Hi guys, i’m about to measure my lights, 2 of them are modded.
TK75 current bump 3>4.6/4.7A
TK61 dedomed only for now.
I need some reference points of users who did the measurments on this lights, before and after the mods or even on stock.
Anyone with HS1010A meter can give me the settings/mode and on what distance did you measure your lights, and what results you got? thanks.
Anyone?
I ordered the same meter at banggood last week…
if it’s here we can compare numbers…

Good to know, thanks!
Measured this…
@10 meters = 2800 lux. TK61> dedomed no current bump yet.
280kcd sounds a bit low for a dedomed tk61. Might see benefit from some adjustment.
Its stock light, no current bump 
I’m sure it will come close to around 550.000cd which is very good when we bump it to 5.75A. Not Vinhn very good, but more then enough for me 
I have the HS1010 and after a lot of testing, I found it UNDER-measures by approx. 10% (my sample, anyways).
One thing you have to be careful about is centering the sensor at the very brightest part of your light’s hotspot.
On my de-domed XSearcher, I’m measuring about 370-380Kcd at 10m.
Could be, we compare mine to other meter, and the other was showing around 2-5% higher. Anyway, i need some general numbers, being 100% accurate is not what i really need or want
I cross-checked the readings with my light-meter (Sekonic, for photography-use) and yes, it’s a little under-measuring.
I actually put my lights on a chair, 5 meters from my front door.
I then take the light meter and use the """MAX mode """and move my meter through the hotspot on the door.and the MAX mode means it will measure the MAX lux..memorized that...that's the easiest method for me. That way I'm not moving the flashlight, which would probably result in higher numbers.
why would moving the light give higher numbers than moving the meter?
Because the meter touches the door, and you slide it on the door. Therefore distance won't change. Light stays on the chair..
When you are standing and holding the light, you will change the distance between the light and meter..because your hand and body will move..
Not a big difference, maybe just a few centimeters.. but my method will just be a little more precise..although not the most precise...if you have a special stand for both the meter and flashlight that would probably be even better.
Just sharing my ideas of doing these tests. We are here to learn from each other and share different ways of doing things, that way we are helping others.
If you have your method ,please share maybe someone can copy yours.
in theory there would be “better” ways, but i think your idea gives an optimal way to do that measurement in real world (by non scientific guys ;))
the only thing what comes in my mind ist that the light has to be positioned in a way thyt the beam hits the door in 90° angle
Both my flashlight and my light meter are locked in position. Therefore the distance (measured carefully) does not change.
I use the same meter, with a “set” perimeter of setting in this Lux Sphere to get my measurements. I now have it calibrated & calculated to be quite accurate based off of known ANSI measured lights.
Dbsar, when I first saw that sphere I was like WOW...crazy stuff there. Looks pretty cool.
I don't think I will go that far..I'm quite happy I can now compare ceiling bounce etc with runtime to see how the light performs..
Maybe 1 day I want to get a sphere, but I need to move house then.. we don't have much space.
i have one hs1010 and i only measure at around 3.3 m and what i see in the meter i just add an 0 and its done for me, pretty easy method because i am lazy 
I think one purpose is to see what the lights I own are capable of and how much the gain after a modding is…
comparing with others is a different thing, but I am sure within 5% it’s okay for everyone when measured in a comparable way…
got the meter today!
can someone give me short instructions how to measure:
*Lumens (ceiling bounce)
which distances should I use?
*lux
3m distance - aim on the meter to get the highest reading (using max für kein maybe?)
ad a 0 to the reading to Calc @1m?
any other tips?
