Busch and Muller Lumotec IQ-X - New for 2015

Busch and Muller Lumotec IQ-X - Intro

The advances in LED tech over the last 10 years have been amazing. Light provided per watt of power used is ever increasing, and for those cyclists sticking with dynamo powered lighting, the rewards are great.

Busch and Muller form the back bone of the dynamo power cycle lamp market, and they have announced a new headlamp in August 2015.

I won't lie I am quite excited about it. It is similar in build to the Edelux 2, with an aluminum body and 100 LUX rating. Being the beam is wide this probably translates to around 500 lumen, from a 2.4 watt LED.

Busch and Muller Lumotec IQ-X -How Powerful?

The Cyo headlamp from Busch and Muller has proven very popular, and is generally held as being very reliable. At 100 lux, this new addtion trumps previous 60 and 80 lux versions of the Cyo. It features a super wide beam similar to the Luxos range of lights offered by Bush and Muller.

The below beam pictures taken from the Bush and Muller Website  show comparisons between the old CYo Models and the New Light IQ-X.

60 Lux - I ride with this light at present. It is OK off road, Ample on Road)

80 Lux - I have just purchased this light so will report back soon.

100 Lux - Maintains Light Range and adds to Spread.

It is important to note that the beam of these headlights is well placed on the road. With most off road battery powered headlights, there is a great deal of "splash" from the beam with light shooting out all of the place. This is handy off road as it enable you to spot overhead branches (!) etc.

Busch and Muller Lumotec IQ-X - Is it Worth Buying.

Reading reviews on the web there has been mixed reviews with regards to the casing design of the Luxos Range, most reviews are favorable. The Edelux II has good reviews and is powered at around 90 LUX. With this light I think Busch and Muller are trying to amend there casing design (?) and up the power a little.

If you cycle in the city or other roads with their own lighting, then this light would be serious over kill. By means of comparison a 60 LUX light such as Busch and Muller Lumotec IQ Cyo T  will give adequate light for 30mph road riding on unlit roads. Off road you will have to slow down a bit.

One of the the thing often overlooked if the pattern of the beam. A very powerful light will "project a spot on the moon" but will  give little light for peripheral vision. From the beam shots above I would say this new IQ-X from B&M gives not only a far reaching beam, but a wide one too. Which would in my opinion warrant an upgrade. Of course if you are alreday using a quality 80 or 90 LUX light then the gains will be less.
