FIXTURE ORIENTATION AND LOCATION

The Alien 02 Spot is designed to be attache d to a Mounting Arm. These are
available in varying lengths. This mounting arm may be used as a pedestal, mounted
on a wall, or from a ceiling and shall be attached to a surface using 6 mm (1/4 in.)
mounting hardware (not supplied).

Note that the cables that connect the Alien 02 Spot to the 150W Single Base are 1
metre long. If the distance b etween the two fi xtu res is t o be great er you can or der a
cable extension kit to extend the distance up to a total of 16 metres. Keep these
relative distances in mind when positioning your fixtures.

2

Do not locate the Alien 02 Spot luminaire in an unventilated space. Install the
fixture in a location where it is:

• at least 0.5 meters (20 inches) away from the surface to be illuminated,

• at least 1 meter away from any combustible materials, and

• away from accidental public contact.

ENS OPTIONS

The following lenses are available for t he Alien 02 Spot luminaire:
70° diffuser lens: The 70° diffuser lens is standard. It provides a symmetric 70°

field. It installs with the rough side out, away from the lamp.
36° Fresnel lens: The optional Fresnel lens provides a symmetric 36° field. It

installs with the ridges out, away from the lamp.
90° x 70° beam shaper lens: The optional beam shaper provides an asymmetric

90° by 70° field. It installs with the ridges faci ng out, and may be turned as desir e d;
the ridges are parallel with the short axis of the field. This lens is lighter and more
fragile than the others: be extra careful when installing the beam shaper lens and

tighten the rubber washers just enough to exert light pressure.

Micro lens diffuser: The Micro lens diffuser provides a very flat field and
improved efficiency compa red to the st andard optical co nfigu ratio n. It can be us ed
in short throw applications where exact ev enness is required. Th e estimated sp read
angle is 60 degrees.

CHANGING THE LENS

Lens installation requires 2.5 and 3 mm Allen wrenches.

OPTIMIZING LAMP ALIGNMENT

The lamp alignment is set at the
factory. If, the light distribution is
uneven, lamp alignment may be
adjusted as follows. A 2.5 mm Allen
wrench and a Phillips screwdriver is
required.

1 Disconnect the fixture from AC

power supply and allow the lamp to
cool for 15 minutes.

2 Remove the lamp cover at the back of

the fixture using a 2.5 mm Allen
wrench.

3 The three sprung screws on the

lamp holder are used for lamp
adjustment. Switch on the Alien
02 Spot and allow it to reset.

4 Using either a controller or the

control panel, strike the lamp and
focus the light on a flat surface.

5 Center the hot -spot (the br ightest

part of the beam) by turning the 3
adjustment screws. Turn one
screw at a time to drag the hot­spot diagonally across the
projected image. If there is no hot-spot, adjust the lamp until the light is even.

6 T o re d uce a ho t-spo t, p ull the lam p in by tu rning all three screws clockwise 1/4-tu rn

at a time until the light is evenly distributed.

7 If the light is brighter around the edge than it is in the center, or if light output is

low, the lamp is too far back in the reflector. “Push” the lamp out by turning the
screws counterclockwise 1/4-turn at a time until the light is bright and evenly
distributed.

8 Replace the lamp cover.
