D4 – soft bi-colour LED panel for reporters and for studio
We present a new series of Akurat Lighting D-Soft LED panels with permanently installed high efficient diffusing optical system.
The use of innovative diffusion materials allowed to obtain unbeatable photometric parameters. High performance is a significant energy saving, especially important with battery working. Perfect diffused light gives a lovely soft shadows, without a matrix structure.
D4 is the smallest model of D-SOFT series. This 30 × 27 cm aluminum illuminator is equipped with two sets of highly efficienthigh-CRI SMD LEDs. Such a design, combined with a microprocessor-based controller, provides brightness and colourtemperature adjustment capabilities, three memory banks for user settings, battery state readout function and low-battery state indication.
We offer the D4 panels in a number of different battery options.
Basic technical data:
Luminous flux of up to 4500 lumens
Maximum electric power: 50W
Supply voltage: 13-18V

Excellent photometric performance D-SOFT owes to the use of advanced materials for the construction of the optical system. It consists of a diffusion film of a high permeability and the structure of micro-lenses placed in front of LEDs, whereas the low-lossy reflector of a high diffusion is located behind the diodes. Proper combination of these materials guarantee beautiful soft light with a high intensity.
D4 panels are offered as the studio kit with AC power only, or as the reporter kit with AC and battery power and carrying bag.
Control panel and user memory in D4
In the back of D4 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, diodes signalling the operation mode,battery seats (optional) and mains power supply socket. Controllers of D4 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 optionalDMX512 controller enables to control the light remotely in television studios or when the light is hard to reach.
The unique functionality of Akurat D4 comes from the multitude of battery supply options. The light can be powered using small, common and inexpensive7.2 V camera batteries offered by various manufacturers. The device requires two batteries of that type, and such a supply allows it to operate at full power for up to 90 minutes. There are also adapters available for powering the light from 14.4 V batteries with a V-Mount bracket. 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.
