greatly reducing the effectiveness of the system.
