Description
The TELUX series is a clear, non diffused LED for
high end applications where supreme luminous flux is
required.
It is designed in an industry standard 7.62 mm square
package utilizing highly developed (AS) AllnGaP
technology.
The supreme heat dissipation of TELUX allows ap-
plications at high ambient temperatures.
All packing units are binned for luminous flux and color
to achieve best homogenous light appearance in ap-			16 012
plication.
