GENERAL INFORMATION
Thank you for your selection of one of our most effective studio luminaires, the MSL155. This high
performance luminaire should provide many years of low cost operation. The MSL155 is designed
to maximize "throw" or "punch" by collimating the light while remaining "cool" and minimizing shadows.
Unwanted spill is controlled with optional egg crates or honeycomb. The luminaire provides a mounting
slot for attaching gel frames and/ or honeycombs and egg crates. The SL series is as close as fluorescent
can come to a key light.
All PrimeTime Studio Lights are equipped with advanced reflector technology.
The MSL155 is available in standard full power (non-dimming), Voltage dimming, analog signal dimming
(0-10 volts) and full DMX -512 discrete dimming (1 luminaire per channel). This degree of availability
provides for compatibility with most current control scenarios.
The MSL155 is made of welded aluminum and powder coated in non-reflective black. Accessories are
made of aircraft alloy aluminum. Standard luminaires are equipped with detachable 10' long power
cords. Each 120 volt cord is equipped with Edison 3 prong connectors. Other voltage models are
shipped without plug unless specified. A fused power in and out receptacle is supplied for
120 volt models. Adjacent fixtures may be powered with this connector so long as the load does
not exceed 800 watts. (fig. 2) The switch controls the power to the one fixture. Power to a luminaire
is indicated when the switch is lit.
The MSL155, like most of the line, is mountable in horizontal or vertical orientation. Ordinary grip
devices allow stand mounting as well.
For instructions on dimming models see dimming addendum.

The control panel is shown in fig. 2. The "FUL" panel configuration is the same as that of the voltage
dimming model. A label containing the product information, including voltage and wattage can be
found there.
Figure 3 indicates the features of the luminaire.They are:
1. Fresnel reflector exhibits 95% specular reflectance. Spectral response is unchanged over the visible
range.
2. The MSL155 is fitted with one twin tube 55 watt studio lamp, in several colors and CRI. See table 1.
3. Lamp retainers locate and hold lamps securely. See "Lamp Installation".
4. Heavy duty adjustment knobs provide for altitude pointing.
5.Yoke or bale suspends luminaire and allows azimuth pointing.
6. Rotation about this axis allows hemispherical aiming.
7. Control panel, including switch and power connection. See fig 4.
8. Mounting slot retains gel frames, honeycombs and lens.
9. Lampholders. See "Lamp Installation". CAUTION: Never remove or install lamps with power on.

INSTALLATION:
Remove the luminaire from the shipping carton and inspect for any damage during shipping.
If attenuators are ordered they may be installed in the aperture. If so, loosen the accessory
slot cover retaining screws and slide the cover back to expose the slot. Remove the accessory
to install the lamps which are shipped separately. see figure 4. Check the base of each
lamp to insure that you have the correct lamp color and CRI. See Table 1 for available lamps.

After determining that the lamps are correct, install the lamps by gently inserting one side
of the lamp into the lamp clip. Then slide the base of the lamp into the socket while
aligning the four pins with the holes. A "snap" is felt when fully plugged in. See fig 3.
Caution: never remove or install lamps with active power to sockets as arcing can occur.
Always turn off the switch or unplug the power cable at the rear of the fixture housing.
When changing lamps allow a few minutes for cooling. Caution should be taken whether
installing or removing as glass chards could occur.
When the lamps are installed, it is advisable to
bench test each fixture. Plug the the power cord
in one luminaire and turn the switch on the
control panel ( fig 2 ). The switch should be lighted
if the ballast has power. The lamps should start.
Full intensity and correct color will be attained in
about 5 to10 minutes. Next, the hanging means
should be mounted on the yoke (fig 5 ) with a 1/2"
bolt supplied with the "C" clamp and or stem. If
vertical mounting is desired, the hanger or stem
should be attached on one end of the yoke brace. If daisy chain power is desired, up to
a total string wattage up to 800 watts, use of the "power out" receptacle. in figure (2).
Never install any lamp except twin tube Dulux or Biax with a
rating of 55 watts. Improper lamp installation will produce poor
color and will shorten ballast life. Avoid mounting over people
without a lens of some type (neutral filter) in case of non-
passive lamp failure. With the stems and "C"clamps attached,
hang each assembly in the desired location on the 2" pipe
grid or other qualified hanging system. Immediately add a
fig 5 safety cable as per fig. ( 5 )

The mirrored surface of this lighting product has the highest specular reflectance of
any commercially available material. With proper care it should perform well for
many years.
Fingerprints show up clearly and should be avoided. Dust adhering to the reflective
surface shows, as well. In the event that soiling should occur, the reflector can be
cleaned with little effort. It is best to start with a feather duster.
The clear coating of the reflective surface is chemically resistant and relatively
tough but can be scratched by rubbing dusty grit causing marks. The effect is
mostly cosmetic but should be avoided, especially for open fixtures. The best
cleaners are those which leave no residue. Glass cleaners work well, as do very
dilute solutions of hand dish wash detergents (1 drop/quart). Solvents stronger
than iso-propyl alcohol should never be used.
Never use paper towels or tissues as these materials are made from wood and will
cause scratches. Only soft cotton cloths should be used to wipe the surface. Use
single strokes along the long axis of the reflector. Never use an orbital motion. The
idea is that linear scratches don’t show as much. Most scratches are caused by
dust and dirt being rubbed into the surface. Before wetting the mirror surface,
remove as much dust as possible using a feather duster or compressed air. Cloth
diapers or soft, (well used) terry cloth works best. Never use spray cleaners like
Formula 409, as these compounds leave residue. Spray on glass and mirror
cleaners work best. If you have any questions call (214)-393-5998.

If the luminaire will not strike, first determinme if power is available to the switch.
If the switch glows, there is power. Units older than 5 years may have plain switches.
In this case, check for power at the outlets on the light and source. If the luminaire
does not strike, the lamps may not be seated. Sometimes lamps are not seatedl
fully into the socket. Never try to replace lamp wth the fixture power on. This light
is rated to start at 50 degrees F or below. High temperatures affect lamp
colors and cause shortened ballast life. If the light flashes but won't stay on,
there may be a loose wire or bad electnonic ballast. Consult Fatory if the
luminaire is non-responsive. (214)-393-5998
