Successful niche product

I have one of these lamps tasted in a flashlight, where they naturally much brighter and whiter than the original light bulb shines, but mainly I wanted one for a e-bike headlights. Although often the view to know that light bulbs in bike lights can not be so easily replaced by LEDs, the reflector characteristics would not fit etc, but I did not longer driving around with the included museum mature technology and have a try daring.

Behold, assuming an appropriate supply voltage within the specified range (I have a small DC-DC converter for front and rear lights installed, which is connected to the driving power battery is; no Dynamo present and also in DE now fortunately no longer mandatory), this lamp can keep up (1 watt) loosely with the previous 5-watt light bulb and holds at least theoretically, also much longer. A bicycle headlights also not hidden and illuminates all the more of the road, if it is well adjusted.

For driving on unlit paths / roads with more than 20 km / h or so, the power is but rather to be weak (a version with 2 or 3 watts would be desirable), at least they are not registered in DE can me in AT anyway not matter. So far, probably not a bad choice compared to the more expensive and less attractive special e-bike headlights.
