Installing a diffuser
Optional diffuser lenses are available from Martin to modify the
beam width (see table below and ‘Accessories’ on page 35 for
details).
The diffuser is held in place either by the included trim ring or, if
installed, by a snoot or honeycomb louver accessory.
Located close to the edge of the diffuser is a marking that gives
the diffuser’s nominal beam angle and indicates which side of
the diffuser must face outwards (see Figure 3). Note that the
marking is partially hidden under the diffuser’s silicone gasket.
Note that the nominal diffuser beam angle is for reference only.
The effective beam angle given in the table below is the beam
(half-peak) angle that you will actually obtain, depending on
which fixture you install the diffuser on.

To install an optional diffuser lens:
1. Shut down power to the fixture and allow it to cool.
2. See Figure 4. Position the diffuser A over the front of the fixture, making sure that the marking ‘ this
side out ’ close to the edge of the diffuser faces outwards, towards the front of the fixture.
3. With the cut-out channels in the silicone gasket facing outwards, align the channels in the gasket with
the drain channels at the bottom of the front ring.
4. Press the diffuser lens gasket firmly into the recess in the front ring.
5. Either place a trim ring C over the diffuser and fasten it securely with the supplied screws or install a
honeycomb louver or snoot as described in the next sections.
