This is the product photo I downloaded in 2011:

You can see the lens before the bulb is now missing a section compared to the older Spanninga 15. This was what I noticed already then, but only in 2013 was I interested enough to follow up on this and see if there was a real change.

When I looked at the lamp, lit, in daylight, the light seemed not red enough, it seemed a diluted red, as if it's not filtering out enough of the other colours coming from the bulb. This makes the light colour almost crimson (some white mixed with the red). I think this must have been done to achieve more light output by bending the rules...

More to come.

Medium distance test 1 of taillamps (2013-2-21). It was again evident how diluted the red is. Not good! Visibility is comparable to the old version in this test.

Beam shots

See the camera settings page for more on the setup and settings to make pictures of the beams of taillamps.

The corner & wallshots have been made with a 0.6W bulb.

Out of a corner (showing how much light is cast upwards, forwards and to the sides) [ F3.9 & F1.8 ]:

Note how little light this taillamp gives, and almost nothing upward/forward as the current StVZO requires.

Wallshot (showing the beam pattern):

Visibility from various angles (0°, 45°, 90°, 135°) [ 0.5m, zoom x3, F3.5, ISO80, 1/250s & 1/60s ]:

The red light isn't really red but a diluted red. Could this be confused with a yellow headlamp under unfavourable weather circumstances? I don't know without doing further tests, but I don't like it. So already for this reason I don't recommend this lamp.
