*BLF LT1 Lantern Project) (updated Nov,17,2020)

[ToyKeeper]

I haven’t really thought about emitter choice for this project… I’m 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 it’ll be high-CRI though, and hopefully no warmer than 4000K. 219c 4000K could be good.

It’s worth mentioning that high CRI isn’t going to be as efficient.

Nichia 219C would be nice - good CRI and neutral white.

Cheers
Nico

Take care of you source of income first, so you will have money to buy more lights

[808Hi]

Interested

Count me in for a BLF Lantern, thanks!

[ssschen]

If interest list is still being updated, I like to be added to it. Thanks

I wouldn’t want a camp lantern over 4000k. The Fenix CL25R lanterns are in the 5000k region I believe. Bought some Lee filters to warm them up

Given that this is BLF, I’m willing to bet the emitter will be easy to swap if you aren’t happy with it out of the box. Hopefully we can an update on the design soon!

add me to the list , 4000k hi cri pls

Yup, I’m number 31 on the list from two years ago.

The last time I remember LED Temp being discussed I recall an XPL 3200K to 4000K being the most likely range.

While I am very excited to see this project progress, I understand that it takes time to do things right and that is the way we all want it.

[Enelooper]

Please put me down for one. Thanks!

Please add me to the list
for 2. thanks

I’d prefer around 4500K, but anything in the range of 4000K to 5000K would be okay with me, as long as it doesn’t have a sickly tint. High CRI would be nice as well. If you’re going out in nature, you might as well see it as God intended!

Interested in one.

Thanks.

Any chance you’d 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 don’t 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.

Wait, did I read that correctly?Are you really saying that blue light is artificial?

Artificial as in it doesn’t normally appear at night and messes with our circadian rhythm.

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.
