Lights & floodlights FAQs

The scope of delivery of the first generation of work lamps in the brennenstuhl® Multi Battery 18V System (Art. No. 1173140600 and 1173140400) did not include the adapters for compatibility with the 18V batteries of the manufacturers Festool and Flex, which have been available since 08/2022?

Please contact our service department via the contact form. You will receive the required adapter on presentation of proof of purchase.

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.

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.

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”.

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.

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.

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.

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).

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).

Yes, for most brennenstuhl halogen floodlights you can order replacement glasses via our sales department.

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.

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.

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.

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.

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.

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.

The decisive value for the brightness of an LED illuminant is the luminous flux. This describes the actual light output of the light source and is expressed in the unit lumen. Luminous flux indicates how much light or brightness a light source provides in all directions. This efficiency describes the ratio of the emitted luminous flux in lumens and the supplied energy in watts. However, this only provides information about the power that is emitted by the lamp of the spotlight, for example, but not how much finally reaches a certain surface such as a screen or a delimited wall.

ANSI (American National Standards Institute) -Lumen indicates the brightness produced by a lamp and is determined by means of a standardized measuring method. The ANSI lumen is a colloquial term used in connection with projectors and beamers and plays a major role here, as it describes how brightly a video projector, for example, projects its images onto the wall. The higher the number, at the same distance from the surface, the brighter the image appears.

In addition to the brennenstuhl® professionalLINE battery AB 1805 (art. no. 9834518), you can also use all batteries from the GBA 18 V x,x Ah Professional series. Due to the limited space available due to the battery cover with the battery-powered and hybrid floodlights LA 4000 / LA 4010, only batteries up to max. 6.0 Ah can be used with these floodlights!

The use of the Bosch 18V ProCore series 4, 8 and 12 Ah is not possible with this spotlight series due to larger dimensions.

If the battery is almost flat, the LED floodlight will flash several times. Afterwards, the floodlight remains to light up with reduced brightness before it is switched off by the deep discharge protection function. This ensures sufficient time to change the battery or complete work.

When you work on construction sites, sudden power failures are not uncommon. In the worst case, you will then stand on a ladder or scaffolds - in the dark. In order to avoid dangerous situations with possible injuries in this case, our hybrid floodlight has a special emergency light function. In the event of a power failure, the spotlight switches automatically from mains to battery operation. This ensures that further orientation is still possible and the work can be completed, if applicable.

The professionalLINE hybrid floodlight does not have a charging function. So for charging, the battery must be removed and either be charged using the brennenstuhl® professionalLINE charging unit CB 1801 (art. no. 9831860) or a suitable Bosch charging device (e.g. AL 1820 CV Professional or AL 1860 CV Professional).

The DARGO hybrid floodlight, on the other hand, charges the battery when it is connected to the mains via cable.

Brennenstuhl® offers spare parts for many products from the professionalLINE range.

No, because the protective cover can only be used up to and including Bosch ProCORE 18V 8Ah.
