The Lumotec IQ-X E has 150 lux output. The on board power supply voltage can be anything from 6 volts to 60 volts. The headlight connection must provide a minimum of 7.5 watts.
The IQ-X E has the same shaped beam as the dynamo powered IQ-X. It's just half again brighter.
The IQ-X E does not have connectors for a taillight. The taillight will have to be wired directly to the e bike's controller, along with the IQ-X. And the taillight you choose must be able to handle the voltage provided by the e bike for lights.
