Thanks. With regard to reviews, I tend to treat them with much caution. At times people make authoritative statements while they deal with a second light in their life. At other times people consider conditions that are removed from mine. Often I own the same product(s) and my opinion is quite opposite.

I've been through maybe 15 different B&M rear lights on different bikes and only one model had a moisture problem and in that not LinePlus for many months by now in the rain on my main bike. Nearly all worked fine in terms of an adequate illumination. In fact, there was no problem getting a decent rear illumination already with incandescent bulbs consuming only a fraction of the overall power in the dynamo system. LEDs brought better efficiency and reliability. Still new innovative solutions, such as what Lumiring seems to be can be worth checking out. (LinePlus seems to employ a similar solution weighted more towards purpose, relative to show, than in Lumiring.) Current is important for me, because in my main system I can direct any excess power for charging of backup batteries - important in winter when you may need to ride with lights on at all time and additionally ride slowly. Price is important with regard to a number of bikes. On one bike I can do nearly anything, but not on 5. Anyway, for one bike I may try out Lumiring if I have an occasion to get it at the lower end of its price distribution.
