LM-79 Scope
Does not standardize report format or content Can be just spatial (BUG) or just spectral (CCT) Manufacturers often unaware data is incom lete
o Reports generally dont indicate make/model info for LEDs integrated into lamp or luminaire
ou e use u n eva uat ng su m tte -80, uttest lab probably not able to determine
-wouldnt necessarily give positive identification
o Reports may include off-state power draw if requested

LM-79 Content
Absolute and relative photometry methods do not work for SSL products []LED lamp sources are not designed to beremove rom e um na re.
o Absolute photometry required due to significantde endence on thermal mana ement
Hence the heat sinks often visible on LEDproducts
No standard means of determining/using rated lamp lumens for LED sources

Product Groups/Families
So test every possible variation?... different correlated color temperatures (CCTs),ENERGY STAR will allow those products to begroupe oge er, so ong as epackage(s)/module(s)/array(s), drive current,
electronics, and thermal management are otherwiseidentical. At a minimum, manufacturer must submit oneset of LM-80, In-situ Temperature Measurement Test
