BBB Cycling Australia - Light Guide 2020

FEATURES LIGHTS
Regulated lights emit over their entire burn time
a constant amount of light due to an electronic
regulation system. Is the battery (pack) empty, can’t
the same amount of light be emitted anymore, than
the light will automatically turn off. Because you
don’t want to be surprised, these lamps feature
a battery indicator.
Rechargeable by USB design.
Intensive lights also produce a lot of heat. Therefore
BBB high power lights are equipped with ACS
(Airflow Cooling System ). Due to the special design
of the aluminum casing parts of the light the air ow
passing by while cycling is cooling down the light.
This guarantees optimum heat control of the light.
Using an ACS controlled light, without riding will
damage the light.
LIGHT CONCEPTS
If you want choose the most suitable light set for your bicycle use, it’s
important to have correct and comparative product data. Because
there is no international standard for light sets, BBB measures various
values. With these values you can always compare our products. To
fully understand the values mentioned in the table on the next page,
we explain the concepts used in the table: Candela is the unit of
luminous intensity. Candela indicates the amount of light emitted in a
certain direction of the beam. The in the table noted Candela value is
measured at the center of the beam.
Lumen, the value for the total luminous flux, is the total amount of light
(in all directions) emitted by that lamp.
Lux is the amount of light (lumens) on a certain area. Therefore Lux is
the most telling unity. For example, if you have a light source of 1000
lumens, spread over 1 m², this square meter is illuminated with 1000
lux. When the same 1000 lumens are spread over 10 m², the same
source illuminates a square meter with only 100 lux.
However, when comparing Lux values for different light sets, it’s
important to know the distance from the light source. The larger the
distance to the source, the lower the Lux value will be. BBB measures
the Lux value at 1 and 10 meters. The Lux value at 1 meter is equal to
the value for Luminous intensity (Candela).
The light spot diameter indicates how wide the beam of the lamp is at
1 meter distance.
The burn time of the different lamps gives an indication of how many
hours the lamp will burn. For battery lamps the burn time obviously
depends on the quality of the battery. Burn time for BBB lights with
battery pack is measured with fully charged batteries.
