Часто задаваемые вопросы
How do you dispose of accumulators and batteries properly?
Accumulators and batteries that have reached the end of their useful life must not be disposed of with the household waste under no circumstances. This is also indicated by the symbol of the crossed-out wheeled bin on the batteries and/or the packaging.
Used batteries can, for example, be returned to trading companies free of charge. You can find the collection boxes for the take-back of used device batteries e.g. in every supermarket, discounter, drug store or construction market where you can buy new device batteries. In some cases, the municipalities also accept used batteries via mobile pollutant collection points or at recycling centres.
How can the light source of a tube lamp be exchanged?
For lamps, it is explained on the cover how the light source can be exchanged. If the cover does not comprise an explanation, the light source cannot be exchanged.
Why do the bulbs for the halogen spot lights now have lower power (e.g. 350W or 400W) than earlier models (500W)?
Due to the new EU Ecodesign Directive, we have used new, energy-saving lamps in our halogen floodlights since September 2009. For the same lighting power, these energy-saving halogen tubes need 20-30% less energy, i.e. only 350-400W instead of previously 500W. This offers several advantages: The reduced power that is required on the one hand reduces the power consumption, which again reduces your electricity bill. On the other hand, this measure supports the economical handling of our energy reserves and the environmental protection. On the cardboard box of halogen floodlights with energy-saving halogen tubes, you can see the EU flag as well as the note “corresponds to 500W” or “corresponds to 150W”.
How do you dispose of LED products properly?
Used LED lamps or LED lights must not be disposed of with the household waste as they contain electronic components. Dispose of these products with the public disposal centres. The latter include recycling centres available in many cities, however also the so-called mobile pollutant collection points.
The environmentally friendly disposal ensures that precious parts of the lamps are not lost but recycled. In the recycling of used lamps, it is also possible to professionally remove the low quantities of pollutants that are contained.
What does colour temperature mean? What does the Kelvin value indicate?
The colour temperature is a dimension to specify the relevant colour impression of a light source. The colour temperature unit is Kelvin (K). You can divide the colour temperatures into different light colours, namely warm white below 3300 K, neutral white 3300-5000 K, daylight white above 5000. Depending on the application, different colour temperatures and/or light colours are recommended. For the living area, warm white light lends itself while you mostly use light of the daylight white range for working light.
What does the lumen indication mean? How bright are the LED lamps as compared to a traditional light bulb?
Lumen (abbreviation: lm) is the unit of luminous flux and indicates the brightness of a light; the higher the lumen value, the brighter the light.
To compare the brightness of a LED light with a traditional light bulb, you can use the following scale. For instance, if you would like to compare a LED floodlight with 2,500 lumen (lm) with the brightness of a light bulb, look for the relative lumen indication or the nearest value on the scale, in this case e.g. 2,452 lm. Above on the scale you can now find the Watt indication of an approximately comparable light bulb, in this case 150W. You can therefore roughly compare the brightness of the LED floodlight with 2,500 lm to a 150W light bulb.
Can the LEDs be exchanged?
In almost all LED lamps, the LEDs are fixedly installed and cannot be exchanged by the user. It is easier and thus cheaper to produce lamps with fixedly installed lights than those with exchangeable lamps. If LEDs are used, an exchange during the usual operating life of the lamp is normally not necessary as with typically approx. 50,000 h, the useful life of the LEDs is many times that of traditional lamps (light bulb only approx. 1,000 h, halogen light only approx. 2,000 h).
Is it also possible to use traditional halogen tubes that might still be available in a halogen floodlight with energy-saving halogen tube?
Yes, as the energy-saving halogen tubes are structurally identical with the traditional halogen tubes, you can also use traditional halogen tubes that might still be available for the new halogen floodlights. The same is true for the use of energy-saving halogen tubes in older halogen floodlights. You have to watch out for the correct fitting (R7s) as well as the size (approx. 78 mm with H150, approx. 118 mm with H500).
Are there replacement glasses for brennenstuhl halogen lights?
Yes, for most brennenstuhl halogen floodlights you can order replacement glasses via our sales department.
For which lamps are the BS 250 and Brobusta ST 300 tripods suitable?
Generally speaking, our lamps with mounting bracket can be used on these tripods. It must, however, always be noted that the lamp has to be positioned and the tripod may only be extended to an extent that with an incline of the standing area of 15°, the tripod including the mounted lamp must still stand securely and must not fall over - even in case of contact. Please also note the maximum bearing capacity of our tripods (10kg for ST 300, art no. 1170310 and 7kg for BS 250, art. no. 1170610). For this reason, the chip LED floodlights with 100W or more power are not suitable for use on one of our tripods.
The infrared motion sensor only reacts at a very short distance. What may be the reason?
Infrared motion sensors (also referred to as PIR motion sensors) react to changes in the ambient temperature, e.g. due to the movement of a human being in the detection area. With very high ambient temperatures, e.g. in summer, the distance is reduced as the difference between the ambient temperature and the temperature of the human body is only very low. Thus, it is more difficult for the motion sensor to detect a motion. The specified maximum distance is true for perfect conditions at a temperature of 20°C and without wind. Other factors such as the installation height or the orientation of the motion sensor may also play a role. Infrared motion sensors always detect motions transversely to the device better than motions directly towards the product. For perfect functioning of the product, please always observe all installation notes in the instructions.
What will I do if the glass of an energy saving lamp or fluorescent lamp breaks?
If a lamp breaks accidentally, there is no acute health hazard due to the little amount of mercury. It is nevertheless recommended to effectively ventilate the room for some minutes and to leave the room. It is best to wear rubber gloves during the clean-up work! In this way, you protect your hands from sharp glass splinters and from contact with mercury. In addition, the following should apply as basic rule: Do not use a vacuum cleaner to dispose of the lamp residues! For with the vacuum cleaner, the mercury droplets may be distributed even more finely and get into the breathing air. Carefully sweep up the lamp residues with a rigid cardboard on a piece of paper or take them up using an adhesive tape; then clean the place at which the lamp broke using a small wet cloth. Put the lamp residues, cardboard, adhesive tape and cloth into a container that can be closed in an airtight manner, e.g. a screw-cap container, and bring it to the local disposal centre.
What will I do with used energy saving lamps or fluorescent lamps?
Energy saving lamps or fluorescent lamps must not be disposed of with the household waste or waste glass under no circumstances. They still contain small amounts of pollutants (e.g. mercury) that might damage the environment! Dispose of these lamps with the public disposal centres. The latter include recycling centres available in many cities, however also the so-called mobile pollutant collection points.
Why is it not allowed to touch a halogen tube with the hands?
By touching the glass body with the fingers, you leave minor fat residues on the glass body that may lead to surface tension and thus, due to the intense heat during use of the floodlight, to the bursting of the glass body.
Why are the rods of mobile halogen floodlights so sensitive?
Standard rods have a spiral that is only slightly supported by support rings in the glass body. During use, the spiral gets blazing hot and can move back and forth in the glass body when the floodlight is moved. The spiral may swing so strongly that it touches the glass body and is destroyed. If these favourably priced halogen bulbs are used, the floodlight should thus only be used if it is switched off.
