General information of STRADA-IP-2X6-product assembly. The following instructions should be observed before using product. To ensure reliable assembly, STRADA-IP-2X6 fastening materials (heat sink, screw) need to be suitable for lens attachment.


  • Cable holes and screw thread holes must be done before lens assembly
  • After cable holes and threaded screw holes are machined, ensure that anodized heat sink surface is even
  • Correct thickness of the PCB is 1.6 mm
  • Screw thread hole accuracy is +-0.1 mm (yellow arrow in picture)
  • Screw vertical straightness tolerance is +-⊥0.1 mm A

  • STRADA-IP-2X6 lens attachment screws are of type M3. (DIN 7985, ISO 7045/ISO 14583 TX)
  • Countersunk screw is not allowed
  • Self-tapping screws are not recommended
  • Maximum tightening torque of the screws is 0,6 Nm

2x6 screw requirements

Differing from other STRADA-IP-2X6 lenses, the CS14145_STRADA-IP-2X6-DWC-90 module needs countersunk screws of type M3 (DIN 965) for fastening the PCB to heat sink.

Please note: LEDiL recommends the use of the M3 nylon washers (DIN 125 / ISO 7089) below fastening screws on our STRADA-IP-2X6 modules to minimize stresses induced by torqueing of the screws.   Like all PMMA lenses STRADA-IP-2X6 is also prone to environmental stress cracking. Please make sure that chemicals used in the fixture manufacturing do not cause stress cracking risk with PMMA.
