    Default LuxLuthor's Most Powerful Maglite Mods List

    This is my personal ranking, which I update from time to time. These do not yet include the Osram IRC 50W & 65W and other bulbs. I moved my post out of this topic location which was getting a bit long.

    Please note: Based upon my destructive bulb testing, these Lumen claims are using an outdated, innacurate AWR spreadsheet that does not reflect real, verified lumen numbers...so at best use these rankings as relative comparisons to each other. In other words, if I say the "MaxBlaster" puts out 4400 (bulb) Lumens, that is not turning out to be a "real" lumen number. It is a case of everyone agreeing upon the spreadsheet predictive values, akin to the "Emporor Has No Clothes" fable.


    • 1)Sylathnie's Sublimator Osram 64663 36V 400W with 10s Emoli 18650 cells in Elephant-II with FM 2.5" Turbo Head.








    • 4) LuxLuthor's HyperBlaster. This uses FiveMega's Chrome Elephant with extender body, and holds 3 stacks of the new Elite 1700mAh AA cells welded into a single pack. 10A side switch replaces stock Mag switch. Overdriving the Osram 250W 64655 bulb. 21 cells of Elite's new AA raw power....Oh yeah. It's bright.


    • 5) Mac's 250w Elephant using 20 x 2/3A Elite NiMH Osram 24v 250w 64655 bulb at 10K L (?)


    • 6) Osram 150W 64633 at 16.8V (ideally with new AlanB/JimmyM regulator). I just added this based solely upon my destructive testing, but have not made a working light with this due to the 50 Hr rated bulb life, and high liklihood of flashing the bulb with most battery combinations. If you can set a regulator to 16.8V, it should fit into this ranking.








    • 10) Ginseng's Legendary and beautiful Aurora/Aurora 2. One of the most beautifully made lights I have seen, made by one of the "Grandfather's of CPF" (I put Newbie, js, bwaites and a few others in that rarified category). Reading his post reminds us of how much love and attention can be put into projects like this. He even worked on the finish by buffing and had wet-sanding before having it nickel plated. This was made way back in 2003 using the 64623 & GP2000 4/5A cells, and a 10A rocker switch. It screams "custom made" but looks better than 95% of any lights out today. Likely puts out the same as Mac's Torch.


    • 11) The USL mod (search for it), and Mad MaxaBeam's Maglite like above MaxBlaster that uses a 13.2V battery pack with the Osram 64625 or 62138 100W bulbs. It is a whiter, and cleaner bulb than the 64623, but not as bright, not as hot, and not able to be driven with the higher voltage.


    • 12) The 64430 35W 6V bulb overdriven to 9.8 or 9.9V gives about 1800 bulb lumens. Best to have a regulated drive with soft starting. Wonderful solution to a smaller light. Because it needs about 9.5 to 10A of current you should look at powering this with either the new A123 or Emoli safe Lithium chemistries, or a NiMH high output pack using cells such as the Elite 2/3A or 1700mAh AA's. I have a large supply of the authentic Osram 64430 bulbs that are no longer made.




    • 14) The legendary Philips 5761 30W 6V bulb overdriven to about 7.2V Many have used this bulb in C size Mags with 2 x AW C Li-Ion cells, but it requires about 5.5A, so it is close to tripping his protection circuit. Again ideal for a regulated driver with soft start. The Emoli 26700 or 18650 are alternate battery sources. Works out to about 1400+ lumens.










    • 19) ROP using a potted Pelican 3854-H which is a 24W bulb (larger one that has pointed tip), powered by 2 x AW C Li-Ions in a 2C. Just tested this with freshly charged Li-Ions that measured 8.2V in bulb socket. No resistance fixes done. I did attach a lead to the tailcap spring and making contact with side gave me 4.1A. Recent 3853-H was also tested in Destructive thread.

    A bump for this very useful thread - good to have all the info here, away from the other thread.

    You show in your list:
    • Host configuration
    • Bulb type
    • Power pack type
    • Vbatt
    • Lumens (bulb & torch)
    It would also be useful to show the current draw of these individual bulbs, to save people having to look this info up elsewhere or work it out with the hotrater etc.
    Resistance is futile...

    Yeah, I agree.

    I am supposed to get the Mastech HY3020-D late this week, and I'm thinking of using AW's new D (unregulated) Driver as a platform (out of the Maglite--to try and give a standard bulb holder that people can compare to) which will tell me at a particular voltage exactly how many amps the bulb is drawing....so "weak" batteries or various resistance of mixed Maglite setups will not be an issue.

