Nice! A lot of light still hits the ceiling, how about an inverted cone or curve inside the cap to reflect more of that light sideways or downsince most of led output is directed near 90 degrees from the die plane. You will still get upward spill from what misses the cone.
Or get creative with a center led and tir optic by leaving the cap open to the tir for beam and the surrounding LEDs scatter light from the outside of the tir. Using something like the 32mm quad Noctogon as a base plate. Cool what you’ve done though.
I been experimenting with various reflectors & LED positions to get the light in all directions as evenly as possible while eliminating as much eye-glare as possible. so far the down-firing LED, with lightly frosted diffuser and a lower flat-white reflector seems to work great with getting the light directed both up and down and out the sides evenly without having the LED in direct view that causes glare.
Very interesting project!
Do you think the reflector could be made easily interchangeable and available in colors like red or green ? I wonder how much luminosity would be lost but it might also help not scaring wild life to come closer as well as possibly not attract as many bugs as regular light ?
That sounds perfect. I’m very excited about this project and really hope that we see a group buy in the near future. I will more than likely order several for myself and friends and family assuming they are solidly built and perform like your pictures. Thank you for putting in all this time and effort. I currently have ZERO lanterns that I actually enjoy using and dozens of flashlights and headlamps that I love.
If it is not too late, it will be very beneficial to incorporate built in charger to recharge the battery.
This enable us to use Solar panel with usb output, so the battery can be top up during the day.
It also saving us having to bring separate li-ion charger during camping trip.
But to think again, this idea might not be feasible as the origina host need to be modded extensively to incorporate this feature
4056 is good enough as it is very reasonably priced and provide 1A (10w) max current to charge the battery.
Even 10w solar panel is still quite bulky nowadays (about 20% max efficiency), unless we can have access to reasonably priced triple junction solar panel which are used for space application (approaching 30% efficiency)
Count me in on this more and more exciting Group Buy…
