![]() The beam distance indicated in the table is the maximum distance that is illuminated at 0.25 lux or full moonlight. Taking the 3 specifications directly from the FL1 table helps to make an informed decision on what type of flashlight is ideal for your intended application. For this particular article we’re more interested in lumens (light output) and Candela (Peak Beam Intensity) or brightness, plus the beam distance. ![]() The FL1 Standard helps to provide a better understanding of all the technical details of a particular flashlight and how they have a direct impact on performance in specific practical applications. You will see an FL1 table with it’s various icons on most quality flashlight manufacturers packaging. In 2009 the FL1 Standard was introduced as a standard at which flashlights are now rated. The FL1 Standard helps with this understanding. ![]() In summary, using both lumens and candela units of measurement together helps pinpoint what type of application a flashlight is most suited. Whether it’s main purpose is for tactical, hiking, search and rescue or as general outdoor / indoor flashlight. It is the brightness of a flashlight beam or Candela that must also be considered when deciding what purpose a flashlight is good for. The optics and reflector used at the front end of a flashlight also have a direct affect on how the lumen output is distributed. Optics used at the front end of the flashlight.Ĭandela rating determines the brightness of the beam at its most intense point.Candela (cd) rating – Measure of brightness / luminous intensity centre of the beam.The reasons why these 2 flashlights with identical lumens have varying brightness is down to a number of factors: ![]() If you were to choose 2 different flashlights, each with 1000 lumen output, you may find that both have different brightnesses at various distances. You can find more information on the products here.Lumens are the measurement of the total flashlight output, they are not a measurement of the brightness. The Panel 1200 Direct/Indirect luminaires marketed for lighting professionals via wholesalers are available under the LEDVANCE brand. Additionally, the suspension steel-wires allow to position the luminaire on the required height. The transparent electrical cables can be easily wired thanks to fast-connectors. The luminaire is very slim and features sleek high-quality styling with an aluminum frame and rounded edges. The Panel Direct/Indirect series follows the modern SCALE design language by LEDVANCE, winner of the German Design Award 2019 in the Light category. Minimalist, functional design and easy installation LEDVANCE grants a guarantee of five years for all luminaires of the new Panel series. The Panel 1200 Direct/Indirect luminaires are also available with DALI electronic control gear as an option. Further, the included driver is integrated in the canopy, what leads to more flexibility in case a change is necessary. The luminaires of the new series cause low maintenance and operational costs due to a good luminous efficacy of up to 110 lumen per watt and a lifespan of up to 80,000 hours (L70/B50). Thus, a Unified Glare Rating less than 19 (UGR<19) in accordance with the norm UNI-EN 12464-1 can be achieved. Thanks to the micro-prismatic high transmission PMMA light guide, a homogenous and controlled light distribution is provided. The new Panel 1200 Direct/Indirect luminaires deliver 70 percent direct light for the workplace and 30 percent indirect light for basic illumination with a luminous flux up to 4,000 lumens (2,800 lumens down / 1,200 lumens up). High quality of light – low maintenance and operational costs With the new Panel Direct/Indirect, LEDVANCE launches a luminaire series that meets these specific requirements. Only suitable lighting solutions that are ergonomically well-designed can create a productive working environment, help to enhance the employees’ concentration and thus offer benefits for companies in every sector. Key demands include widely glare-free light for screen-based work, uniform distribution of light and adequate illuminance. Lighting systems for office buildings have to comply with numerous standards, directives, laws and guidelines and have to take into account different health and safety requirements as well as scenarios depending on the architecture, usage and area size.