    The problem with AWR's Hotrater is for the most part he uses the formulas that were taken from the WA website, with a little adjustment for various Ohm assumptions.

    My goal is to test the bulbs at what is supposed to be the ideal Voltage (this Mastech will supply however many Amps the bulb wants, and with its soft starter I should be able to get some useful real world readings. This is also important for specifying Voltages to set up once AW comes out with his REGULATED D Driver, for a given bulb.

    Once I see how the bulb looks at the AWR Hotrater "Ideal" voltage, I am thinking of slowly climbing up the voltage until bulb flashes...which will be useful information. I may have my Meterman light meter in play at a fixed distance to get some objective comparison between bulbs in some sort of bounce reading.

    That will be EXTREMELY useful info to add here. Lol I'm hopeless with the hotrater - it usually throws up weird results when I try to enter anything new.

    I have found Mdocod's formulas very useful too.

    EDIT: The hotwire info in this old thread needs updating too, although it might better just to incorporate the results here.

    Just wondering, would I have better luck with some ROP bulbs or WA 1111s in a 2C mag with 2 18650s in them? Output and runtime wise, because I don't really know the voltages on AWs protected cells.

    Thanks for the fine compilation of totally useful information, Lux !

    I'm patiently waiting for AW's regulated switch for C hosts to see what the 5761 run time will be on 3 of his cells. What voltage setting would you suggest as a happy medium of bright and fair bulb life ?

    Thanks again for your hard work that we all benefit from.

    Another good Maglite mods thread. An interesting list. What would be really good would be one or two of those links leading to a lists of components and where to get them, and if they're still available.
    I think I've been searching and reading for...well, I'm suffering from lack of sleep, so I don't really know, but it's about 10-14 days, and I still haven't got one organized.

    I was trying to figure out some version of QuickBeam's light box, but the wax coated milk carton won't cut it for these torch lights. (I mean "torch" in the American lexicon, since much of the world calls flashlights "torches.")

    Default Re: LuxLuthor's Most Powerful Maglite Mods List

    I am going to try and find what I consider "the sweet spot" for a bulb which I believe means a life of 10-20 hrs. I want to clearly establish the flash point of various bulbs, so that is no longer a mystery, nor have it be related to initial spike current, from some level of overcharged batteries, or from a variable series of resistance setups, NTC, etc.

    I'm also planning on using the temp probe which came with my Fluke 179 to see actual temps inside of a FiveMega enclosed aluminum head with Borofloat lens. It tests up to 750° F, so I may need to drill a hole just large enough for the probe in a head to get accurate sampling. This would also allow me to see how much a layer of FiberFrax would insulate the KIU, wires, and hotdriver below the bulb.

    I recognize this will likely involve sacrificing 3-4 bulbs of any particular bulb to get some accurate data points, and may subject AW's 4-D to more heat/current stress than he anticipates. To minimize that, I will start out with the lower 6V and WA bulbs before considering moving to the 50W and higher bulbs.

    I'm thinking it would be good to do the run times in 30 - 120 min segments which would be a more realistic representation of how these bulbs would be used. Not to mention the fact that I am not going to want to sit, transfixed on a bulb and readings for 20 hours straight.

    I want to try and standardize and control as many aspects as I can think of when setting this up, so it could be used in conjunction with AWR's Hotrater spreadsheet....perhaps leading to some adjustments, and ultimately becoming a reliable bulb reference, similar to the excellent work SilverFox has done with the battery run time curves.

    Awesome, I love your summary.

    I have been away for 18 months, so it's hard to catch up. Glad to see my ROP made the ranking at all. Thought it would have been too wimpy as you guys pushed the frontier back for all light-kind

    Not intending to compete for ranking position, but just to confirm - the six-SubC NiMH ROPs using Sanyo 3600 high-rate SCs is much brighter than the ROP on lithium. Eyeballing it shows a significant loss in output. Of course the ROP/LE is a much smaller 2C light compared to the 4D monster with the SC's. Instaflash risk is very real with the SCs, whereas the Li configuration seems to have virtually no instaflash risk due to significant voltage sag. My original ROPs have no resistance fixes or anything special. I've got a 4D/6xSC and 2C/2x18650 of my own.

    4.1 amp is around there. I've taken measurements around the 4.15A mark too, close enough.

