** Check out the Intelligent Design Cycles blog for tips on how to wire hub dynamo lighting systems ** Spanninga Elips Xds hub dynamo (dynohub) taillamp We at Intelligent Design Cycles have been in the process of developing high quality but affordable hub dynamo driven lights for a number of years. Our mission is to bring high quality hub dynamo driven lighting systems to the market that rival if not surpass the best in the trade, but would nevertheless be affordable enough that parents concerned about child safety would consider putting them on their children’s bicycles. During the course of this exercise , we have personally tested all the best German, Dutch, Finnish and other hub dynamo lamps we have been able to find with the intention of bringing the best aspects from each maker into our products. Two years later … we are still hard at work (the product development process is a bit more difficult than this former international trade economist imagined). But … There is one Dutch company Spanninga that has developed a dynamo tail lamp incorporating advanced LEDs optics technologies popular in high-end automotive lighting today. Instead of taking the humdrum industry standard approach of emitting raw and unadulterated light via high-intensity single point LEDs which can be harsh and distracting to other road users - particularly other cyclists in group night rides - the Elips relies on high-end "light piping" optics technology to produce an even and clearly discernable, if not gentlemanly, "ring of light". Spanninga acquired this technology from the no longer produced but widely acclaimed Ph illips LumiRing . It goes without question that unlike the average battery powered blinkie - i.e. 99% of rear lamps on the market - the Elips boasts a beam pattern that is optically engineered to meet the demanding German StVZO regulation for bicycle rear lamps. (Please note that the Elips is a steady light and does not have a blink setting which would be disallowed under the StVZO regulation.) In tune with its counterpart for bicycle headlamps, the StVZO requirement for tail lamps derives from the data-rich and extensively studied field of automotive safety. Drawing from its subfield relating to passive lighting in tail lamps, the light emitted from the Elips is shaped to form a rectangular pattern in order to minimize the waste of light going in directions (mostly upwards), which would do little to enhance bicyclists’ conspicuity. Specific brightness requirements at multiple points within this rectangle must also be met, which have been developed based on extensive real-world experience relating to optimizing bicyclists’ conspicuity vis-à-vis vehicles approaching from behind. No less important - indeed perhaps even more so - is that fact that the Elips also directs a portion of light diagonally, sideways and forward. Indeed, automobile-bicycle accident collision research underscores how sideways and frontal conspicuity can be more important that rearward conspicuity. In short, the Elips is not just another bicycle tail lamp, but one that has been painstakingly engineered to deliver conspicuity and safety based on extensive research and experience in the field of passive lighting for automotive safety for rearward lighting. We have been familiar with these lamps for over half a decade and have yet to hear about a failure under normal use to date. As an authorized retailer and distributor of Spanninga products, we also provide a 1-year warranty on these lamps. Specifications Compatibility: This lamp is compatible with all standard hub dynamos headlamps that we sell and are aware of, and is an excellent match with the SunUp Eco bicycle light generator. Standlight: The stand light on the Elips is very bright and will remain on for well over 4 minutes after the bicycle has come to a stop thus easily surpassing the German StVZO minimum performance requirement. Switch: This lamp has no on/off switch, but must normally be connected to a dynamo headlamp that may have an on/off switch. Overvoltage protection: In line with most modern dynamo lights we are aware of, the Elips comes with overvoltage protection insulating the LED from excess power at high speeds. Warning I! Do not use the Spanninga Elips or any dynamo tail lamp without a front lamp. The overvoltage protection for standard dynamo tail lamps is engineered to rely on the extra electrical load produced by front dynamo lamps to function safely. Wiring this lamp directly to a standard dynohub will result in speedy failure of the lamp. Warning II! For the Spanninga Elips or any dynamo tail lamp to benefit from the overvoltage protection afforded by a front dynohub lamp, it MUST be wired directly to the REAR LAMP OUTPUT CONNECTIONS of the dynohub front lamp and NOT IN PARALLEL to the front lamp. Wiring a dynohub rear lamp in a manner other than directly to the rear lamp output connections of a dynohub front lamp will void its warranty. Included mounting hardware:  The light comes with complete mounting apparatus for 50mm bolt spacing rear racks including star washers and bolts. Optional mounting hardware: A 2-meter cable with spade connectors (headlamp end) and neatly trimmed cable (tail lamp end) is available for an additional USD 2.00. Reflector: The integrated reflector is StVZO compliant "Z" standard quality meaning that it meets demanding German peripheral visibility requirements. This quality of reflector is noticeably more visible that non-Z standard reflectors ... seriously.
