Yeah, it seems like saabluster disappears for periods of time from CPF. I bet he has many irons in the fire that take priority.
It’s true. I have too much going on to be honest. Not being modest so I am reducing my current responsibilities. Currently working to get some of my past years research into a salable product that I am proud of. More to come.

Thanks for the update. Many people are anxious to see what is beyond the TN42 from you. :)

Michael probably needs to move on to the BLF Gigathrower with a HXP35 Hi that gets 1.2 million lux and puts over 2000 lumens down range.
I’m well aware of the project. While one can always get more throw going larger and larger true progress in my eyes is increasing specific performance. That is the fundamental technology must improve such that a light increases in performance without gaining in size. It is fundamental technology improvements I have been seeking for over a year now. That is why I haven’t been releasing light after light.

+2

Anyone with some knowledge can keep increasing the size of the light[reflector] to increase its throw.

To be able to increase the throw in a light of the same size is much more impressive, challenging and ground breaking.

I was considering buying the BLF Gigathrower.

However, after having read the last few days of posts, I'll respectfully decline and wait for Michael's 2-3 million+ candela version, the same size or smaller.

First of all, I do like the TN42.

I have found in real use it slightly under performs with comparison to K40vn or BTUvn Shocker, which might just have more lux within the hot spot. IDK.

The hot spot on TN42 almost drowns out your vision which is a compliment and maybe a fault in real use. I tried all 3 outdoors in my dad's field with a tree line >= half mile out and the Shocker was probably best performer visually. No significant difference in the tree line almost a mile out but it's hard to say for sure from that distance. Plus it has been a few days. Fully leaved trees are hard to see, bare trees bounce the light back a good amount. I'll have to head back to the field.

I don’t want you to have outsized expectations right now. My goal is first push the TN42 to its limits. Just finished a key component a few minutes ago. That said I am not ready to say where it will end up performance wise. Of course I always aim for the best performance on the market. :thumbsup:

Michael, I understand.

I was only saying that you could probably produce a flashlight with twice the candela of the BLF Gigathrower, if your flashlight were as large as that. It may not use the same LED or reflector, may have a giant aspheric, or some type of collar similar to a Wavien one, but I'm sure you could do it.

As to the TN42, I'm eagerly awaiting the results of your research.

Michael,

How about using the "OSRAM OSLON Black Flat"? I don't pretend to be an LED expert, but this seemingly can produce very high radiant flux in a small package.

The lumens are only 800 or so, but Vinh pushed one of his reflectors to 1.1 million candela using the Black Flat. It would be a pencil beam, but I'm wondering if they make "larger" LEDs using the same technology.

That would be nice if they could make larger LED'S or ones w/ larger hot spot and more lumens.

It is hard to find the right balance b/w great throw and enough peripheral light along w/ heat management!

Personally I have NO interest in these pencil beams that have 700/800/900 lumens and go over 1 mile. The SST40[even though I am not fond of the tint] pushes my TK75vn to 7700 lumens[30 sec] and 420Kcd. The heat is NOT an issue now that it is close to winter! 27F last night at 6 pm.
