Can you perhaps do a lux reading? Maybe do it @30sec (ANSI)?
The rooms I have are not long enough…
Doh!
40% below spec! What’s the process for getting a refund? Given the circumstances I certainly won’t be willing to pay the return shipping. Mine’s still on the ground in China, “at shipper’s warehouse” - maybe Dale can retrieve it before it leaves.
Before doing something like this I would expect others with the same result. From what I know there are others who ordered one and have a “real” Ullbricht device… even though I do not really expect big differences…
Actually I am the only one who has a GB and a retail version in hands to compare it.
“From what I know there are others who ordered one and have a “real” Ullbricht device”
Really? who/where? I have not heard of a single XHP35 that came close to spec.
You got me wrong - I also do not know a single 35 close to the spex.
But until today just a handfull of MT09R from the GB have been delivered…
In my Lumenbox I get with thrower LEDs mostly lower readings as with floodie LEDs.
Perhaps this could be an issue in your reading. But it does not explain that big difference. Did you had the luxmeter at the opposite “surface” to the Hotspot?
I am waiting for my MT09R and will share my measurement.
This is really dissapointing…im still waiting for mine, but at least its already in germany. Im gonna take a look at the beam pattern and the output compared to my current flashlight…but right now i dont think i can reach 1000m with 2500-3000 lumens less than advertised. Feeling a but fooled now and thinking about further steps.
I also think we should wait for further measurements, but if they dont go very well, we can at least see how good Haikelites new customer service is. :cry:
My problems start with flooders above 20.000 lm - with an X80 or an DX80 my values are not usable…
That’s why I said I would expect others…
My Luxmeter is aside the flashlight - so: yes.
This would be highly appreciated!
Anyone can sell me a complete light meter? I am talking about the one with the tube and so. I am serious about it.
Ok, I found the time to make the beamshots - the pictures are indicated:
The - from my point of view - important comparison:
The 1.200 lm more between Retail & GB are clearly visible - but the difference is still far too small. This to show the difference between 3.500 lm and 6.000 lm:
But for me another point of view is more important: even though the MT09R 35 fails completely regarding the 7.500 lm (or even 7.000 lm), the point with the 1.000 m of distance seems not completely out of range. Both Tiny Monsters are measured with more than 700 m - when I see the difference between the TM28 and the Groupbuy I would say that the full distance is not completely out of range.
Before somebody asks: as written I do not have enough distance in our home to measure the lux-values - ok, I tried it on location, but my luxmeter did not survive my major fine motoric availabilities… does anybody have a good luxmeter he would recommend?
From comparing the beamshots of the TM28 and the MT09R 35 HI group buy, the Haikelite appears to have better throw and to be slightly brighter overall, despite the calculations which show otherwise. Just my perception. Thank you for sharing your efforts with these lights.
A Gif might show it better:
With a surrounding like this it’s a little bit hard to show - it can be seen much easier on a wall (which I do not like to shoot :person_facepalming: )
As the “Lumen” are a definition of the total of the light sent out by the flashlight, it’s always hard to compare flashlights with different characteristics. While the TM26GT or the TM28 are more in the “Allrounder” area, the MT09R 35 is more something like an “Allrounder with good Throw”.
Thus said, you can see that the spot of the GB is clearly stronger - but the spil is smaller and darker. And this is where the GB (4.500 lm) looses the power against the TM28 (6.000 lm).
But while my TM28 is measured with a little bit more than 700 m of throw, the GB gives clearly more distance. As I said: from my point of view 900 m do not seem to be impossible…
… and think of that babe if it would have real 7.500 lm…
Well hopefully not all the lights in the GB fail to live up to the claimed output. My light is being processed through NY right now, so hopefully it’ll arrive sometime next week.
Any idea approximately how far away the gate is? And how far away the tree just visble behind the gate is?
Really appreciate your effort and time for sharing your results. Your beamshots are very useful. The GB 35 version seems a lot brighter than your retail version.
I have a few questions.
1) Do you test for lumens at startup or at 30s?
2) Have you compared your lumen results with other reviewers for the same flashlights? That way we can see if there’s a potential that your testing aparatus may result in consistently lower lumen readings.
3) You said the XHP70.2 GB unit had warmer tint than yours. What CCT is yours? If the GB unit you tested is the 4000k, unit then your 13.76 lumen result is the same as my estimate.
I just double checked my lux readings for comparison,
Olight H2R Nova NW 308 at startup (Several reviews put this at about 2,360+ lumens at 30s)
Acebeam H15 NW 324 at startup
Astrolux MF01 219c 1,220 at startup (known to putout 9-10k lumens)
Manker MK34 219c 4000k 560 at startup (measured 4,914 lumens in Advanced Knife Bro’s youtube review)
Emisar D4 XPL v2 HI 4000k 420 at startup (known to produce 3,800-4,000 lumens)
MT09R XHP70.2 5000k 2,170 at startup
MT09R XHP70.2 4000k 1,640 at startup
From my data, the the XHP70.2 500k version should produce around 17k lumens and the 4000k version should produce 13k lumens.
Thank you for the update :+1:
The results are disappointing, but not unexpected. It’s going to be interesting to see some more measurements when more of the groupbuy lights arrive, but I expect they will be more or less the same.
Thank you for taking the time to do this.
Thank you!
That’s why we are here.
The lumens have been tested at startup - but based on Post #929 the decrease is continuously, so the difference between 0s and 30s can be neglected…
Actually it seems like I am the first one who tested a GB-version. My test of the retail-version is very similar to another one sold in Germany and also near to the values Terry measured for the prototype.
Regarding my general measurements I compared it inside the TLF and they are in general in the area of others - so it seems to be on the same level. Also the values I receive for other flashlights are on the level of what others measure with there Ullbricht sphere. My Luxmeter seemed to work quite well - another point why I am actually quite upset…
Actually they only have CW in retail - the CCT of the GB-version is not indicated. But especially for you I murdered my strict “no wall-shots”-policy:
From my point of view the GB must be the one with 5.000 K
As written above, the GB70 I have in hands seems to be the 5.000K - and as written it gives a good 6% more power than my 6.000 K. But from my point of view 17 klm are far away - see the comparison with the DT70
Another point discussed was the difference between the GB35 (4.500 lm) and the TM28 (6.000 lm). From my point of view, it can be explained best with the wallshot (again!). While the MT09R35 give its power to the Spot, the TM28 has a bigger and more powerfull Spill, together with a bigger Spot:
… its hard to show it with a photo…
Im anxious to get some actual lumen tests of the cool white version of xhp35… i really hope it not just max 5000 lumens that would really be a dissapointment…
