So as the above tests for the beam pattern smoothness and angle were done with two XP-L 3000K 7A emitters, the next test and modification will be swapping the XP-Ls for the new Samsung 351D 4000K emitters, ( using two at first then four of them to measure amp-draw versus output) to compare the new High-CRI 351D LEDs for lantern use. I also hope to add the USB charger function too over the next couple weeks, ( in this case it will be TP4056 1-Amp module-based, same as the V1 prototype has, to do a longer-term test of sustainability for run times per night versus charging-times per day using four 3200mah or 3400mah cells.
_ I als owill begin working on a cross-section drawing of the new V2, but we do need to get a CAD-design drawing after that to provide to Thorfire for a base to work on.
The V2 prototype was already cool looking, now with the beam comparison I’m liking it even more, put a high CRI emitter and I might have to order a few more to donate to my scout group XD
Looks great so far. Maybe you could also add some sort of rubber pads/coating to the bottom to give it a more stable stand on sloping surfaces like camping tables. And high cri would be great.
If i remember i will try to get an outdoor photo of the lantern hung a few feet over a table. A trick i do for these situations with lanterns is place a white paper plate over the top as a “hat” hood reflector which really increases the down reflection of light.
I really need to get in on this, please add me to the list for 1 pc.
Great work DBSAR, thanks for all the time and effort you’re putting in on this!
Don’t know why I’ve ignored this for so long but I really like the way it’s evolving.
