I wish the lantern project would be a sort of addon to the Q8, I am sure with a proper reflective cone shaped on the top with a milky cylinrdical diffusor the light pattern would be great, without moving the LED on the top
Just screwing the diffusor on the Q8 instead the bezel
Lexel such questions are asked many times
This is a lantern with different features.
Every time somebody says a diffuser or add-on for the Q8 suffices this will probably be the response
Have tested more of the diffuser designs that I wished to count, (and abandoned all of them) some are ok, but not nearly as beneficial as a down-firing design for lantern use to minimizes eye-glare from the angles that most lanterns will be used. As Miller mentioned it’s a question that been answered many times. One example is i have a head i built to fit on top of a BLF SD-10 ( and other lights with the same sized head) that is very close to your drawing, but like most all types of flashlight diffuser heads of that style, sens eye-stinging glare to the eyes when carried like a lantern by a lanyard, or on a table that is lower than your horizontal plane of view. ( example, when resting on a low table beside chairs at a campsite, or a coffee table, when you look down at it you get the direct view of the LED and its piercing glare. ( which is even worse with the colder tints higher than 3700K.
Bluetooth remotes would just drive the price way to high, and to complex and a feature that many would never use. I have a couple remote control lanterns and the Manker Godmes Bluetooth flashlight. A feature rarely used.
