This high-power 51 × 30 cm aluminium illuminator is equipped with highly efficient high-CRI SMD (surface-mounted) LEDs and replaceable optics.
Its optical system consists of 8 sets of TIR (total internal reflection) lenses that affect the two basic photometric parameters of the device: light beam angle and maximum attainable lighting intensity.
Our production program covers monochromatic lights S8d and S8t (respectively daylight and tungsten), and a bi-colour model S8bi with stepless 3200 K–5600 K colour temperature adjustment capability, as well as vertical versions of all these models, designated S8V.
State-of-the-art high-CRI multiluminophore LEDs and a modern microprocessor-based controller allow the device to emit a high-quality luminous flux of up to 10,000 lm that is completely free from the flickering effect. Replaceability of optics enables to modify the light’s photometric properties within a wide range.
S8 allows to adjust light output practically without affecting colour temperature. It is a tool perfect for use both in outdoor filming locations and in the studio. The optional DMX512 controller enables to control the light remotely in television studios or when the light is hard to reach.
S8 is equipped with 8 sets of TIR lenses as standard. Replaceability of lenses allows the user to adapt the parameters of a particular device to his or her current needs. Thus it is possible to illuminate wide frames from a small distance as well as to achieve very high lighting intensity with low power consumption.
There are three types of lenses available, differing in terms of angle: 30, 60 and 90 degrees. With lenses removed, the light emits a 120-degree light beam. The table below shows the photometric properties of individual S8 models configured with different optics.
In the back of S8 there is a control panel consisting of buttons for device operation, a display for indicating current per cent brightness setting and current colour temperature expressed in kelvins (only in S4bi), diodes signalling the operation mode, battery seats (optional) and mains power supply socket. Controllers of S4bi lights have a non-volatile memory for three panel presets that include brightness and colour temperature settings. Calling the presets from individual memory units is done by pressing the related memory buttons; storing a preset requires holding the chosen button pressed for a while. Indicators found next to the buttons signal the use of memory.
The unique functionality of Akurat S8bi comes from the multitude of battery supply options. The light can be adapted for small, common and inexpensive 7.4 V camera batteries offered by various manufacturers. The light requires two batteries of that type, and such a supply allows S8bi to operate at full power for up to 90 minutes. There are also adapters available for powering S8t and S8d from 14.4 V batteries with a V-Mount or a Gold Mount bracket. Adapters of that type can be installed in S8bi too. The controller of the device is equipped with a battery state tester. Current battery voltage is indicated with an accuracy of 0.1 V. The device signals low battery by flashing indicators.
S8 is equipped with a fixing yoke made from aluminium profiles. The yoke enables to orientate the light in two axes. The light can be fixed in the vertical axis with convenient adjustable levers, while fixing to a tripod or in the horizontal axis is done by means of a standard female 5/8” adapter. One accessory useful for tripod mounting is an adjustable head that enables to position the yoke at any angle. It is also possible to equip the head with a diffuser umbrella.
