When ALL of your high output (big reflector) lights are measured so low, whon’t you think it might be due to the way you measure, the distance, or the light meter itself?
I bought an Extech 450HD because my LX1330B was……unreliable to say the least. Depending on battery voltage it would measure either to high or to low, or constantly dropping during testing.
The Extech is very reliable, although it measures around 10% lower then Djozz’ Gossen Mobilux.
Knowing that, I can compensate.
Just giving you my experience with throw measurements.
Yeah it is amazing to see how far the manufacturers have come. This light still puts them 200-300Kcd away from the DEFT-X. They still have a fair ways to go to catch up to my Victor Enthusiast though;) 1.3Mcd. But then I’m on the move again. Working on a new class of throwers.

As I understand,most of us have the cheap HS1010A LCD Digital Light Meter.Have you compared your Extech meter with this cheapie?
I have two of them,one HS1010 plus a HS1010A one, and I see that they give the same reading for a light,which I think says something about their reliability.
Has anybody observed their NW TN42 to appear pretty warm? Is that sure evidence that the LED is being overdriven? Does that mean the CW will look NW instead?
Actually I like my TK61vn V4 better. For several reasons.
Much nice beam profile,no rings, less artifacts, more defined hot spot, more spill and does NOT get as hot. I am not mentioning the tint because I chose the cool white[mostly becuase of a little more output!] The PDT tint on the TK61vn is warmer and very nice.
I am getting a holster that will work for the TK61 and TN42. Was made for the TN42. I am looking forward to getting it. One thing about the straps.
The design of the strap and how it attaches is superior on the TK61.Both ends swivel, scratching is at a bare minimum w/ TK61 and you do not need a ring to attach to the tail cap hole. That attachment for the TN42 constantly gets stuck while the pivoting attachments for TK61 have no issues whatsoever.
None of this will matter when I get my Holster from HKE next week! :+1:
hmmmmm. Just started looking at this thread. Mine is also marked like yours.Theirs in not only marked in a different location, but they separate Thrunite and TN42! I think that means OURS has a bit more output! I know mine does[VN]!
Hold on a second! I found something on my tail cap that neither you or Taschenlampen have!
Is all that throw very useful, especially with a narrow beam? Doesn’t atmospheric scattering (especially with cool white) limit how far the beam can go, and how well you can see “around it” (with all the light being scattered back)?
I don’t have any LED lights approaching anything like that kind of throw, but I used to have a 200w spot-light that would throw like that. Since it wasn’t LED, it was large and heavy and impractical, but it sure threw out a wall of photons. So, I understand the fun part, but is it really useful?
