We believe the U.S. DOE SSL Program’s position on CCT and its influence regarding melatonin suppression is unintentionally misstated in this article. The article reports that a recommendation for selecting outdoor lighting of CCT < 3000 K to reduce possible melatonin suppression was supported by measurements of commercially available products by the SSL Program. In fact, the SSL Program has gone to great lengths to demonstrate the overall limitations of using CCT as a control measure for spectral content and related downstream effects, both in the cited FAQ and in numerous presentations and other materials.

澄清 2019 年 2 月 19 日 LEUKOS 文章，“大都市商业商业区外部照明可能抑制褪黑激素产生的估计”。

我们认为美国能源部 SSL 计划在 CCT 上的立场及其对褪黑激素抑制的影响在本文中无意中被误述。该文章报告说，选择 CCT < 3000 K 的户外照明以减少可能的褪黑激素抑制的建议得到了 SSL 计划对市售产品的测量的支持。事实上，SSL 计划已在引用的常见问题解答和众多演示文稿和其他材料中竭尽全力证明使用 CCT 作为频谱内容和相关下游效应的控制措施的总体局限性。
