Yeah, thatâs me too. In fact, with the variable CCT option, Iâd probably want as wide a spectrum as possible. But, then, as FBsLights indicated above, the lantern would âlookâ better when all lit if the LEDs were closer in CCT. I think 3000k to 5000k will be a good range.
Also, I just found out in the new poll for Your favorite CCT for EDC that Clemence even has 2000k HI CRI emitters available. But he says theyâre expensive and not very efficient.
If the light of the leds are blended well, which should be easy with the current design of the lantern, it hardly matters how far the CCTâs of the leds are apart, the spectra just add up to produce a fine intermediate spectrum.
Going to take my name off the interest list I think. This looks like a great project and I hope it comes to fruition soon, but I donât want to wait forever, and the prohibitive cost of cells in Canada doesnât make this practical for me.
Sorry to say you were not on the interest list, in spite of being asked to be put on there.
I started updating the interest list on May 16, with Phlip at interest number 757. I think I have gotten everyone added since that time, about 60 lanterns worth.
Hope there are not too many others that have been left off, but you can always check the list on the links below. They cover everyone since day 1.
I am going to design an eight LED star based on the Q8 four-LED single channel one, but will have eight 3535 pads arranged to offer the best blending of the light tints, and have two channels to control them. ( I have a rough drawing in mind already for that purpose.
As for the other comment I agree that for some cases a tiny single 18650 lantern can work, but the advantage of this Lantern design is much longer run times & output form a lantern that is still small enough to backpack. pushing a lantern past 800+ lumens continuous on a single cell will give barely a nightâs worth of run time before it has to be charged. I have many modded lanterns that use a single 18650, but they are somewhat limited to 300 lumens or less to get a nightâs worth of run time form a single cell. Thew past test at the camp, the V2 prototype ran on maximum mode for roughly 5 hours per night, and lasted the entire trip without the need for recharging, and when i got home the four 3400mah cells still had 3.83 volts in them.
DBSAR, it might be a good idea to look at the various iterations of the Q8 dual footprint LED boards in various threads here so you can see what others came up with and how they dealt with fitment issues and such. I know yours will be different, but it still wonât hurt to see those while you consider how to bring yours to completion.
