Really nice light but.....

I really like this light, however a few things could be improved. At full battery all three colors are bright. When the batter losses a couple of tenths of a volt, the red is very dim, the green brighter and the white is much brighter. Each LED is set in between black plastic. This makes sense to separate the different colors but it does nothing but if looking at the one color straight on, it just absorb light limiting how many LEDs one sees. It would make much more sense if there was not plastic between LEDs of the same color or if the plastic was metalized so it was reflective surface. I have not had this long enough to see how it lasts in salt water but it looks like it will last a long time. I use this for rowing on a lake without cost guard regulations and would have preferred something that can flash.
