I havenât really thought about emitter choice for this project⌠Iâm not very involved in the hardware. Maybe XP-G3 would be good, or maybe 219c, or maybe XP-L or XP-L2, or ⌠etc. I hope itâll be high-CRI though, and hopefully no warmer than 4000K. 219c 4000K could be good.
Itâs worth mentioning that high CRI isnât going to be as efficient.
Given that this is BLF, Iâm willing to bet the emitter will be easy to swap if you arenât happy with it out of the box. Hopefully we can an update on the design soon!
Iâd prefer around 4500K, but anything in the range of 4000K to 5000K would be okay with me, as long as it doesnât have a sickly tint. High CRI would be nice as well. If youâre going out in nature, you might as well see it as God intended!
Any chance youâd also consider making a mini version to hang in tents?
Something like single cell (AA or 18650), candle to incandescent temperature range (~2000k), lightweight, 360* diffuser, cheap. Should include some kind of clip or ability to hang it to a tent ceiling loop.
I donât understand why people want lanterns in the 4000-5000k range. That introduces blue light which is artificial and will make it harder to sleep because it messes with circadian rhythms.
Like DavidEF mentioned the XP-G3 may be a good emitter for this. ( in the 4000K range to get the best balance of tint & output. Also maybe the XP-G3 would not get so hot as an XP-L on 1.05 amps ( three-7135s) after a hour? I never tested that LED yet⌠The run time would still be not bad on maximum-mode at 1 amp if four 3200mah or higher cells are used maybe.
