LED projectors are becoming increasingly popular. It must be admitted that they provide a good luminous flux maintenance factor, as well as luminous efficiency. A properly selected LED floodlight provides maximum durability, and its service life is long. It is worth learning more about this topic.

What level should the luminous flux maintenance factor be?
The luminous flux maintenance factor is nothing more than the quality of the fixture or light source. It indicates the power loss that can be expected when it reaches 85% of its service life. Luminous efficiency indicates how many lumens from one Watt a light source can achieve. The factor significantly affects the quality and durability of the diode. It also ensures safety of use. The longer the durability of a given light source, the longer it will last.
If the luminous flux decrease is greater than declared by the manufacturer, it means that the given light source is already damaged. The percentage of light sources that may be damaged before reaching the L time should be classified as damaged. The damage factor itself can be defined by the symbol Fy. It can range from 10 to even 50%. Of course, the lower this value, the better. If the luminous flux maintenance factor is high, then a constant quality of lighting is obtained. It remains at a constant level. Efficiency increases. This is especially important in places where a large amount of light is required, e.g. in warehouses.
What lumen level should an LED projector have?
A good LED projector should have a certain amount of lumens. At the same time, it should provide energy savings. Of course, the housing is also important, which should be resistant to changing weather conditions. Too much electricity consumption means that your bills will increase significantly, so the LED floodlight cannot emit too high a level of lumens. Basically, the higher the power, the more brightness the LED floodlights emit.
A beam intensity of 1500 lumens means that the device has a power of 30 W. If you want to choose an LED projector that will illuminate a dark space, then of course the number of lumens should be higher. 3000 lumens is considered quite bright, so such a floodlight has a wide range of applications. You can use it at home during renovation work, but also in the office or outdoors. An LED floodlight with a power of 2000-2500 lumens will work well for the workshop.
It can be assumed here that 3 W of power is needed for 1 m2. Of course, you should pay attention not only to the light output, but also to the color of the light. The neutral color of the LED diode is the least tiring for the eyes, so it also has a wide range of applications. If you want to illuminate a work station, it is best to use an LED floodlight that emits light at a level of 1500 lumens. The situation is still different when you want to illuminate the yard.
In this case, a neutral or light color will work well, with the light intensity being around 2000 lumens. To save money, it is worth choosing an LED floodlight with a motion sensor, which is resistant to mechanical damage. At the same time, it has a high color rendering index. If you want to illuminate the garage, you can choose a floodlight emitting a cold light color with an intensity of 1500 lumens.
How much power should an LED projector have on a building facade?
Despite street lighting, you can't always count on good lighting, even on the way home. In such a case, it's worth investing in an LED projector that can be placed on the building's facade. Contrary to appearances, it uses a small amount of energy, especially when equipped with a twilight sensor or motion sensor. The luminous flux of LED floodlights should emit light with a warm color.
At the same time, the power should be selected according to your needs. As a standard, an intensity of 1000 lumens is enough. Thanks to this, such a lamp has even lower power consumption, but the lighting is really very practical and functional. If you want to illuminate a larger space, then of course the power should be higher. In this case, 30 W will work well. Do not forget that such floodlights also have a decorative function.

Is it better to choose an LED floodlight with or without a motion sensor?
The application of LED floodlights is very wide. They can be used to illuminate the road, work station, but also the facade of a building. If you place the LED floodlight outside, remember that it must be resistant to moisture and water. The tightness class should be IP 65.
This means that such lamps are resistant to water jets of 12.5 l/minute from any direction. They are also resistant to dust. The light beam can have a cold colour. These types of floodlights emit a large amount of light, which means that the power consumption is really high. They work best in large areas, e.g. in production halls. The warm colour, apart from providing good lighting, also has a decorative function, so it is best for illuminating facades.
The neutral light beam is the closest to natural light, so it will work well in both outdoor and indoor lighting. If you want to keep energy consumption low, choose products with a motion sensor. Using a sensor means that the lighting only turns on when it senses movement. The light turns on almost automatically and illuminates the area.
Using floodlights with a motion sensor also provides greater safety. It is important to know that because it senses movement, the risk of potential theft of property is much lower. Floodlights are also used in public places. In such a case, you should opt for larger dimensions. Models that have greater power are also needed, and therefore also consume more energy.
What is a flicker indicator and how much should an LED projector have?
The flicker index is nothing more than a feeling of instability caused by a light stimulus. It can occur as a result of voltage fluctuations. It is important to know that too high a flicker index worsens the comfort of using a given lamp. It also causes you to feel great instability. The lower the value, the better, of course. For example, you can choose a halogen LED, which has a flicker index of 0.1%.
It should not be forgotten that too high a flicker index increases the risk of damaging the floodlight. In the case of lamps located in halls or warehouses, for example, the flicker value should be close to 0, while in the case of a building façade, the floodlight may have a slightly higher flicker index, because it does not cause as much discomfort.
LED projectors at the Onninen wholesaler
If you are looking for suitable LED projectors to illuminate your property, the products available at the Onninen wholesaler may be the right choice.
It is worth choosing the LED projector V-TAC Solarny 12W Black IP65, Remote Control, Timer VT-25W 4000K 550lm 8573. This is an extremely economical and ergonomic device. It has a good beam angle of 120 degrees, which means that it will illuminate the area from every side. The neutral color of the light ensures low energy consumption. The set also includes a remote control, which further improves the comfort of use. What distinguishes this device is the fact that the charging time with sunlight is only 4 hours. You also need to know that the ignition time is basically immediate, so it is a really great choice for demanding users.
A good choice will also be the Modus RH100N 74W 4000K 9600lm CRI80 IP65 RH100N4/ND LED projector . It is practical and durable. The special lens optics used provide even higher quality light. This is a model that is waterproof and dustproof. It has an IP 65 protection class.
Another LED projector worthy of attention is the Opal 10W 4000K CCY202 .
