Could it be possible to make the LT1 better with Bluetooth control? Almost certainly, if it is well-implemented.
Is it really a shortcoming of the LT1 that it doesn’t feature Bluetooth control? I don’t think that is a reasonable criticism. If any Bluetooth light exists, I haven’t seen it yet.
Actually, I bet there’s more than one Bluetooth controlled light out there, somewhere, but if they don’t get the lighting features right, they will be inferior products. Most LT1 buyers are enthusiastic about it because it first and foremost gets the lighting features right. DBSAR invested a significant amount of time and effort testing and modifying a very wide variety of lanterns to determine what works well and what doesn’t to make sure it serves it’s primary purpose. The tint-shifting and highly advanced yet simple-to-use firmware add to its appeal.
Is it a dead-end? Absolutely not. The firmware is open source, and if the driver is not open source (I don’t recall), it at least is derived from designs fairly well-known in the flashlight community. Several individuals put a significant amount of their time, as far as I know with little or no pay, to give the LT1 its existing features. It’s absolutely an option for others to do the same to increase the feature-set of the LT1, such as by figuring out a way to integrate Bluetooth with the existing driver (maybe it could be as simple as piggy backing on the button input pin), or creating a new driver intended to work with a Bluetooth chip.
I’m glad you like the light overall, but it’s not fair to call it a dead-end on the basis that it doesn’t have a feature no other similar light has, on the assumption that it is simple to add. Even the features it has are not simple to create. Anduril has had a fairly long evolution of continuous improvement by Toykeeper, incorporating a lot of feedback from those of us who use it.
I want to end by emphasizing something you observed in your video: the basic functions of turning it on, or off, or changing the brightness are very easy to use. That’s what I think makes Anduril such a good user interface. It has a lot of other handy or novel features, but even though those are more complex to access, their inclusion does not make it hard to learn the main features.
