✌ FREEME - ASTROLUX MF05 SBT90.2 7000lm 3000m+ Thrower Searchlight - $390 (restocked) + Free Charger

Thank you :smiley: I’ve added my details to the list. And now we wait. I really want this light :sunglasses:

Thanks JasonWW.

Expect slower reply as i am facing problem accessing BLF for the past 2 days form my desktop.

Oh yeah
Are we there yet? Are we there yet?
Probably look like this next to the GT

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

That lens on the GT is 160mm OD with 150mm PCX lens

That silver head is 160mm?

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

Looks perfect for me. :+1:

Regards Xandre

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:

…me too…

Interested

Interested.

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.

I’m in if halfway affordable.

Its listed on banggood now,

That pricetag though :open_mouth:

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

Haha, yeah i know. I was reffering to BG:s pricetag :money_mouth_face:

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