FAQ - Lamps and Lights

The infrared motion detector reacts only for a very short distance. Why is this?

The infrared motion detector (also called PIR motion detector) reacts to marginal changes in the surrounding temperature, for example, through the movement of people in the detection zone. At very high temperatures, such as in summer, the range is reduced, since the difference between the ambient temperature and the temperature of human bodies is only very slight. This makes identifying movement more difficult for the motion detector. The specified maximum range for optimum conditions is a temperature of 20°C and no wind. Other factors such as installation height or the direction of the motion detector can play a role as well. Infrared motion detectors always detect movement lateral to the device better than movement towards the product. For optimal function, please note all installation instructions in the manual.

Which lights do the tripod BS 250 and Brobusta ST 300 fit?

In general, our lights with mounting brackets can be used on these tripods. Always make sure that the light fixture is positioned correctly and the tripod may only be so far extended that in the event of an inclination of the standing surface by 15 degrees, the tripod, including the assembled light fixture, remains firmly standing, even when it is touched. For the Power Jet-Light 4x36W with steel brackets (1172660) we recommend the Tripod BS 250 (Note: Do not use the Power Jet-Light lights in the stand if the mounting bracket on the tripod is missing!) If you want to mount two 500W halogen lights (H 500) on a tripod, please use the tripod Brobusta ST 300.

Are there replacement glasses for BAT® halogen lights?

Yes, you can order replacement glasses for most BAT® lights through our sales force.

Can existing conventional halogen rods also be inserted, if needed, in a halogen light intended for energy-saving halogen rods?

Yes, the energy-saving halogen rods are constructed identically to the conventional rods, and if needed the existing conventional halogen rods can be inserted in the new halogen lamp. The same is true for the insertion of energy-saving halogen rods in old halogen lamps. The lamp must have the correct socket (R7s) and the right size (approx. 78mm by H150, approx. 118mm by H500).

Why can't you touch a halogen rod with bare hands?

When fingers touch glass, they leave behind small fat residues, which can lead to surface tension, which in turn can lead to a bursting of the glass when subjected to the intense heat of usage.

Why are the rods so sensitive for mobile halogen radiators?

Standard rods have a coil that is only very lightly supported by a support ring in the glass framework. This coil becomes glowing hot during use and can rock back and forth within the glass if the lamp is moved. This coil could potentially swing so strongly that it touches the glass and destroys itself. Hence when using these affordable halogen rods it is important to move the lamp only when it is turned off. We offer higher grade rods with a more robust coil and built-in fuses for mobile use. These have the following article no : 300 Watt Art. Nr. 1 17012 0; 500W Art. Nr. 1 17009 0.

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-Eco-design directive, since September 2009 our halogen lamps now use energy-saving bulbs. These energy-saving halogen rods require 20-30% less energy for the same illuminating power, e.g. only 350-400W instead of the previous 500W. There are further advantages: the low power requirement reduces energy consumption, which reduces your electricity bill. In addition, this measure helps spare our energy reserves and preserves our environment.On the box of the halogen spot lights with energy-efficient halogen rods you will see the EU flag as well as the information equivalent to 500W “or “equivalent 150W ” imprinted.

How can the light bulb be changed on a pocket torch?

For pocket torches 1 17713 0; 1 17710 0; 1 17706 0, the illuminant cannot be swapped out. For all of our other lights, instructions for changing the illuminants is included on the face plate.
