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 itās 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.
Hmmā¦ thatās twice the measured output of 48 Lumen.
I donāt knowā¦
Maybe that was 48 Lumens on 1.2 Volts from a NiMH.
(letās 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 ā¦??)
A moonlight, something lowish and a highā¦ no memory, always start on ML
Other than that I still have a BLF-348 , New-In-Box. Donāt really need more.
Itās a nice host thatās 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, Iād certainly order some more. Itās 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 Iāll 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 hadnāt read that thread.
The poll shows that 2/3 would love a 5th batch of BLF-348 :sunglasses:
Very interested ā¾ā»
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.
Waterproof, please
I never got one so Yea I guess!
I have some SW45K I just got, I know there are a lot of 348 clones out there. Are any of them any good aside from the LED? Iād like to get one with a decent driver and swap the LED to make my own BLF version.
I have purchased about 50 of those lights .
Awesome light to give to friends and family .
I always load it up with a lithium primary .
I will buy more if they are like the originals , high CRI and one mode only .
