DARA Lighting vs Illuminance Pulsation Meter

DARA Lighting is the easiest way to control your lights and reduce energy bills. The solution is highly flexible, suitable for any type of business – from office spaces, manufacturing, industrial and logistic applications all the way to the largest of retailers. With just a few taps you can control luminaires one by one or as a group. For example you can set up a group for the office space and another one for a meeting room or a kitchenette and dim up or down lights in each of these spaces. You can also create scenarios depending on the day of the week, time of the day or other relevant events. Set the lights at a higher dim level for the office space and a lower dim level for the corridors and save all these settings in a scenario. Or set all lights to dim down once office hours or retail open hours are over. Share your network with other users and let them adjust the lighting. Dara Lighting has several levels of users (network owner, administrator or simple user), each with their own corresponding lights. DARA Lighting has mesh capabilities, thus the functionality is dependable, redundant and resilient over hundreds of square meters. Due to its dual control – both BLE (Bluetooth Low Energy) for DALI communication and Wi-Fi, – a user can individually control a large number of luminaires. With this solution any business has the power to tailor its lighting preferences and, at the same time, greatly reduce its energy expenses by making sure light is present only when needed.

The application will help you choose a lamp, monitor or laptop with a screen without pulsations. A high coefficient of pulsation can affect fatigue, well-being and eye strain. The application allows you to measure the ripple coefficient of radiation sources in the visible spectrum: - LED, halogen, fluorescent lamps and incandescent lamps - various lamps - LCD and LED monitors and TVs The readings are not 100% reliable and the average error depending on the light source and the frequency of pulsation can be more than 10%. In order to take measurements, you need to bring the phone to the measured source and press the start button. The measurement results will be updated in real time, the arrow will show the ripple factor, and the scale will be filled from green to red. For best results, keep your phone straight. If the phone is not fixed, an image of the shaking device will appear in the lower left corner of the screen and the readings will be very different from the actual ones.
