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¦.
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.
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 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!
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.
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).
Guys, did anyone disassemble the BLF version? I wonder if there is any thermal compound between the LED and the pill. In the āstockā SF-348 there is none.
Moreover, the pill is āhanging in the airā supported by spring on one side and the reflector on the led side and is not āsnug fitā into the body.
Iām afraid it can fry the led when driven off a 10440 for a long time.
