I received my d40a in neutral white from Illumn and noticed a quirk, when I activate moonlight mode (by holding power from off) and hit the power button to turn it off it steps down to an extremely low mode that can only be seen if you look at the led directly. it is lower than the lowest mode from my Debralight sc52w. You can't turn off the light once this cycle starts because it just switches between normal moonlight and the super low one when i hit power. i have to either press mode then power, or lock the light out (physically or electronically) to get it to turn off.
Does anybody else have this same problem on their model? Should i send my light back?
I just received my D40A Neutral White, and I tested it and found the same issue. An extremely dim moonlight mode, which only occurs when turning the light off directly from the "real" moonlight mode. Turning off from the regular modes doesn't activate the "super dim" moonlight.
Maybe it only affects neutral white versions of this model? Anyone else notice it?
It doesn't concern me, with the possible exception of it increasing the parasitic drain. Has anyone else tested this, and measured the current draw from it? This light is tricky to set up for current tests, so I haven't tested it myself. But based on my Zebralight SC52w-L2, it has a draw of 2mA on the lowest moonlight. So, the D40A has to be quite a bit less than that.
Probably not an issue, unless it's in storage for a few months, but I'm curious to know.
I'll see if it's bright enough to use as a locator in the middle of the night.
Update:
It does work as a locator for a very dark area with fully night-adapted eyes. But, you have to be viewing at least the "spill" area of light. The "hot spot" is actually quite bright when looking directly at it, but that's because it is so focused. Obviously, you can't illuminate anything with this "ultra firely" mode, but if you place the light aimed at you before going to sleep, you'll be able to easily find it.
The brightness, when looking directly into it, is about the same level of brightness as a GITD indicator after a few hours. However, it looks brighter, because it shows up as the entire 40mm lens.
I have noticed that it appears to enter this "ultra firefly" mode when shutting it off on modes other than moonlight, especially if it's been on for awhile. In these cases, it appears even dimmer. Very difficult to see, but possible with dark-adapted vision and looking closely right into the lens.
I wonder if this is a consequence of how Sunwayman designed the electronic circuit. Maybe the same current needed for the electronic switch is also still going through the LED?
