Specification

Available in:
  • Lumotec IQ-X 150 Lux
Description
    The classically designed aluminium bodied IQ-X E is now available in the E-Bike version. Offering 150 Lux output this light can be used with E-Bike systems with 6 - 60 V DC power supply. It incorporates B&Ms IQ2 technology and offers an extensive comprehensive light field together with Light at close range. This means that you get a very impressive light affect. It offers a very homogenous light field which spreads out in front of the bicycle, enabling the cyclist to accurately see everything - the immediate close range, the width of the road exceeding the kerbside and also more than 40 metres distance. Cycling in the dark becomes a pure joy and is safer than ever. The light also has B&Ms integrated daytime running light system which enables other road users to see you via the use of separately incorporated LEDs.

    For use with E-Bikes only

Specifications
    Please note the following recommendations from Busch & Muller if you are planning to install your own E-Bike lighting system:

  • Establish and/or measure the voltage on the cables or connecting point intended for the connection. Make sure this is within the parameters of the light specification
  • Establish and/or measure the polarity of the above mentioned connection and make sure to connect respectively to the correct pole using the instructions and/or the + / - signs on the light
  • If you are not able to establish either of the above, or are not sure then please refer to your local electric bike specialist to install the lights for you

  • Stainless steel mounting double jointed bracket with secure cable guide
How To Recognise A Good Head Light
    Illumination levels of headlights can be measured using different units - e.g. Lux or Lumen. B&M states the light output of headlights using the unit Lux. A Lux value provides the illumination level in relation to its distance from the light source. It is exactly this relation which is a deciding factor when considering a headlight, because it states the amount of light on the road. The value Lumen in turn states how much light exits the headlight at the light source, no matter if the light shines onto the road or is lost as stray light. That is why this value as excellent as it might sound can be very misleading

    However even the Lux value provides only partial information about the out put of a headlight. Also important is the quality of the light field which is created on the road. Its width and depth; its light quality that is both homogenous as well as comfortable to look at with the human eye and its Lux values does not say it all. And finally its glare free light/dark boundary are all qualities that cannot be stated using just measured data. What is important is how and what the rider can see for safer more comfortable riding

    It is notable that some manufacturers cite "visibility from x metres" as a means of evaluating headlamp quality, a rather meaningless value. There is no objective measuring method and the safety gain is only an individually perceived factor because it implies ideal conditions (i.e. no interfering light, "clean" air, unhindered visibility, universally identical abilities of human eyesight ...) that in reality do not exist. That is why B&M forgoes quoting a value that they consider useless and that only feigns objectivity. The most relevant question is this: Is there any real value in being seen from a distance of 1000 metres?
B&M Day Light Running Mode
    Daytime Running Light. Better Seeing And Being Seen

    For bicycles which are less conspicuous in traffic by nature a daytime running light is a substantial advantage. LICHT24, the daytime running light from B&M is the ideal solution. Additional signalling LEDs shine upwards and generate maximum visibility. The "regular" riding light is focused on the road and limited by its clearly defined light/ dark boundary to prevent glaring oncoming traffic.

    When a headlight with LICHT24 is switched on it will always shine: during day and night. LICHT24 has a day mode and a night mode. As soon as the integrated sensor is activated, it switches automatically between both modes. LICHT24 is approved by the German road traffic regulations. The day mode may also be used at night because the main LED is always active
Light At Close Range
    For a secure ride it is important to be able to see the road directly in front of the bicycle. Bumps or potholes in the road can be seen better if this area is lit and can be circumnavigated by short and intuitive steering. During darkness this is only possible if the area between one and four metres in front of the bicycle is lit brightly and homogenously. Subjectively the need for light at close range is higher the slower one is riding, because one's balance can more easily be influenced by obstacles. "With light at close range" means that the light field emitted by the B&M headlights starts directly one metre in front of the bicycle
IQ Technology
    IQ Technology: The Light Revolution

    The core of IQ-TEC is the revolutionary idea not to use a high output LED as an indirect light source. The complete reflective surface is used to focus and guide the light. If one looks into the reflector of an IQ headlight one only sees the metalised surface. Once the headlight is turned on what takes its place is "nothing but light". Since 2007, B7Ms innovation has continually been developed further.

    Conventional technology: A light source sits in the centre of the reflector. The result: stray light and loss of efficiency.

    B&M have developed state of the art technology called "IQ2 TEC" and "IQ-TEC PREMIUM". In comparison with the first IQ generations, the new IQ-TEC versions offer double the light output and an almost twice as wide, very extensive field of light. Everybody who has cycled with an IQ TEC headlight at night will never again want to do without this light experience