    I'm considering building something in the 1.5K lumen range. What would you guys recommend? Planning to use A123 cells, soft start driver and preferably a very easy to obtain bulb. I hate my lights being disabled because of popped bulbs.

    BxStylez, I just did reply to your PM. I was kind of hanging back because I wanted to test these for optimum voltage, and see what the Osram is actually doing.

    Kevin, I'm sure higher voltage/amp NiMH cells would push the ROP higher....so it was definitely a great discovery for its simplicity.

    I have yet to add the Osram IRC (Infrared Reflective Coating) bulbs, so I'll revise this list and what I think the best regulated voltage (& amps needed) for a number of lights.

    Hi Lux

    Some thoughts on Light Metering ? and no cheap/expensive integrating spheres ?

    Firstly some of the Light Meters generally available

    CEM DT-1309 with Backlight + USB graphing to boot.

    CEM DT-1308 and here Backlight but no USB but cheaper and more like it for me.

    Meterman LM631 / Tecpel 531 Lightmeter With Backlight (Google it for prices)

    My idea is that these and even the cheaper Chinese ones with no backlight LX1010B or DT1301 greater range could all be used to give fairly consistent readings for comparison purposes.

    First Incan Bulb-Lumens - Take off the Torch head to reveal the naked bulb in Candle Mode - measure Lux at say 1metre - right angles to filament - horizontal separation (same level) same for axial filament lamps just avoid the return wire if external, although it probably won't change anything much.

    The filament acts a point source so the Lux meter reading is just a small part of the total 1m sphere surface

    Lux level should be proportionate (?) to Bulb Lumens so take a known trusted value like the ones for the WA1185 from the WA re-rater page at a set Voltage or two and check the ratios - that is the first interesting experiment. Should be a simple ratio between Bulb Lumens and Lux at 1m ( I think )
    Might have to check how much the room, if not a Black-Box room contributes to the Lux value or experiment outdoors at night - but not as easy to use a constant Voltage supply outdoors !

    Another value of Lux could be taken for all bulbs at 1m (or suitable distance) for Centre Spot value from say 3" FM MOP or other semi standardisable reflector of choice ( or lots of mirrors and heads ! ! ! ) using standard/optimum Voltages.

    This method should be fairly standardised and repeatable by other members ? ? ?

    I'm going to post these thoughts in the LuxLuthor Most Powerful Thread to see what everyone thinks and they can point out the glaring errors

    Let me know . . .

    Cheers Pete

    Pete, thanks for your information. I bought the Meterman LM631 a while back, so I'll use that one. I can position the Meterman at a distance of 1 meter, and enclose the sensor head inside a 15 inch black tube sealed around it to eliminate reflected light. With the tube horizontal to the table, and so the attached sensor is the same height as the bulb, I can line it up so it is aiming at the side of the bulb. I'll check first with brighter bulb like 64458 to see if that maxes out the meter, and move it back farther if it does.

    Figuring out the head size and zoom will be a more variable issue....but it would be interesting to see how a particular voltage/amps/lux @ 1m translates to a farther distance spot from various Mag head beams.

    Pete, using the 12" black tube with 1" I.D., and a thin layer of black foam at meter end to seal sensor in end works great. LOL....I cannibalized an old vacuum cleaner extension tube, and abraded the inside so there was a diffuse pattern coming through other end, as previously the shiny inside surface reflected artifacts.

    Only thing is my preliminary "spot" readings at 1 meter of 64623 with a charged 14.4V pack (not the power supply yet) only gave about 450 Lux. The FM special Carley 43W in a 2p4s x 14670 (stock mag parts), only gave about 150 Lux.

    Seeing that this LM631 scale can go up to 20,000 Lux, I think I should put it closer than a meter. To see the effect of the tube, holding the sensor outside of the tube with Carley only bumped it up to about 170 Lux.

    I'm thinking I should find a distance where the 64458 at about 22V gives a reading of about 10,000 Lux, unless I get way too close. Maybe 0.5 meter? That will still leave Lux room on the meter for measuring 250W setups. It seems the most useful thing is to get a relative proportional, but objectively controlled setup...which we can then compare to the Hotrater spreadsheet, bulb manufacturer BL ratings at a specific voltage, etc.

    I was talking with AWR, and also think it may be best to do most of the "light point" testing in just a plain KIU bipin holder which is how he did some of his tests...and then see how volt/amp/lux compares at a couple points when the new AW D Driver is used (still waiting on mine).

