![]() ![]() This will ensure a stable high light output for a much longer period, and prolong the lifetime of the LED Chip. That is why all of our flashlights and headlamps are equipped with a solid metal heat sink, which uses the entire device to efficiently divert the heat throughout the core structure. It is important to keep in mind that the more power consumed the more heat is produced, and heat will always result in a loss of energy. The LED Chip is more efficient and will convert much more energy to light than the halogen bulb. It is also worth to know that 1Watt halogen and 1 Watt LED do not produce the same amount of light. It will only tell you how quickly it will drain the battery, and not how much light it produces. That is why you should not look for the amount of watt consumed, when buying any kind of light. watts, easy to ready lumens chart, new light bulb laws and more at Lumens. The short answer is no, Watt shows how much energy the product consumes, not how much light output (lumens) it provides. Learn the definition of lumens, the difference between lumens vs. In order to get a constant light output, we use a Constant Current Output technology in some of our products in order to get the highest possible light output for the entire life of the battery.Ĭan I use Watt to determine the power of a flashlight Watt is a unit for power consumption To prevent this in our products, we perform light tests on all of our products to ensure that the lumens value is correct. Most flashlights and headlamps quickly drop in lumens and promise a higher lumens output than they can achieve. We have one at our factory and one at our head office to ensure that each batch is perfect and delivers what we promise. When we measure the amount of lumens, we use a highly specialized light sphere from Everfine. ![]() Producing and creating a perfect beam pattern does not reveal enough information to show how the light output is created. But lumens will only show us a part of the picture. When we test and compare our products, we use lumens to see the total amount of light output. You can roughly say that the more Lumens the brighter the light. LM (Lumens) is a measurement unit, which tells what the total amount of light emitted from a flashlight or headlamp. It describes on the one hand a light source’s impression of brightness, and on the other, a surface and therefore depends to a large extent on the degree of reflection (color and surface).Lumens and light Luminous flux is know as Lumens and is a unit of light Luminance is the only basic lighting parameter that is perceived by the eye. Performance of very special visual tasks of extremely low contrast and small sizeĪ l = area per lamp (m 2) Example - Illuminationġ0 incandescent lamps of 500 W (10600 lumens per lamp) are used in an area of 50 m 2. Performance of very prolonged and exacting visual tasks Performance of visual tasks of low contrast and very small size for prolonged periods of time Normal drawing work, detailed mechanical workshops, operation theatersĭetailed drawing work, very detailed mechanical works, electronic workshops, testing and adjustments Supermarkets, mechanical workshops, office landscapes Normal office work, PC work, study library, groceries, show rooms, laboratories, check-out areas, kitchens, auditoriums Warehouses, homes, theaters, archives, loading baysĬoffee break room, technical facilities, ball-mill areas, pulp plants, waiting rooms, Working areas where visual tasks are only occasionally performed Recommended light levels for different types of work spaces are indicated below:Īreas with traffic and corridors - stairways, escalators and travelators - lifts - storage spaces For precision and detailed works the light level may even approach 1500 - 2000 lux. Today the light level is more common in the range 500 - 1000 lux - depending on activity. Earlier it was common with light levels in the range 100 - 300 lux for normal activities. Additional lighting is often necessary to compensate low levels.Īccording EN 12464 Light and lighting - Lighting of workplaces -Indoor work places, the minimum illuminance is 50 lx for walls and 30 lx for ceilings. In the middle area it may be as low as 25 - 50 lux. In a building in the area closest to the windows the light level may be reduced to approximately 1000 lux. ![]() The outdoor light level is approximately 10000 lux on a clear day. ![]()
