Our conclusion The sensible cheap answer. Approved, replaceable cells, and the shortest runtime here — which only matters if your rides are long.
DANSI is an Italian brand the manufacturer dates to 1918 in Varese, and this is its entry battery light set.
What the manufacturer publishes
Thirty lux on the bright setting and 15 lux on the economy setting. StVZO approval for German road use. Approximately 6 hours of front runtime and 15 hours at the rear. A battery-level indicator. Tool-free mounting with the supplied bracket.
Why lux and not lumens
An approved lamp is specified in lux because the approval concerns the beam: a defined cut-off at the top so light lands on the road rather than in oncoming eyes, and a stated illumination at distance. Thirty lux with a shaped beam is a usable town light. It is not comparable to a lumen figure on an unshaped lamp, which is why comparing the two directly is the most common mistake in this category.
The battery argument
Replaceable cells never leave you unable to ride because you forgot to charge. Against that, they are a recurring cost, and the battery-level indicator here exists precisely because a battery light gives less warning than a rechargeable one.
Where it sits
The lowest price in the hub and the shortest runtime. For a bike used for short trips in town, that combination is entirely reasonable. For a commute of an hour each way in winter, the rechargeable sets above it are the better fit.
What we rate and what we flag
Strengths
Replaceable batteries, so a flat light is solved with a shop rather than a charger
Two output levels, 30 and 15 lux, with a battery-level indicator
The manufacturer states StVZO approval, at the lowest price in the hub
Compromises
Six hours of front runtime is the shortest here
Batteries are a running cost and a disposal problem the rechargeables avoid

The questions riders ask
How long do the batteries last?
DANSI states approximately 6 hours for the front lamp and 15 hours for the rear. The front figure is for the brighter of its two levels.
Is it approved for German roads?
The manufacturer states StVZO approval. That is a manufacturer declaration and we report it as one; this site does not assess conformity.
