LED strip lights – Top considerations before selecting – What determines LED quality?
IES LM-79 aspects: WHITE light in phosphor based LED sources is a result of a mixture of many attributes. The final colour consistency and spectral power (outputs) are achieved by binning techniques of the manufacturers.
The location, shape and size of these bins have a rough conformance to the varying orientation and sizes of MacAdam ellipses.
Binning and SDCM values and information are more important in point source (chip) LED that they are in LINEAR formation (LED strips)
3-step MacAdam and 5 step MacAdam for comparison
IES TM-30-15 aspects: more accurate quantification of the “QUALITY” of light produced by LED sources become increasingly necessary with availability of wide range LED sources and Full Spectrum options, which requires more detailed colorimetry tools and structure.
- Fidelity (Rf)
- Gamut (Rg)
- colour vector graphics
NOTE: high CRI does not necessarily ensures high colour fidelity!

DLS NOMENCLATURE for FLEXI LED strips:
Dome Lighting Systems LED strips are selected to achieve over 180lm/W (at cri>80) or 135lm/W with high cri (93) and high Rf and Rg to suit all applications at highest energy eficiency.
Typical features of FLEXLED range include:
Double Copper PCB for improved electrical, Thermal conductivity
3M backing adhesive tape as standard
One Bin in 3 SDCM as standard, one BIN in 1 SDCM available as an option.
Configuration of LED strip performance can be tailored to the needs of the design.
