Olight X6 marauder

[Dreammachine]

A me considerando il prezzo non piace è grossa pesante ed al max puo stare solo 10 minuti poi è veramente flood, non riesce a convincermi.

Olight SR95UT 192,300cp 1300 lumen
Olight X6 126,000cp 5100 lumen
Fire-Foxes 3 224,000cp 4000 lumen

Una torcia del genere nascie per essere principalmente flood, per lo scopo a cui è destinata è eccellente (secondo me) di certo non la usi per le uscite domenicali ma ha un utilizzo più specifico. Peccato non possa essere alimentata direttamente a 12v, questa secondo me è una grande pecca.

La disamina di Budda mi sembra attinente ; pure a me non tornano
i Lux/1m. della Marauder dalle foto... mah.

[fatigus]

olight non dichiara dati falsi
visto il costo dell'oggetto credo ci sia una progettazione seria alle spalle la king no copiata,assemblata e se funziona va bene se no

[Budda]

quindi mi confermi che un xml in una parabola fa 18'000 lux. e come mai altre torcette a stento arrivano a 5000?

[dorgabri]

Budda ha ragione.

Dai beamshoot si nota tantissimo la differenza di luminosità.

[P.P.]

L'unica sarebbe trovare un esemplare di Marauder e poi
fare una comparativa.

io non confermo niente non sono ne un ingeniere ne un tecnico mi baso su quello che vedo


e un po di comparizioni olight x6 sr90 ecc

stanotte ho pensato che se una torcia flood ha 1000 cd, se ne metto 4 una in parte all'altra, avrò più di 4000 cd nel punto più luminoso.
Questo perché all'hotspot di ognuna (1000x4) si sovrappongono i 3 spill.

Quindi, per fugare il mistero dei 104'000 lux/m della marauder, ho scritto a uno che la marauder ce l'ha

Hello SelfBuilt,
I noticed that you measured 104 k lux with the marauder. That's a lot of throw!
I always loved throwers and owned many of them... but with this light I noticed something "stange": since all the led have the same reflector and are driven to the same current, it means that each led+reflector throws 104'000/6= 17'333 lux .

Given this hight number, and knowing the very flood emitting profile of the XML, coupled with an OP reflector... I have difficoulty understanding how a single XML would generate such a lot of Cd

From the pics I've seen I made some calculus and my results are that each reflector is comparable in size with the reflector of an XML in the King 3xXML, the reflector diameter for the X6 should be around 3,2 cm while the king is around 2,2 cm (confirmed from actual measurement). Can a reflector 1 cm bigger increase the lux of every led by 266%?

The king is around 23'000 Cd (around 7'666 lux for each XML) , from a 6xXML with "comparable reflector" I would expect double output and double lux.
Maybe more, considering hi class XML, high transparency glass, fine circuitery of X6... but to make 17'000 cd I need a Predator v1 (16'650 lux with 18650), flashlight with big, deep reflector, and small led die.

If I'm right and you cover with black cardboard 5 XML and you measure the lux/m of the light, you'll have a very different measure. That's because the max lux from 1 meter with many multi emitter lights is not a precise parameter.

There is actually another factor at play here. First off, the measures are not done at 1 meter - they are done at 10 meters, and extrapolated back. This is important (and required for ANSI FL-1 testing), because the beams of most lights do not fully converge at short distances. The 10m measurement is thus far more accurate.

But at that, I'm not sure if it is sufficient for all lights (i.e., multi-emitter and single-emitter). One issue that I have not addressed in my reviews is the background spill effect of measuring indoors. The ANSI FL-1 standards make no reference to correcting for background spill of the light (only for correcting for background ambient illumination, which I do). Nor do they specifiy the composition of the materials or wall colors in the testing environment. But because this testing is done indoors (where light reflects off various surfaces), reflections from the spill will artifically increase the centre-beam lux measures.

I have tried to measure this in my setup by blocking just the sensor, and reading the background spill illumination. Typically, for most lights, this appears to add ~3-5% to the overall center beam measurement. Not a huge effect, and one that tends to be consistent for a given class (i.e., heavy throwers - with dimmer spill - tend to be closer to ~3%, floodier lights closer to ~5%). As such - and given the ANSI FL-1 standards are mum on this issue - I do not adjust my measures for it. In other words, my numbers may be up to 5% inflated from the "true" centre beam throw - but it is likely the same for the "official" ANSI FL-1 measures as well. I have not specifically checked the X6 to see what effect its spill has, but I imagine it would be at the high-end (given its floody nature).

At the end of the day, the 10m ANSI FL-1 testing standard is a reasonable - but hardly perfect - way to compare center beam throw.

IMHO the lux/m measure of the multi emitter light is not "correct" since you "measure" 6 different spot (which is correct) AND all the light coming from 6 spills.

Yes, I would agree with this - but only in the sense that including the unavoidable combination of 6 spills is not going to be "correct" for great distances (i.e., they contribute to the center lux readings at <10 m distances, but are unlikely to contribute at higher distances). This is what I was alluding to when I said I am not so sure that standard beam intensity testing is so relevant for multi-emitter lights. Ideally, you would probably want to go to further out - but you would need to test this to see how far is actually necessary. And since that isn't really feasible, the 10m distance does still allow a standardized way to compare lights of similar class (with the caveat that care must be taken in comparing them to single emitter lights).

anche selfbuilt conferma

ricapitolando,
se ho ben capito, tutte le prove di SelfBuilt riguardo torce multi led ha sparato numeri a caso
