Welcome to the Lamp Spectral Data Base for Domestic and Public use
This spectral data base includes several types of artificial lighting: public, domestic and light therapy. It contains data such as : Lamp Spectral Power Distribution (see data sheet), amount of blue in the spectrum of the lamp (%Blue), the correlated color temperature (CCT), the lumens / watt (Lum / W) and 3 new indices to characterize lamp spectrum : Melatonin Suppression Index (MSI), Star Light index (SLI) and Induced photosynthesis Index (IPI).

Where do the indices come from?
MSI, IPI & SLI indices were defined in a paper by Martin Aubé, Johanne Roby and Miroslav Kocifaj in 2013. To learn more about these indices, have a look at the article.

- MSI - Melatonin suppression index
- IPI - Induced photosynthesis index
- SLI - Star light index
- Percentage of blue light
