Probably look like this next to the GT


Close, except MF05 has a 25mm wider head than GT.

That silver head is 160mm?

It looks a little smaller in the picture. Okay, I guess that IS what it will look like. Lol

I adapted that lens to the GT for a size comparison before I knew what size it was going to be. Cant wait to get my hands on one Innocent

Big, heavy and now you’re telling me it has a huge price tag! They might aswell put 4 SBT90.2s in it at that weight. I maybe be wrong but I don’t think this light will sell very well. Another company will just come out with a smaller and lighter one with the same or better throw. Acebeam K75 weighs only 844g so 3.4Kg is four times as much! I was debating whether I should get this or not and now I know the answer.

…me too…

Something don’t add up or it just seems rather average. 3.15km from 2.7km for its monster size? Thats it, only marginal? imo 3.5km minimum or whats the point? I think they didn’t make the reflector well or something. Any 1-2min Turbo mode to near 4km? That would sweeten the deal.

LED got along way to go in throw…

Ok, basic lessons - refer to the flashlight wiki here: https://flashlightwiki.com/Light_Output_Measurements

Candela (kcd) varies proportionally with lumens. I prefer using kcd to compare, rather than distance because I can directly relate it to lumens. For example, you make some tweaks to improve amps to the LED, resulting in a 25% boost in lumens. You should expect to see a 25% boost in candela -- straight proportional.

Distance is calculate by:

    dist = SQRT (candela * 4)

This results in a smaller percent increase in distance (meters) than you see in candela. It's kind of like lumens - doubling the lumens does not double the perceived brightness your eyes see. So we use lumens to compare total light output, not some unit the eyes can perceive, that's why we should use candela and not distance.

 

Example: 150 kcd doubled is 300 kcd. 150 kcd is 775 meters, 300 kcd 1095 meters. So from 775 to 1095 is not that significant - is it worth it then to double the candela? The MF05 is not double the head width of the GT90 so I wouldn't expect it to double the candela, it's a bump, a fraction, and that's what you are seeing.

 

So you think a jump from 2.7 km to 3.15 km is not enough? Ok, than stay with 2.7 km knowing that light could never be made to exceed 3 km with the same LED. I think the proportional increase is about right for the proportional increase in reflector width.

Distance spec values to me are kind of meaningless. On that page I referenced in the flashlight wiki it states throw distance is based on 1/4 lux, which is a pretty useless level. MythBusters determined you need 4 lux to navigate a room if your eye aren't adjusted to the darkness. To me, I would like to see at least 2 lux on a distant object to be able to see it somewhat clearly.

Doing the math, if you get 1/4 lux for a 150 kcd light at 775 meters, to get 2 lux, it's 278 meters. - big difference. It's all about the math, what you find as acceptable, and of course trade-offs for carry vs. throw.

The GT is 35% wider than the TN42 and has nearly double the candlela. GT mini is half the size of the TN42 and has a bit under half the throw. Seems like double the head width should get you double the throw but to get double the candlela you only need a 40-45% increase in size. With smaller lights the difference will obviously be more due to the bezels.

First time seeing a retail price? It will be cheaper. Under $400 according to Freeme for the group buy.

Hopefully it’s a LOT cheaper than the BG listed price of 785.24 CDN. I would like one but not at that price

Instructions arriving via private message? How to purchase?

Is there a simple way of simply easily buying, instead of struggling to negotiate the Byzantine rube goldbergesque method of purchasing?

Because I like big lights, my flashlightical views lean heavily toward both the extreme bright and the extreme heft.

Oops, BG rep just went offline 5 mins ago. He did tell me that Samsung 30Q is still the recommended cell for such setup. For the past MF04 series, both button top and flat top cells are supported.

 

MF04 extension tube for reference.

 

As for the grip, product page image shows unprotected Samsung 48G 21700.

Only 60pcs for first batch selling at zero profit margin.

Price will increase for subsequent batches (if they are still making wink).

I’m a distributor for Mateminco so if these actually perform to spec I might import some to sell. Lucky US customers at $399, it’s over $700 in NZD incl 15% tax. It’s a beast of a light though, pretty tempted to get one for myself

Are all 60 accounted for already? If not, do you know how many slots remain?
