Tips for an effective use
Surrounding light
An optimal result with the best contrast can be achieved in dark or dimmed surroundings. Daylight or
direct sunlight are many times lighter then artificial lighting and will therefore leave the projection
colour faded. Within rooms the result can be improved by avoiding to point spotlights or radiators on
to the projection area.
Material and colour of the projection area
The projection lamp BIL allows for projections on to a surface as well as through transparent surfaces.
The image quality greatly depends on the properties of the projection area. Therefore areas to be
projected on need to be non-transparent and should be light in colour. Best results will be gained on
matt white walls or flooring. Articles on display, parts of the decoration or furniture can be used as a
projection surface. However, mirrors, mirrored and or reflective metal surfaces are not suitable for this
purpose. Coloured surfaces will have an influence on the colours being projected.
In order to project through a surface (also called ‘rear projections’) all half-transparent materials, e. g.
calendered glass, frosted glass, transparent materials or paper can make suitable surfaces. For a rear
projection, the BIL is positioned behind the projection area (see Fig. 2). The projected motif is then
visible at both the front and rear side of the area.

Distance between BIL and the projection surface
As a general rule, an increase in the distance between the projector and the projection surface
increases the size of the projection, whereas both contrast and lightness will decrease. Under normal
room-light conditions, BIL is suitable for projections at a close-up range, i.e. 0.5 to 3.5 mtrs.
In darkness, greater distances are possible. The size of the projection can be influenced by the
distance to the projection surface. Therefore we recommend you to test the projection size prior to
mounting the projection lamp. The built-in standard lens with its 40 mm focal distance can be
exchanged by a telephoto lens with a 85 mm focal distance, in order to customise projection sizes
and distance. The 85 mm telephoto lens is available as an optional accessory. For further information
on this, please contact our customer support service.

Mounting
Considerations before mounting
1. The mounting should be done by a qualified specialist.
2. Take particular care that cabling is given enough slack!
3. Use appropriate fixings that are suitable for the intended mounting area! The enclosed screws
and universal rawlplugs are suitable for fixing the transformer securely to solid ceilings and are
not suitable for use with other construction materials.
4. The transformer housing is designed to take pan head screws of 4 – 5 mm in diameter
(supplied in delivery). Do not use counter sunk screws, as you could damage the housing.
5. Prior to mounting, check whether the location is suitable for projection, and if the distance to the
projection area allows for the intended result. You will find details to help you find the right choice
of location in the previous chapter „Tips for an effective use“.
6. The projection lamp may be set up in a vertical/ horizontal position, or at an angel. The deflection
mirror redirects the projection at an angel of 90° and can be rotated by 360°. By using the
deflection mirror, a lamp that has been mounted vertically can still project in horizontal direction,
e.g. on to a wall (please see the chapter ‚Setup and use’).
7. The maximum permitted length for the suspending ropes is 2 metres. The ropes that are included
in the delivery must not be replaced by longer ones.
8. Never cut the suspending ropes. The ropes’ length can easily be adjusted by merely pulling them
backwards and winding them up inside the transformer casing (see Fig. 6 and 7).
9. Connecting, crossing or putting knots between the left and right suspending rope may lead to a
short circuit (shutdown). This will not damage the device, but lead to a shutdown of the projection
lamp. Therefore, please make sure that the suspending ropes are carefully installed and
unconnected.
10. Avoid sharply bending or twisting the suspending rope, as both may not be reversible later.

Mounting the transformer on the ceiling
1. Unroll the suspending cables and put them on the ground flat and parallel.
2. Remove the cover plate from the transformer housing by lifting it with little force (please see Fig.
4). The lid is held in place by four barbed hooks. Slide the lid over the suspending ropes until it
rests on the projection lamp.
3. Lay down the projection lamp on a table or ladder underneath the mounting position, so that you
can reach the ceiling without having to lift the projection lamp. You may need a second person to
support you if the ceiling is very high.
4. Hold the transformer housing to the ceiling and mark the positions for the two screws. Make sure
that the connecting wire enters the housing through the intended opening (see Fig. 5).
5. Put the transformer housing to the side and install the drill holes and rawlplugs at the ceiling.
6. Screw the transformer housing to the ceiling. Check that it is mounted safely and tightly.
7. Connect the wires free of stress to the double luster terminal at the transformer housing.
8. Attach the luster terminal to the provided retaining clip (see Fig. 5, magnification underneath).

Positioning the suspending ropes at the required length
1. One after the other, the left and right suspending ropes need to be adjusted at the same length (in
small steps, one by one). Make sure that the ropes are not sharpely bent or clamped.
2. Push the cable tensioner upwards „1“ (see Fig. 7 – bottom) and pull the suspension rope through
the tensioner as far as necessary. Upon releasing the cable tensioner, the suspension rope will
automatically be fixed. At this stage, the rope must not be coiled up inside the rope chamber.
3. Wind up any excess rope around two fingers (see Fig. 6) and put the coiled up rope into
the cable chamber next to the cable tensioner.
4. Repeat this procedure with the second suspension rope. Minor length difference of 10 to 40 mm
may be corrected after the transformer housing has been closed.
5. As soon as the suspending ropes have been adjusted to their appropriate length, put the lid on
the transformer housing and make sure it clicks on properly on both sides.
6. Correct any rope length differences by pushing the cable tensioner upwards and sliding the
suspending rope into or out of the transformer housing (see Fig. 7).

Setup and use
Switch on the projection lamp when the transformer housing has been closed and the lighting element
has been inserted. The projection can only be adjusted with the lamp switched on. Do not touch the
lighting element when the lamp is switched on, as it becomes very hot.
Adjusting the lamp
The projection lamp may be set up in a vertical/ horizontal position, or at an angel. When adjusting the
lamp, it needs to be synchronised with the room’s design and illumination concept. In order to change
the angle of the dismounted projection lamp, turn both cable retainers into the desired position (see
Fig. 8).
Fig . 8: Adjusting the lamp
Inserting the deflection mirror
The deflection mirror redirects the projection at an angle of 90° and can be rotated by 360°. By using
the deflection mirror, a lamp that has been mounted vertically can project in the horizontal direction,
e.g. on to a wall.
1. Set the mirror’s retainer ring in front of the projection lamp’s beam at an angle.
2. Push the retainer ring downwards, until it clicks in firmly.
3. Turn the deflection mirror around the lamp’s longitudinal axis, until the projection appears at the
right spot.
