The most thorough all in one place teardown is Lexel’s Review I’ve not seen too much else on here, but there seemed to be some stuff going on over at the German site. Someone fixed the uneven brightness levels during low by swapping in a TA driver with narsil and there’s a demo video of the light ramping.
Also I don’t think it started since I’ve had it, just never noticed, but in the lowest mode I can see that one bank is ever so slightly brighter than the others. Once the light has warmed up they all seem to even out. I did not shine the light into my eyes or anything, just ran it on turbo outside of my vision until I felt heat then went back to low and they were even.
And JasonWW:
The Xp-G3s can easily do 1000+ lumens each as long as the current is there to be supplied. The light would be pulling 60+ amps, but with 4x 20amp high discharge cells that can be supplied to get this thing cooking at 20,000 lumens
Maybe both? Unsure of “exactly” what you are asking. It’s more of a mod if anything since the uneven LED lighting is only a slight issue in the lowest mode where it matters the least. I am really considering doing a driver swap, but I really like the constant current drivers in it. The Q8 has me in love with Narsil though… and this would be a fun light with ramping.
Thanks, I had another look at Lexel’s review, I forgot how thorough he was in showing everything
About the output: The MF-01 can be seen as 4x D4’s in tandem but with 2 more leds and the big copper board, the output could be a bit better even. So 16.000 lumen from the XP-G3 version should not even need minimising every resistance in the path. It does require low resistance springs in the carrier. If Astrolux goes really fancy they can even make a new ledboard and use Luxeon V leds, in which case 20K lumen is met.
Yeah, my bad. For some reason I was thinking 700 lumen was about their limit. I looked up djozz’s test and see they can do 1800 lumen at 8 amps! That’s crazy high.
Your forgetting it’s a 2S2P carrier. You’d need about 30 amps at 8v to get 20,000 lumen. It’s the same 15 amps per cell, though. Sounds doable, but eventually you get such low run times that you need to step up to 8 cells.
Plus the components needed for those high amps may cost a lot more. They might need 6 of the little drivers instead of 3.
I wonder what Lexels Tx Avenger FET driver can do with good cells?
The next logical step would be to add active cooling, so a higher output can be maintained over time.
OR
Go with a ridiculous number of LED:s (like Vinh’s Solis) to take advantage of LED:s being more efficient at lower currents (and thus running cooler).
” We are sorry for the inconvenience.For the problem please make sure that all the batteries are fully charged and with the same power.And then make sure the body tube and head are tightly closed.Also you can try to stretch the spring on the battery carrier for the good connection.At last please check if the pill on the battery carrier is tightly too.”
I’m starting to get the runaround from BG’s customer service. Should I be contacting someone else, instead?
Okay, your guy who’s light went turbo on one bank when power was connected. I had to look it up because I can’t remember.
Do you want to take the light apart and look around, wiggle some wires? I was thinking one of the 3 drivers had a short to ground. Just taking the driver out and poking around might fix it. If not, then it’s definetly a warranty issue. Make a video for them. It’s not a battery carrier issue.
first i will give banngood a bell cos the second one looks like its about to fly off ifthey sen me a new one then i will have a crack a soldering if i stuff it up well atleast i have a spare battery carrier ?
