Dark Sky Commercial Lighting Products

First-Dark-Sky-City (FDSC) Recommendations for roadway and commercial lighting

Come to FDSC for the best in dark skies!

These are some specific fixtures that offer options that provide the best dark sky protection – FDSC Grade AAA or AA – for general roadway and commercial lighting applications. All of these fixtures are fully shielded, allow specification of the best (lowest impact) “narrowband” or “direct emission” amber LED (NBA LED).

Confirm spectrum
Despite the common use of terms in product literature like “dark sky friendly,” “turtle friendly,” and even “IDA Certified” or “IDA Dark Sky Approved,” lighting users or specifiers seeking low-impact lighting must do their own due-diligence and not rely on manufacturers’ claims. The terminology used in the product specifications (e.g. “2K 580nm,” “AMB,” and “AM”) can be ambiguous and could indicate NBA LED, PCA LED, or LED with other spectral characteristics. The manufacturers listed below have provided the indicated fixtures with NBA LED and PCA LED, but we caution that if you order these products the specific spectral characteristics must nevertheless be carefully confirmed directly with the manufacturer for each order. Confirm the desired spectrum by asking for a spectral power graph – and compare with the figures below.

For communities or lighting designers seeking the moderate dark-sky impacts of HPS-like PCA LED (or those using lowest-impact NBA LED for roadway and parking, but seeking an alternative to high-impact white LED in applications needing color rendition), click here for PCA LED products. We caution that PCA LEDs are highly variable, with spectra causing sky glow impacts from somewhat less than HPS to substantially more (see our page Lamp Spectrum and Light Pollution). To assure your product contains the PCA LED with the lower impact spectra we recommend (i.e. S/P <0.5 for FDSC Grade AA), you must work with the manufacturer to confirm the the S/P ratio. At present, HPS remains a viable technology.​

The International Dark-Sky Association offers certification that fixtures meet their standards for dark-sky quality. Such fixtures must be fully shielded and “minimize blue light,” which IDA standards implement only as a requirement that the CCT must be 3000K or less. These IDA FSA standards are equivalent to FDSC Grade C standards. The products listed below, with NBA LED and PCA LED, meet FDSC Grade AAA to FDSC Grade AA standards, and have substantially less blue (and equally as important less green) light and ~60-80% lower skyglow impacts – see our page Lamp Spectrum and Light Pollution.

The list below does not include links to products, as these change so frequently. We try to keep the links to the manufacturer’s websites current – you can go to these and look for the product names, or even search generally for the term “amber” and this may help you find their current products with amber LED options.
Kim Lighting

Kim offers direct-emission amber LEDs in many or most of their outdoor product lines. On their product “cut sheets” or catalog pages the NBA LED option is specified by selecting the “CCT” of “2K 580 nm.”
