Maybe. But I wouldn't obsess whether or not the connector is compatible. Just get the best light you can afford, installation is very easy nowadays, and if you can't be bothered, your LBS will do it for you.
I'm glad I stumbled onto your thread as I just posted a very similar thread on the Voltbike forum. I have a Voltbike Yukon 750 that also came with a Kendo+ and agree with you that 30 Lux is not enough light to be effective on unlit streets. This whole issue regarding controller specifications seems to be a "no man's land" of the ebike industry. I have searched far and wide to find out what type of current limitations my controller has, but to no avail. It is also somewhat surprising that the light manufacturers do not readily supply that type of information. The Yukon is a 48 VDC system and delivers the whole package to the light, but only uses 24ma of current. I was hoping to install the 150 Lux Busch&Muller IQ XE (about $100) which demands 7.5 watts (yes, they did supply a power requirement!). That would equate to about 150ma which still is a fairly small current draw. I also found the Spanninga Ascendo Xe on Ebay ($56) which supplies 60 Lux and looks like it truly is a drop in for the Kendo+. I'm guessing that it would draw about 50ma (key word is "guessing" as they do not supply that information). I wish that somebody in the know would be able to give us all an idea just how much power these controllers can safely supply to the lighting circuit. I would really hate to fry a component in my controller. I agree with Dmitri that the connectors are not an issue as the Spanninga (at least mine) has small spade connectors. Nothing exotic. In my opinion, the big issue is current draw.
Good, I'm glad that I'm not the only one concerned about pulling too much current through that little unknown Chinese circuit board. I was afraid that maybe I was being too paranoid about that issue. I would hope that one could pull at least a full amp through it without any problems, but that may be wishful thinking.
