I don’t understand most of that either, but top right > CCT: 4739K
Aha, hadn’t spotted that yet, thanks.
I like this light for the simply stile
But I would prefer model with pillar screwed on body instead a P60 host
Led suffer Heat a bit
Yeah, you mean the thermal path is just as lousy as a P60 light, because the 348 uses the same construction to hold the pill in place…
I guess they do it for easy production because it will always fit like this.
Head of my 348 nichia begin hot fast with fresh alkaline AA (1,5 ampere at tailcap measured)
that is normal current?

Sounds a little high to me, but probably it’s normal.
1.5 Volts x 1.5 Amperes = 2.25 Watts x 75% efficiency of driver (guesstimated) = 1.7 Watts to the LED = approximately 170 Lumen x 60% efficiency of the reflector and lens = 100 Lumen light output.
Hmm… that’s twice the measured output of 48 Lumen.
I don’t know…
Maybe that was 48 Lumens on 1.2 Volts from a NiMH.
(let’s say 1.2 Volts x 1.2 Amperes = 1.44 Watts x 75% eff. driver = 1.1 Watts to LED = appr. 110 Lumen x 60% eff. optics = 66 Lumen …??)
There won’t be any changes, sorry! The light will be exactly the same than in earlier GBs.
If enough people are interested in more complex light (more modes, maybe different tints), a separate GB can be arranged.
A moonlight, something lowish and a high… no memory, always start on ML
Other than that I still have a BLF-348 , New-In-Box. Don’t really need more.
It’s a nice host that’s proven fairly reliable. My biggest long term concern has been the switch but they seem to hold up pretty well. Given that they have made a classy, reliable host that is mod friendly, I’d certainly order some more. It’s not perfect but for what it does already it ticks a lot of boxes. A must have for modding or off the shelf edc. The upgrades in quality needed to make it superb would take it out of the budget realm.
Some data with the tiny10 dd*:
Low - 200 mA
Med - 600 mA
High - 2A
- cell at 4.1V
Since this is for pops I think I’ll change it to a tiny10 - 7135 with two chips instead. Should be 86mA, 250mA, 860mA which is more reasonable. He tends to yelp a lot.
Nice work RBD. 860mA sounds very reasonable. :+1:

Hi is a group buy still on ?..
I need a few.
Thanks!.
The group buy was along time ago.
Thanks David. I hadn’t read that thread.
I don’t promise anything…
The poll shows that 2/3 would love a 5th batch of BLF-348 :sunglasses:
Very interested ⒾⒻ
single mode like the original
on/off only No mods
nichia219 B or other Very high CRI nichia led BUT NOT the nichia C
AAA / Li-ion support
very very bright (as bright as possible)
keyhole
very good clip
very good switch
perfect fit and finish
water proof
The exact same design but just a little bit smaller
cheep
If yes then in for 6-12 light
Please do this, with nichia and 1 other higher out put sst/ Cree option. And hi/ low mode, like olight i3t eos aaa
I would be in for more!
Hi/lo has been discussed before. The consensus was that adding hi/low priced the light out of the price point. If you want a AAA light with hi/lo look at the Sofirn C01S.
I could see a new run of BLF 348s. They are just right for low-cost gifts.
