I asked for a code in this thread twice, but never received one. Whatever…
Luckely, the EC01 is now discounted at Banggood for the next 5 days and only costs 23 euro and 42 cents, so I ordered one without code.
Finally got an EC01. My first order, 5 months ago, never shipped and got refunded. Then there was the issue with Banggood shipping the wrong emitter, so I waited to reorder. Happy to report that my light did come with the 5000K emitter. A bit disappointed that they used an older version of Anduril which does not have the option to set the default starting level. I really need to spend some time learning how to reflash drivers.
