General information to the LED beam angle, the use of diffuser and barndoors, day-
light versus bi-colour light panel version
With the Niova 600 / 900 Plus model series, the arrangement and the selection of built in
LED bulbs provides a light beam angle of approx. 45°. This is a very good compromise with
light that is not too hard for use, even at short distances (e.g. in studios and when using
lamp stand). Otherwise, the low beam angle of 45° (without diffuser) ensures that the set
cone of light provides a good light power level (Lux) even at medium and larger distances.
Information to the light characteristics of LED panels, depending to the LED beam angle:
• 30-35° beam angle:
Very hard, strongly focused light for use at large distances.
• 40-45° beam angle:
Modern and up to date, good compromise for use in the studio at short
distances (when using a diffuser) and for medium to large distances (without a diffuser), de-
pending on the maximum device output power.
•
55-60° beam angle:
Commonly used, good compromise for use in the studio and at short to
medium distances; at longer distances, powerful devices are required
•
120° beam angle:
Very soft, even and very dispersed light for illumination at a short distance;
at greater distances, very powerful devices are required.
The LED lights of the Walimex pro Niova 600 / 900 Plus series have removable diffusers and
barndoors. With daylight models (colour temperature of 5,600 Kelvin), a white and an oran-
ge diffuser comes with the scope of delivery. The light characteristics can be changed using
a diffuser. A diffuser provides even, soft light characteristics. By using the orange diffuser, you
can change the colour temperature towards a more red coloured, warmer tone. With bi-co-
lour models, the orange diffuser is not needed and not included, because the variable co-
lour temperature is generated by the use of two different LED bulbs (white light and tungsten
LEDs), stepwise between 3,200 and 5,600 Kelvin. The use of barndoors / light flaps provides
extra control over the cone of light and offers additionally versatile edge setting possibilities.
Bi Color versus Daylight models:
The LED panels of the Walimex pro Niova 600 / 900 Plus series comes in daylight and bi-co-
lour versions. Please find below a description of the features of each of the models.
Daylight Version:
A daylight LED light panel is a specialist for providing a lot of bright light with a daylight colour
temperature of 5,600 Kelvin. At this model, only daylight / white light LED bulbs are installed in
the device. The colour temperature can be affected by using an orange diffuser.
Bi Color Version:
The bi-colour models are the very modern, versatile variations of LED light panels. They have
built in half daylight / white light LED bulbs and half orange / tungsten coloured LEDs bulbs.
This allows the user to adjust the colour temperature between 3,200 and 5,600 Kelvin. At 3,200
Kelvin, only the tungsten-coloured LED bulbs are activated, at 5,600 Kelvin only the white LED
bulbs are powered on. This ensures a high variability, but results especially at 3,200 and 5,600
Kelvin, in a lower maximum illumination intensity, compared to the Daylight version with the
same power. Mixed light with a colour temperature of 3,300 to 5,500 Kelvin is created by mixing
the strengths of each kind of LED bulbs. The maximum light output is achieved at the Bi Colour
version at 4,300-4,400 Kelvin if both LED bulb types works with the maximum power. The va-
riable colour temperature allows good handling of often existing mixed light. You can also give
different emphasis to your photo and video results by using warmer or colder light.
7. Power supply
7.1 Batter power supply – installing the battery
• Switch the device off – <O><OFF> –with the ON/OFF switch (26) on the device.
• Place a sufficiently charged and compatible battery (Sony NP-F compatible; see detailed inst
-
ruction on page 47) on the backside of the led light into the battery compartment (14).
• Usually, a short clicking sound from the battery safety lock indicates that the battery has been
correctly inserted.
• Check that the battery is securely in place.
• Put batteries into both battery compartments in accordance with the above instructions. The
device will not operate with just one battery.
• Set the power source switch (26) to <BATTERY><I>.
• The device is now ready for battery operation.
• To remove the battery, push it in the opposite direction and take it out.
• Switch the lamp off after use.
7.2 Battery charge status control
• Insert 2 batteries into the lamp as described in section 7.1.
• Set the power source switch (26) to <I><BATTERY>.
• Press the button on the battery charging indicator button<BATTERY> (20).
• On the device display, the battery charge status will be shown in values of LO (Low), 25%,
50%, 75% or 99%.
NOTE
If the device is operated by the mains power (switch position <II>), the display will always show a
full battery status 99%. The battery status check will only work correctly if the mains power cable is
removed.
NOTE
Note that all Walimex pro Niova 600 / 900 Plus series devices must generally be equipped with two
sufficiently charged batteries. The device will not operate with just one battery.
