Medium base compact fluorescent lamp
means an integrally ballasted fluorescent lamp with a medium screw base, a rated input voltage range of 115 to 130 volts, and which is designed as a direct replacement for a general service incandescent lamp; however the term does not include:
(1) any lamp that is:
(A) specifically designed to be used for special purpose applications; and
(B) unlikely to be used in general purpose applications, such as the applications described in the definition of “Federally‐regulated general service incandescent lamp” in this section; or
(2) any lamp not described in the definition of “Federally‐regulated general service incandescent lamp” in this section that is excluded by the Secretary, by rule, because the lamp is:
(A) designed for special applications; and
(B) unlikely to be used in general purpose applications.
