Hi,

My electric bike came with a Spanninga Kendo front light which doesn't help very much. In addition, it uses the main battery, which is a huge bonus when I ride with the battery, but I do many rides for fun without the main battery, and then I have no front light at all.

I spent hours researching models today, but I can't really decide.

Here are some details:

My current, Kendo light is rated at 13 lux by the manufacturer. That info is useless to me because I read that you can't really convert lux to lumens.
I am willing to spend up to 50 US dollars.
It needs to be one piece - without a separate battery. In addition, I'd prefer a light that uses AA or AAA batteries, but it's OK if it's got a rechargeable battery.
If 15 lux does mean anything to you, then I'd like my new light to be twice as powerful or more.
I'd like the light to be relatively small, unlike those huge "best bike light on amazon".

I have one contender, and would like to know what you think of it:
Smart BL 185 700L Front Light | Chain Reaction Cycles

There's also a 500 lumens model that's $10 cheaper.
