First time for a Nichia 219B ~4500K. Looks great, lousy at beamshots, plus all the tint issues between camera settings and monitors.
The colors look good to me, but I am not an aficionado of the āpopā in colorsā¦.
Beam profile is about a 4 foot hot spot at 10 feet away, plenty of spill. Ran it on a LiFePo4 10440, got warm, not hot. The protected trustfires do not fit. Output increased about half again on LiFePo4ās.
It is a great little light, the thing is a benchmark for single mode penlights. Good balance on everything, the tint is wonderful, at least to meā¦.
I got mine yesterday. Very nice lights overall.
Has anyone confirmed the emitter bin? It looks different than my other Nichia 219Bs - a bit cooler, and possibly a bit lower CRI. But itās really hard to tell, and could be just a matter of having a different beam shape. Itās amazing how much the optics affect how the tint looks.
In any case, theyāll make nice gifts.
Glad to hear people are getting their lights and generally happy with them. :)
That's right. Earlier 219B was 4500K, this "NVSW219BT-V1, sw50, R9050" is 4750-5250K. I have been noticing some variation in the tint between different samples, but they are roughly the same => I'd say 4750 to 5250K is quite accurate. (Don't have means to measure the temperature accurately, sorry!)
Emitters to this GB came from IOS, so I'm pretty sure they are as advertised.
I tried to resist this gb and it was a success for a long time, but I finally caved in and ordered one
Thanks/kiitos =the=
Ah, okay. That makes sense.
Itās quite a bit cooler than my 219A lights, and only a little bit cooler than my other 219Bs.
The unfortunate part is that itās not as easy to gift eneloops and chargers along with these nice lights.
As a recent joiner to blf I missed out on the 9.99 price, dang
Tempted as an introduction to hi cri lights still though
Look at the first post.
You can still order these lights with the coupon code.
Iām gifting mine with energizer lithium cells.
Got my lights yesterday. All I can say is wow.
I was on the fence about this one for a long time but I finally gave in and ordered one. It arrived just as I was leaving town for the weekend. This is a gorgeous little light. Very sleek and classy. There is a very satisfying click from the switch. The machining is so smooth you canāt even see where the tail meets the tube until you unthread it to install a battery. The beam profile is great for a light this size. Nice floody pattern with a subtle hot spot and the tint is a warmish-neutral beauty. I honestly didnāt expect to be very impressed with this light but I most humbly admit I was wrong. This is a sweet little light and perfect for gifting! I will try to buy a few more while I can. Well done!
Hereās a white wall, from ~1m (tint in pic is not accurate vs. actual):
Yeah, I put in Energizer lithium primaries when I give these away.
Itās the decent thing to do.
I donāt know of any budget one-AAA NiMH charger.
Anyone know of an appropriate board that could be put in a simple box?
Most of the ideas are from years ago, and charge 2 cells at a time, I guess thatās simpler? E.g.*
*Someone asked me recently what āE.g.ā means.
I told him it means āExample from googleā
I am a bad person.
Xtar XP1 is a Li-ion and NIMH charger that you can find under $10 online. Is there anything wrong with that one?

Not ideal for giveaway with AAA cells. Thereās an updated āXP1 Plusā ā I havenāt seen a review of it.
It seems that both the clip and the body of this light stick well to magnets. I think Iāll have to include a magnet with each one, for convenience if someone wants to store it on the fridge or something.
Itās not perfect, but HJK says acceptable. I donāt take the word āacceptableā to mean dangerous or bad, and I feel it would be more than ok for a gift. Probably better then most chargers included with NIMH batteries.
HJK does, at the very bottom of his discourse on proper NiMH charging, set out criteria to define an excellent NiMH charger.
Battery charging NiMH [image] This article will look at the different charge and termination metodes for NiMH batteries, their advantages and disadvantages, last I will show some detailed measurements from charging NiMH cells. Generally about charging AA/AAA NiMH batteries are usual rated for charging up to 1C, i.e. same current as their capacity. This means that a charge current of 2000mA (or 2A) for a 2000mAh battery, most chargers will charge with a lower current, but there isā¦
Examples satisfying all criteria are yet to appear. Many come close.
For gifting along with one AAA Eneloop ā well, this takes four AAA or AA cells ā good way to convert the giftee to using more NiMH in other devices, I guess.

For quality cheap (~$10) chargers, thereās also the Nitecore i2 and Nitecore D2ā¦ I feel comfortable with how safe they are to gift them for sure. NiMH is a pretty safe battery to begin with.
FWIW, I measured two BLF-348 units. I got 48.6 lm and 49.1 lm at start, on a fresh Eneloop.
So, just a bit under 50 lumens on a rechargeable NiMH cell.
As for runtime, Iām not sure. It took about a day of frequent use to drain the cell I had laying on my desk. So, a bit faster than Iām accustomed to, and it gets warm during use. I get a few weeks per charge on my 10180 lights, but I only use them at a low level (~10 lm).
Usps tracking shows that mine hit sanfran. Should be here soon!!! :D
