well as you know i do have the 'big gun' in the works, just haven't gotten caught up yet to 'play'.. LK 14 will be regulated to 39V to pump 14,000L for about 17 minutes but in a 8" reflector so the 'punch' will be quite a bit more, not to mention the runtime..

this light is fantastic.. i'm working on a similar solution using 24 cells to overdrive the 64657 to 28.0V... i believe this light uses the 64655.. adding resistance from the ckt .. probably getting about 23.6V nominal to the lamp for 9410/6120 Lumen... (the lamp is underdriven about 3% due to ckt resistances)... could be a little more or less depending if the tailspring is fixed (35-40 miliohm is a normal maglite tailspring).

Great stuff though.. i remember a 'tester Mag250' a while ago from mac customs.. this is far more polished and yahoo.

I will be using the same host but black... likely to also use 2/3A but have enough extenders to use 4/5A so it's a possibility.. but with 28.8V source i can hold a constant 28V to the lamp.. the numbers work out like this:

28V to the osram 64657.. it's a '9000L' lamp vs 10,000 but it's rated for 300Hrs meaning... 'over drive!'... planning to push it to 27% overdrive to 320W.. that number is partially based on a logical amount of overhead for 28.8V battery pack.. but mostly based on the re-rating of bulb lumens: it takes 27.97V to achieve 15440/10030L

Thanks for the encouragement! now that i've seen it done.. time to do some tweaking!

What host are you thinking of using for the 24 2/3 A cells?

same host as 'mac' used.. the 'elephant'. it fits 4 across 18650.. so it won't even be 'tight' to fit 4 across of 17mm cells.. 6 x 4 cells means 28.4x6 = 170mm.. since i was originally going to use 16 (4x4x18650).. i think i can take off one of the 80mm extenders and have 10mm to spare! (bunch of that is from memory.. i still have to do measuring).

In any event.. i don't like the 75% dimming factor of unregulated lights so i won't have anything to do with them in general.. with the minor exception of the 'cake walk cheapo' of putting a C-KIU into a 2C and using a couple of AW's protected cells to run the 1111.. just plain stunning simplicity and 540L or so and maybe $60-80 to have one nice little hotwire light.

How many cells are in this ?  It looks like either 15 or 20 cells.  Where do you get the fatboy bodies to start with these?  Also, how do you figure out the higher Watt Osram bulbs to try out?  I see some others that are 250W and even 400W, but don't know what you guys look for.

Edit:  In no way are my comments about this light meant in any way to bait or antagonize EricMack, or Mac who made the truly magnificent light that is showing in this thread, and which I would greatly prefer having, but Mac is not making any more of them.  I only posted about this here and on CPF's for information if someone is looking for an alternative to perhaps have the same lumen output.  I'm posting this after having my comments misunderstood in the CPF thread, and again apologize for any offense that was taken to anyone.

================================================================


Well seeing there was no hope of ever getting one of these bad boys, I got Mad Maxabeam to make me a 3D version that according to JimmyM using AWR's re-rating Excel spreadsheet (God knows how he figured all these numbers out) out performs this 250W 24V light.  I named it "The DeathBlaster" and it is easily twice as bright as my 14.4V Torch 623's.  With a FM3H-2, it has a very dramatic center sharp hotspot that makes it very useable.   I have had it running for about a minute on/3 minutes off with run time still going after 4 minutes.  You can turn on this monster immediately hot off the charger which gives a battery pack 23.7V reading....with no flashing of the 64458 90W bulb.

It's not regulated, but MadMax said that the last hot drivers he tried using that AWR setup for these higher voltage lights all blew the HD.  I made a separate thread about this new toy.

never set up any hotdrivers for >19.5V for IRC lamps so not sure what you are talking about re: MadMax. I've not prescribed the use of hotdrivers for any use over the IRC voltage. (yet).

It took about 2 months to develop the hotrater.. the master database is even more wild... it has the runtime and 'c' rating for many different battery solutions.

Very cool to see some >100W lights out there be careful, IR will cause fires pretty quickly, it's a good plan to have the tailcap loose as a safety disconnect (if it still has anodized threads and actually disconnects).

MadMax (Ed) was finding that using the HD for the 14.4V Torch clone that he made with the 64623 bulb, that it would not hold up...something in the circuit would fry.  I guess he sent some back to you and just gave up on it being used for that purpose, so he gave one last one he had to me, and I'm using it in another 1166 12.7V setup with 2P4S of 14670...works great.

I did get one copy of a '623 hotdriver going, but the problem is that particular lamp just pulls way too much startup current. The '138 and the '625 are both far nicer lamps than the '623. right now the '623 is not a supported hotdriver solution but i can fix it, just don't have the time. The beauty of the higher power lamps.. FAR less current.. it'll be easier to make a 250W solution than the '623

I was trying to figure out the current in the 19.2v using the 64458, and blew the 10A fuse in my DMM.  Now I got this "Watt's Up" device that looks pretty cool.  Have to read how to use it properly, but it must have a shunt because it reads up to 100 Amps without needing any other DMM or devices.

over 10A constant means about a 30-40A spike at power on.. hence the blown fuse... not sure which lamp is the '64458'.. not listed in my osram catalog.

JimmyM found it....fabulous axial filament 90W bulb.  Osram 64458 link here.

nice score on the lamp.. i like axial lamps, i'll definitely have to try that one out..

the hotrater uses standard formulas that only really are meant for 20% and this is an overdrive of more than 100% so don't believe the numbers.. that said.. 180W or so, that part is probably pretty accurate and pushed that hard you can expect 35-38L/W or 6500/4200L.. which will smoke anything out there that can actually be used in more than 'spurts'.. (the 250W lamp will output more light). Even the '65W' IRC lamp pushed to 126W is probably topping out at about 3800L

It would be interesting to see them 64458 (at 19.2V) and the 250W compared side by side.  I think at some point, and especially with a MOP/Stippled reflector, the lumens are so overwhelming that it is hard to objectively tell the difference.

I'll tell you one recent development that gives a shocking result with all these Osram bulbs, FiveMega just released a 2.5 Deep mostly SMO reflector with 0.5" bore (with removeable cam to use with KIU), and I only tried it on one of my 6 Torches so far (some of them are the MaxBlaster using 15.6V with 64623 bulb)....but it gives an artifact-free incredible beam with a beautiful hotspot.  Just made the Torch infinitely more useable.
