Noctigon K9.3 (Nichia 219b sw35) Flashlight Review

Noctigon K9.3 (Nichia 219b sw35) Flashlight Review

The Noctigon K9.3 is a feature-rich flashlight with many emitter options – seen here in Nichia 219b.  USB-C charging, Anduril, backlit e-switch, and a secondary channel, to name a few!  Read on!

 
 

Here’s a link to the Noctigon K9.3 Nichia 219b product page.  This is not a referral link.

Versions

Three body colors are available.  Black, Dark Grey, and green (seen here).  All of these bodies offer the same feature set.

There are really too many options for those three bodies to mention. Here’s what’s listed for the main channel.

Here’s what’s listed for the secondary channel:

I believe any combination of those two groups is possible.  And very often, the proprietor of intl-outdoor.com will do custom or special emitter options by request (and for a small fee)…

The options are really practically endless.

Price

As seen here, the Noctigon K9.3 Nichia 219b goes for $134.58.  That’s with the additional cost of the Nichia 219b sw35’s, of $9.90, and an additional cost for the deep red secondary channel, of $6.  You could step all that down and get the base light for around $120 if you wish.


Noctigon K9.3 Nichia 219b Flashlight Short Review

Typically the reason I do Friend Fund Friday reviews is that I know I won’t be buying the light myself (and have it fall into the Fun Fund Friday category.)  In this case, after much user input, I’m trying to flesh out my “Hank Light” category by reviewing more Emisar and Noctigon flashlights.  I might end up with an exception here.  I love this light.  It’s smaller than I thought based on photos I’d seen, which is a big plus.  It’s got so many features that just make it incredible – and they’re all good features.  As in, they’re all perfectly implemented.  This is a fantastic light.

^ Measurement disclaimer:  I am an amateur flashlight reviewer.  I don’t have $10,000 or even $1,000 worth of testing equipment.  I test output and such in PVC tubes!!  Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).


There's more at my site, including runtimes and all that other good stuff. Head over there if you're willing, and if the table above doesn't satisfy your need for data.

Thanks for the review. I find the runtime graphs interesting in that the “next highest” mode (6/7) has quite a big step down during the first 10 minutes. Any reason for that behaviour which is quite different to the more stable DT8 runtime graphs?

I’ve been trying to think of a good answer for this, and my best answer is really “I don’t know.”

Do note that mode 6 on the K9.3 is aroudn 5.5A and only around 3.65A on the DT8. I expect that plays a role.

I wonder if the FET is coming into play in these mode groups? That could explain step downs that are not evident on the no-FET DT8?
