# §429.57. General service lamps.

- (a) **Determination of represented value.** Manufacturers must determine represented values, which includes certified ratings, for each basic model of general service lamp in accordance with following sampling provisions.
  - (1) The requirements of [§ 429.11](/cfr/10/429.11.md) are applicable to general service lamps, and
  - (2) For general service incandescent lamps, use [§ 429.66(a)](/cfr/10/429.66.md?p=a);
  - (3) For compact fluorescent lamps, use [§ 429.35(a)](/cfr/10/429.35.md?p=a);
  - (4) For integrated LED lamps, use [§ 429.56(a)](/cfr/10/429.56.md?p=a);
  - (5) For other incandescent lamps, use [§ 429.66(a)](/cfr/10/429.66.md?p=a);
  - (6) For other fluorescent lamps, use [§ 429.35(a)](/cfr/10/429.35.md?p=a); and
  - (7) For OLED lamps and non-integrated LED lamps, use [§ 429.56(a)](/cfr/10/429.56.md?p=a).
- (b) **Certification reports.**
  - (1) The requirements of [§ 429.12](/cfr/10/429.12.md) are applicable to general service lamps;

For non-integrated LED lamps, the certification report must also include the input voltage and current used for testing.
- (c) **Rounding requirements.**
  - (1) **Round input power to the nearest tenth of a watt.**
  - (2) **Round initial lumen output to three significant digits.**
  - (3) **Round lamp efficacy to the nearest tenth of a lumen per watt.**
