Has anyone confirmed the emitter bin? It looks different than my other Nichia 219Bs - a bit cooler, and possibly a bit lower CRI. But it’s really hard to tell, and could be just a matter of having a different beam shape. It’s 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 can’t 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 didn’t 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 I’ll have to include a magnet with each one, for convenience if someone wants to store it on the fridge or something.
It’s not perfect, but HJK says acceptable. I don’t take the word “acceptable” 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, there’s also the Nitecore i2 and Nitecore D2… 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, I’m 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 I’m 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 “stock” SF-348 there is none.
Moreover, the pill is “hanging in the air” supported by spring on one side and the reflector on the led side and is not “snug fit” into the body.
I’m afraid it can fry the led when driven off a 10440 for a long time.
I’ve had mine running on a freshly charged eneloop for the last hour and a half. The output is now in the moonlight range. In a previous test this morning I saw some odd behavior from both my lights. They would get very dim as the batteries depleted then suddenly jump back up in brightness before quickly dimming again. Not sure what that was about.
