da cannon femto + DFA7

And here the variant for velomobiles with a lower hood. The sail effect of the wing profile is still waiting for the wind tunnel measurement ;-)

 

Light cannon in super mini format, front white, rear red with very bright LEDs. Water resistant. Suitable as position light for velomobile. In terms of brightness, it can replace the normal (bicycle) rear light, but has no STVO or other approval. The brightness at the front and rear is optimal for operation at night, i.e. clearly visible, but not excessively dazzling.

 

This version has been specially developed for the DF , DFXL and Alpha 7 velomobile types. With a 50mm long wing and an 8 ° incline of the foot, it fits perfectly behind the hood and still shines over it.

 

Power supply (on-board battery, etc.) not included.

Housing: polyamide

New: Housing made additive "+", two M4 threaded rods for fastening (twist-proof), no separate circuit board, knurled nuts for easier assembly, longer connection cable (2.5m)

 

Data

Length: 70mm

Diameter: 7mm

Diameter of the light emmiting surface: 5mm

Lower edge of the light emmitting surface: 50mm above the body

Connection thread: 2x M4x10mm, 17.5mm center-to-center distance, knurled nuts included

Connection cable: 2.5m

Weight including connection cable: 20g

Input voltage range: 6… 24VDC, reverse polarity protected

Overvoltage protection: no, max. 24V

Undervoltage safe: yes, but then also lights up darker, below 5.5V no longer at all

Power requirement: approx. 95mA at 7.4V, decreases with higher input voltage

Power requirement: approx. 0.7W

The brightness is always the same within the input voltage range.

 

White LED:

Luminous flux (calculated): 21lm

Beam angle: 80 °

Luminous intensity: 14cd

Color: cool white

 

Red LED:

Luminous flux (calculated): 26lm

Beam angle: 80 °

Luminous intensity: 18cd

Dominant wavelength: n / a

 

The angle of radiation means the viewing angle with the greatest brightness. The lamp is still visible from all directions, i.e. 360 °.

 

The LEDs are not pulsed and are therefore absolutely flicker-free.