    Lux,

    When establishing these numbers how long are you going to test a bulb at a given voltage? The reason I ask is that at one time I was convinced that you could run the ROP with 7 nimh cells and do just fine. What I ended up finding out is that after around 15 minutes of constant on time is bubl explosion. I have had this happen three times. The first time I thought it was maybe just a bad bulb. After the second time I was curious. After the third time, I was smart enough not to try it again. These bulbs completely shredded a nice reflector and chipped the inside of a UCL lense when they exploded so things were really moving when it came apart.

    Nick, you should see the "burial ground" of dead bulbs I have now. Amazingly, none of them have exploded, but I faithfully wear my Mr. Wizard goggles when doing the tests in this thread.

    I start with the projected life that was taken from AWR's Hotrater spreadsheet to target a life of 10-15 hrs. Some bulbs are pretty close to what I have on those spreadsheets as "pending" on far right, others have little correlation.

    Remember with my test platforms, I have virtually no resistance to blunt the voltage we use with various battery combinations that varies in the Mag setup. Remember that a fully charged NiMH cell will have a voltage of 1.4V, so your 7 x 1.4V=9.8V

    Then, depending on what parts you are using, resistance fixes, etc., you need to take that into account in your setup, as more resistance of a stock mag will decrease the current delivered to the bulb at a given battery voltage.

    Lux,

    I am well aware that the voltage is actually a bit higher. I was just quoting the nominal voltage of the pack. As far as resistance fixes, I have the mag switch fixes done but I have not done the tail spring fix done as when I built that particular light I had not seen a post about that being a problem. These lights popped around 2 or three years ago when I first got into mag hotwires.

    My main point of bringing it up was simply to find out if you were just testing the bulbs for their highest possible voltage so we can use a hotdriver and get the most from our lights. I wanted to be sure that the tests were running for a decent amount of time before the information is stated as good to go. As I said, each of three of my bulbs failed at around 15 minutes of constant run time. What happened was first a slight dimming followed by a spectacular show of colors that ended with a poof. Each time, the bulb completely failed and shredded a reflector. After the first one happened I tried again in the same damaged reflector as at the time I didnt have a spare and I was using the light for photography. The third time was simply to see if I could repeat the results and it happened again. That was when I decided that I would no longer use that setup.

    As a general note, each time the bulb failed the light was sitting on the tail cap pointing at the ceiling to bounce light back down on what I was photographing. I dont think this would have any bearing on the bulb failing but thought it was worth mentioning.

    Don't take the first sentance the wrong way. I am not in any way insulting you or your intelligence. I admire the work you are doing for the better of the community. I have a great respect for that. I am just interested to find out if the same thing could happen at different voltages. Voltages higher than a nominal 7.2 but lower than nominal 8.4 might result in similar results in the same amount of time or a bit longer.

    Thanks again for the work you are putting into the bulb tests. This will come in real handy when we have a hotdriver setup. .

    Nick, I just took readings and moved up to next reported voltage step. I didn't pause, as I did not want to put additional run time stresses as the voltage increased. The first stage was to detect the Lux, Amps, & heat at various voltage levels, as well as determine the REAL flash point with minimal run time having stressed out the bulb first.

    Then next stage which I have been slowly doing is to run a bulb at what should be an ideal voltage using the Hotrater target of 10-15 hrs. I do the runs at a set voltage in stage two in various segments of 30 mins to 2 hrs. I have been checking to see how much the Lux drops off with run time, and the test is done when the bulb burns out at that fixed "ideal" voltage, or when the Lux drops so low the bulb might as well be dead. There is no other way to do the tests with any decent run time, other than to pick 1 or 2 estimated ideal voltages and see what happens. Suffice it to say that the drop off in Lux with some bulbs is shocking, as well as there not being ideal correlation with various bulbs to the Hotrater estimated run time at various voltages.

    So the bottom line is you were running too much voltage (with the resistance fixes) for that bulb. There are many setups where the resistance fixes should NOT be done because you push the bulb too close to its flash point. I was not doing ideal voltage run time/Lux predictions with the ROP, since I only had the one bulb.

    I'm saddened to see that the Aurora and Aurora2 are not on your list. The Aurora debuted in the winter of 2003 and was the first of the truly "super" Maglight mods. Beyond just bulb and battery upgrades, it rebuilt the concept of an incandescent hotwire from the ground up. I acknowledge the improvements in sophistication and power of the generations that came after, but wherever I am now, I would rest more peacefully knowing that these lights and the inspiration they fostered were not forgotten.
