Understanding LED Tape and Drivers
PowerLed Tape Range We are able to provide you a range of solutions to meet your needs • 4 IP ratings (IP20, IP65, IP67 and IP68). • A range of wattages from 4.32 ~ 20W. • 4 colour temps (2500, 3000, 4000 and 6000K).
CRI Colour rendering index is the measurement of a light sources ability to accurately recreate colours
RA >80
(Colours R1-14 below). It is a dimensionless number between 0 and 100 – with 100 being a 100% replication of colour according to CIE Standards. An average
value is used and referred to as ‘Ra’.
LED Binning Binning refers to the sorting of LED by measuring certain attributes, such as voltage, colour temperature and brightness. These
Cut Points Where you have to cut the tape you should only use the cut points indicated on the tape and with a small amount of silicone sealant, to reseal against ingress & retain the IP rating of the product. Strips should only be cut at the cut points illustrated on the tape.
characteristics ensure that LEDs used in the production of LED flexible tape are consistent with the production specification.
ANSI LEDs are sorted using the ANSI (American National Standards Institute), this defines the chromatic deviations using the McAdam ellipse. This measurement determines the visible differences to each led in relation to the naked eye.
