Would requests from fans of your firmware have any effect toward changing his mind?
I’d buy another light if it had your new UI.
And firmware is at this point what makes me interested in buying lights. I’ve got plenty of hardware that lights up generically.
(a while ago a visitor to the neighborhood lost an elderly dog — I heard people calling on the street, saw some dim orange incandescent flashlights in use, and took out four or five bright LED flashlights from my earthquake/emergency supply. They were awesomely bright, of course. Dog found, eventually)
Has anyone else experienced a bit of flicker from your D4? I have the nichia one, and I notice it especially when I turn it on after breaking the battery connection. Not the two flashes, but just clicking on. The light flickers in intensity occasionally, maybe every 8 counts often less frequent. I am using a Vapecell 1100mAh battery, it is presently reading out at 3.9V. Light is barely a day old, I have not tried cleaning contacts or anything else yet, seems like new out of the box maintenance should not be required. I notice it when the light is above or below the intensity level default after battery installation, but seems more noticeable at that point. Maybe I am imagining that, as I have only fooled around for a few minutes, nothing scientific in terms of data.
I love the UI, I would love the light more if it just stayed on at constant output intensity.
