Supernova E3 Triple LED 800 lumens Have decided on the lamp because it according to the description, the "brightest dynamo powered lamp in the world" should be, and I'm on my daily commute often off the beaten track on unlit paths go. It was delivered in a very valent metal. The foam padding provides excellent protection during transport. Lying inside the assembly materials and a very detailed German manual. Thanks to the latter and a little technical skill, the lamp was mounted and connected in 20min on the bike. The lamp itself is of good quality. Material (aluminum), processing and coating (gloss black) are excellent. This can be expected at a purchase price to the 200Euro however. It has at the back of an on / off switch. The front lens is frosted. To use the lamp came to my Kalkhoff e-bike to 25km / h. Power is supplied by a Shimano DH-3N20 hub dynamo to a 28 "front wheel. Now to the essence: light. Thanks to the fact that I got my tail light is not connected (battery operated with sensor) to the supernova, already go from 10km / h every 3 LEDs. The illumination is very good for the driving speed. From 15-20km / h, it is again bright and then the bill reaches about 40m far forward, with a viewing angle of about 30-40 °. And God said, "Let there be light" Well aside, fun. From a 3W hub dynamo can win only 3W of light output in the best case. Nevertheless, it is the brightest I had to date. Unfortunately, the light scattering is very large. Probably the reason why it has not approved. The color temperature of light is somewhere between cold and warm white. Pleasing to my eye. Unfortunately, the parking light is rather poor. It only lights up a LED and also still very weak. Whether one is as yet perceived by other road users, I dare to doubt. Actually you could forego something entirely. Conclusion: apart from the high purchase price and the fact that the lamp has no further settings (daytime running lights, close-range illumination, etc.) I am very pleased with the Supernova E3 Triple. A lamp for bicycle enthusiasts who need a lot of light, but no additional features.
