This light still tempts me. I just can’t get into the super bright but not too efficient SFN55.2 LED’s.

It’s super tempting so I just went with the sft40s instead. It’s a mk38 on 1/3 the budget, you get more throw at the cost of a half the lumens but it’s only precieved brightness.

From 1Lumens Nightwatch NS73v1 review I calculated the output to be 4131 OTF lumens for 13,7A. Divide those amps by two and we are near the 6V XHP70.2 territory. Not too inefficient in my opinion.

The Chinese Leds are actually quite efficient at low currents. However, they can take ridiculously high currents and therefore become inefficient at those levels. You can just choose to not drive them so hard. Other Leds such as Nichia Leds will just blow at higher currents.

Hi all

I just got the NS73V2 and I am using a Samsung 30t but would be the difference in terms of output and max lumens if I used the Lishen 21700hp battery?
I am trying to get it from Neal but I have to buy another light first which I don’t want to!

What is the recommended battery for this light?

Thanks

I like torches Smile

Samsung 30t will give you the max lumens.

I just pulled the trigger on the sfn55 3000k JKK76, from kaidoman. Really looking forward to seeing a > 20,000 lumen light with 3000k LEDs. 

I have my expectations set realistically, I have modded and bought enough LEDs and Flashlights to realize the tint might not be great and probably isn't, and also it's probably not doing 30,000 lm with 3000 K LEDs. Regardless I feel like I'm in for quite the treat at $92!!

Especially after selling my MK38 Sft40 which I regret. 

and I order probably $100 a month from kaidoman in LEDs as They have some great ones (hi cri xhp35 HI , 70.3 and 50.3 HI, hi cri) and they're free shipping and pretty quick shipping is never disappointed me. And they've never messed up an order. They're a great site to deal with! 

Great......it's just for fun and "special feeling". I hope you are not a sole purveyor of tint or CRI / R9070 or those things, coz it wouldn't be nice / natural looking. But if you want something special + fun, this is gonna be it, just because like i mentioned above there are very few lights that are 3000K and are floody throwers, or are gonna be f***ing costly. There are, of course as you'd know it, tons of lights in the 1000 to 2000+ lumens range at 3000K. I like high CRI lights in a way but i don't chase this route endlessly as it never gels with high output. I measured over 20k lumens output, in fact raw numbers on the light meter would be like 2200 lux for the 3000K and 2500 lux for the 6500k version. This is a very small gap between 3000K vs 6500K, usually the difference / efficiency hit is much bigger, and it's likely that the LEDs are all driven the same. So definitely the tint/CRI/look won't be like your Philips or even Opple LED bulbs @ 3000K. This is pretty yellow, but no green stuff at any of the modes. It is also very workable and mimics incandescent at output levels 1 and 2 with a ceiling bounce, so it's not without its practical uses. ps. I measured this to be 130-140k cd range. Not a true thrower kinda territory, but it is not shabby at all. Just only like 3 years ago I and quite a few BLFers were excited with the Sofirn Q8 at 90-100k cd, even though it was just 5000 lumens.

 

I don't know if it was discussed further, but I finally got an Opple after receiving this light. The JKK76 with 3000k option is in fact 95CRI.

 

i already sold my light, just bc I'm obnoxiously sporadic in selling things, but the day I packaged it up I realized I never tested it. And it was in fact Hi CRI. 

that would've probably stopped me from selling it had I tested it before I was paid for the sale lol.

 

Anyway, the 3000k JKK76 is a MARVELOUS light for under $100.

FYI. If you go to Kaidomain and type in Jin Heng or JKK. it does not show the JKK76. But, if you type in JKK76 it does show and can be added to a cart.
Go figure….. Smile
