Medium Universal Lantern Diffuser Kit - Emisar D4 BLF FW3A Convoy S2+

thingiverse

This is a branching off of my D4S/D4 lantern diffuser project, focusing solely on the D4 size diffuser now known as a medium size universal diffuser due to its adapters fitting most common lights. I still have other diffusers available that may be more useful for your application. The main diffuser measures 28mm inside diameter, allowing any light up to that size in diameter to be used. If you need an adapter for a specific light, simply ask and one will be uploaded! The medium universal diffuser aims to convert a flashlight into an effective area lantern by smoothly diffusing and refracting light in all directions. Essentially, we're trying to move the light source from inside the flashlight tube to the center of the diffuser. I use a system of diffractors built into the lantern to scatter and bounce the light at the reflector's center, causing significantly more light to escape out the sides and in more directions than a simple tube or silicone sock diffuser. This project is continuously ongoing, with updates occasionally being added, including design changes, adapters, or other gizmos. To date, we have: D4 Diffuser Mk.1 - works well, taller, recommended for lights that throw a concentrated spot, single emitter+reflector lights, not ideal for the D4 but it would work. D4 Diffuser Mk.2.5 - most efficient yet, recommended all around, especially for the D4 and FW3A. Height above the light is approximately 62.5mm. Stability Stand - friction fit stand for the D4 and FW3A to increase stability on uneven surfaces or when you want to avoid your lantern falling over. S2+ size lights work okay but do not sit snug in the base. 24mm S2+ Step Up Ring - an adapter ring for 24mm diameter lights. 25.5mm FW3A Step Up Ring - an adapter ring for 25.5mm diameter lights. Update July 10, 2019: The Mk3 diffuser has been replaced with the Mk2.5, which is closer to the Mk2 design and has fewer artifacts.
