V54 Lumen & Lux Measurements

The data below is certainly not 100% accurate and every light vary from sample to sample. However these values should give us an idea of what to expect. If they off at least they are all relatively off ;-)

Note to Wayne:
All values adjusted with 7.4 correction factor

Re: V54 Lumen & Throw Measurements

Yeah I agree. Like you said though, no matter what, moving forward they will all be comparable. I hope you found it not to time consuming and enjoy it because I love reading the numbers. I hope you add lux numbers. Thanks for your hard work.

Re: V54 Lumen & Throw Measurements

nice vinh! I would leave the numbers alone even if they are in fact 50 lumens high - numbers will be relative and when you end up with tons of lights tested they will all compare nicely to each other.

Niceee

Re: V54 Lumen & Throw Measurements

50 lumens is nothing when you're talking about lights with these kind of outputs

Re: V54 OTF Lumen & Throw Measurement

So what do you guys think? Numbers on the factory lights seems a bit high. About 50 lumen high may be?

May be just subtract 50 lumen from all the numbers to be safe?

If you are using the same factor as Justin, maybe it would be best to leave them alone so they're all comparably off the same.

I would love to see candela numbers, it's half of what tells me what I can expect for beam profile (the other being beam shots)and helps me decide which light to buy depending on what I need.

Companies like Eagletac and Zebralight list beam angle but since you don't, CD #s and beamshots whether video or photo) suffice nicely.

Re: V54 Lumen & Throw Measurements

That is a starting point and the stock numbers seem relatively close,that is all that matters. Like Jmpaul said,,the numbers will all be relative/consistent across the board as you measure more and more lights. Pretty soon you will be a Selfbuilt Jr./Jmpaul Jr.!

Good Job!

Re: V54 Lumen & Throw Measurements

YES!! Sorry sir, that was a grammatical error!

I don't want to hijack Vinhs new thread,,, But I found someone selling[on here] the SAME host as my soon to be SL2c!! I hope Vinh has Copyrights!

 

[Skylumen]

Re: V54 Lumen & Throw Measurements

Alright great! I will continue to measure like so so all the values are relative.

The host is open to all. The electronics such as DriverVN2 or my warranty you could only get from me.

I was just looking at new posts and clicked it! ....It caught me by surprise!


That makes sense........Your mods[DriverVN,PDTc,current boost, ect.] are what makes yours that much more special.

Re: V54 Lumen & Throw Measurements

Post 1 updated. I increased the correction factor to get a lower value. I like lower readings more than higher readings. They worry me.

Re: V54 Lumen & Throw Measurements

You going to try and do lux readings to Vinh?

Re: V54 Lumen & Throw Measurements

Any update on lux when you're back?

Re: V54 Lumen & Throw Measurements

Hey Vinh-
Have yer dad throw the SK98 on the lux meter when u get a chance.
I'm thinking it's gotta be ~30K at least.

Luxis harder to measu re than Lumen. One small bad technique and the numbers are off by a lot. I will start posting numbers When I feel confident with my set up.

The important things to remember on Lux, to get a representative cd, is to measure it far enough away so that the beam has had time/room to form.

IE: The cd is the lux at one meter, but, measuring the lux AT one meter is almost always wrong to get the cd, because for the throwy lights, the beam may not REPRESENT the true cd until it is even 20 meters away.

We want REPRESENTATIVE cd values, because we use the cd to calculate how bright the spot will be on distant targets...to know if we could SEE SOMETHING at those ranges.

If the cd can be plugged into the calculation, and predict the lux on a distant target, its a good number.


Generally, the best way to FIND the representative cd (What the ANSI methods are supposed to be telling you), is to measure the lux at the brightest part of the beam (central typically) at various distances to find the distance at which the cd stops rising/levels off.

The lux will tend to drop as you move further away from the light (Due to inverse square law), but, the cd can rise even as the lux drops....because the cd takes the distance into account.

For most of the lights, if measured at 20 meters for example, the beam will have formed by then. Just multiply the measured lux at 20 meters by 400 to get the lux at 1 meter (the cd).

So, if you get 250 lux at 20 meters, that means the light has a cd of 100,000, and so forth.


For your lux meter, generally, it will be most accurate at the central part of its range/range with best resolution...so, typically, a more distant reading will reduce the measured lux to the meter's best resolution.
