✌ FREEME - ASTROLUX MF04S (XHP70.2) & MF04 (XHP35 HI) - BRASS@.@

I will try to re-center the emitter from my end, and try perform the test again with my other throwers.

@JasonWW

@freeme

I got 0.9778 Mcd @10m with slightly off-centered emitter for my prototype. Should be all good are some fine-tuning.

@djozz

There is not many actual measurements out there, my guess on average expect 2.1 km for a stock GT (~1.15 Mcd).

I think 20m is recommended with these big reflectors.

Any improvement on your lux reading after the adjustment?

@DB Custom

So this is the bar, can it be raised?

That is 2.08km. Not bad.

So 2.08km is the new reference for beam tuning?

@DB Custom

From closer, off-axis… the flashlight was 1.9 miles away behind me and to the left.

Is it possible to show the Nw and Cw version against that tower?

At almost 2 miles it is difficult to tell the difference in the color, the cool white just seemed a bit brighter. One was a stock light I purchased for my Son-in-Law, the other was mine with the emitter swapped.

All 3 images were taken with the Canon 5D MkIV on a tripod, same settings of f/4, 0.5 sec exposure, ISO 1600 at 125mm through a EF 70-200mm f/2.8L IS lens.

With their 124mm reflector, the Mateminco MT-35 and it’s corresponding Astrolux should equal or exceed what I saw in my GT.

Right Jason, the long distance throwers are focused for that near infinity point, to reach as far as possible, so testing them at short range is not legit… the beam isn’t focused yet. I’ve been testing lights such as these at 50M lately.

For this,I’ ve got a 65m laser distance meter,so as to test GT at 50m.

Thanks very interesting.

Do you remember if you’re cool white emitter was a higher bin compared to the stock D4 bin neutral white?

Cw did appear more clearly on the tower. Well that must be due to higher bin led.

I don’t want to assume. I just can’t remember if Dale used the same bin or a higher one. Plus with Cree’s binning method you can have up to 14% difference in output among the same bin number.

It could also be that the CW light had a slightly smoother finish on the reflector or a slightly better focus.

I think he had more details in the GT thread, but I cant find it.

I got the highest reading at 1.061 Mcd (2.06km) at 15m.
