Which one would you recommend? Niwalker MF5SV1 vs BLF Q8

BlueSwordM · 2019-03-13T20:56:41.000Z

I mean, they are driving the emitter 10% harder at 2200 lumens, and said they got much better focus out of the reflector.

I’m cautious. If it’s better than the BK-FA30S, it’s all good.

Otherwise, something seems off.

mattadores · 2019-03-13T21:44:28.000Z

I dug everything up I could to try and estimate:

	lumen claimed	lumen tested	candela claimed	candela tested	throw claimed	throw tested
BK-FA30S	2200	2199	650 000	563 000	1600m	1501m
LR7SV1	2650		903 500		1900m
LB11SV2	2650		903 500		1900m
MF5SV1	10 000	9 350	440 000	61 000	850m	494m
MM18JR	15 000		440 000		850m

so based on Maukkas reviews their lumen outputs appear to be bang on. to jump from 2200 in the BK-FA30S to 2600 in the two new ones is a 20.1% increase in output so it definitely looks like it's possible to achieve the additional throw.

Unfortunately the MM18JR didn't even come close to the throw specs but if they're indeed driving the leds 50% harder up to 15 000 lumens maybe they finally achieved the previous throw specs which were way over actual spec or they're only driving the 70.2s 50%+ harder to achieve the lumens and will have similar dismal throw specs lol I can't decide if I need them or if I should just save my pennies for the eventual MF03 or MF05 or GT4...

Tom_E · 2019-04-01T14:42:12.000Z

Think you got the last 2 lines there reversed. Maukka reviewed the older MM18JR model. I'll be getting an MF5SV1 in, shipped, maybe a few days away, and I'll test and post.

For the lumens, I suppose they cranked up the amps in this new model - it's certainly possible to get 15K out of 2 XHP70.2's and a XHP35 HI, figure 6.5K each, then 2K more for the XHP35 HI...

I would expect the throw #'s to be about the same as what maukka got. What were they think'n??

Dimensions seem to be the same so I would think throw is unaffected if the reflectors stayed the same, maybe they got more amps goin on hte XHP35 HI but that wouldn't make much difference.

BlueSwordM · 2019-04-01T15:06:44.000Z

Niwalker said they got the focus better with the new reflectors.

That means the reflectors have been tweaked a bit to achieve the optimal distance to focal-point.

That means either a different centering ring or a tweaked reflector as mentioned above.

Tom_E · 2019-04-01T15:12:31.000Z

Yeah but 61 kcd to 440 kcd? Or 494 m to 850 m? No way in something this size.

BlueSwordM · 2019-04-01T15:22:30.000Z

Of course.

Do they do any kind of.spell checking.on their.pages?

That was exactly why I ended up passing on this light. I love the idea of a selectable throw/flood combo light but this isn’t really a good throw light.

I have a handful of flooders/mild throwers that make 10 000+ lumens already so when this light can’t throw even as far as the BLF GT mini I don’t really consider it the best of both worlds. More like a great flooder with a focused beam that can throw a tiny bit

Tom_E · 2019-04-01T15:39:41.000Z

Dunno how they can get candela and distance messed up, plus it's consistenly wrong in several places... ugh......

I left a message on their site to correct the specs on these lights. I'll see if they respond.

This is a bazaar light. With 3 separate buttons, you would think each would have it's own turbo, but that's not what maukka found. If they did have separate turbo, would be interesting to see how the 2 XHP70.2's compare to the XHP35 HI in throw - betta not much advantage to the HI. Think it's more about choosing what beam pattern you want. If they did it better, they would have made the reflector for the HI bigger than the others, at least.

lol incoming correction:

MF5SV1
lumens: 15 000
throw: really far

Tom_E · 2019-04-06T15:27:27.000Z

The light arrived yesterday. I'm a bit under the weather and not up to doing much with it, but it's an impressive light, rock solid, 700g is certainly something significant in your hand.

Only way to get to max/turbo is thru momentary mode, but that's easy to get to - simply press&hold the button of choice. 3 buttons - 1 for the dual XHP70.2's, 1 for the XHP35 HI, and the 3rd button for both. The 70 reflectors are shallow and a heavy OP, and the XHP35 HI reflector is SMO and deep. The depth keeps the flood width small. The throw reflector though is just too small to get significant throw #'s from it. The XHP35 HI by itself really doesn't have much distance, but with all the LED's ON, it does much better, but still I would say in the range maukka tested.

BlueSwordM · 2019-04-06T15:30:16.000Z

Wow that’s even heavier than the MT03, and MT09R.

CM2010 · 2019-04-06T16:17:31.000Z

I should get mine sometime in the next few days as it’s just made it to the uk.

CM2010 · 2019-04-08T09:56:17.000Z

Got my MF5SV1 today, not sure why they only have it as 4000lm as the highest unless you are in turbo?

Tom_E · 2019-04-08T13:28:14.000Z

BlueSwordM:

Ooops, my bad - that was from the website. The website has typos, copy/paste errors, and outright plain wrong stuff.

The manual is somewhat better, it says 490 g and I measured 486 g, compared to the Q8 measured at 403 g, all without batteries.

The head comes in at 319 g, compared to the Q8 head at 260 g, so pretty much all the extra weight comes from the head.

CM2010- mine came with no box, but the pouch it came in is really nice. Also are the two top buttons reversed from how the manual says? On mine, the XHP35HI is the right top button.

mattadores · 2019-04-08T15:53:31.000Z

Thanks for the updates! Sounds like it’s a nice bump in lumens but the throw side of it remains the same.

Can’t wait to see some measurements or pictures of beamshots

CM2010 · 2019-04-08T16:18:05.000Z

It came in a paper thin cardboard box which was next to useless and yeah the buttons in the manual are back to front.

No - the lumens are the same. Manual says 15K for all LED's, 13K for just the 2 70's. I measured about 9K for all, 7K for just the 2 70's. I measured lower than maukka did, but used fresh 35E's, not 30Q's. I'll re-measure with 30Q's to see if I get closer to what maukka measured on the older model. Might be a little bump but not much, if at all.

Ok - mine did come in a heavy duty shipping box (DHL), but no Niwalker box.

CM2010 · 2019-04-08T17:26:44.000Z

It wasn’t an official box, maybe just any box they had at hand.

Soooooo lol it’s no different than the MM18JR

ooh man

Tom_E · 2019-04-08T21:35:37.000Z

As I suspected, the 30Q's did marginally better, so about the same as maukka's testing of the MM18JR.

I dunno - I don't think I've seen such a blatant disregard for published numbers with a somewhat higher quality brand name. The throw and dimensions seem to be a copy/paste error from one of their big throwers (correct dims, still bad throw #'s in the manual), and the mentioning of 15,000 lumens is in the manual and website, seems to be purely made up. I don't get it...
