WA 1331 instaboom!
1331 is hands-down the most fragile lamp i've used.. it works fantastically well when regulated and is extremely efficient. I pretty much 'gave up' on unregulated lights.. they drove me nuts. the 1331 lamp is a 9.6V lamp, not 10.8 nor 11.6 (like the 1166 that FM uses in the '700L').. 1111...- andrewwynn

explosion when charging li-ion cell, Universal Smart charger set on wrong voltage
never said they will self balance.. i also said it's important to make sure cells are relatively balanced, what i did say.. was there is no 'high risk' in the one example shown and enumerated above... there just isn't.. the 'high risk' packs which people are showing examples of are 50 to 100WH+...- andrewwynn

explosion when charging li-ion cell, Universal Smart charger set on wrong voltage
The 'adding of voltage' does not really work that way Tom, you should know that of anybody.. charge that pack up fully and the cells will get closer in voltage absolutely guaranteed unless one fails short or something. Not likely to happen from a pack that is already clearly mostly charged...- andrewwynn

explosion when charging li-ion cell, Universal Smart charger set on wrong voltage
lux lux lux.. you are an avid flashaholic with a collection worth more than many people's cars, it's tough to believe you didn't do the research about LION batteries when you are very very thorough about how you go about buying lights and such. It's simply amazing that you didn't stumble into...- andrewwynn

explosion when charging li-ion cell, Universal Smart charger set on wrong voltage
charging an M6-R pack is no safer than charging an HDM6 pack. It's hogwash to say an M6R is 'much safer'.. yeah if you shoot a bullet through it maybe... there is no basis in fact with that statement, just another unsupported jab against me. I just posted exactly what i see from this example...- andrewwynn

It's an important and valuable point to make regarding the critical nature of matching # of LION cells to the charger setting that is very true.. this.. as all other LION 'nasty events' of which i'm aware is a case of operator error not of the charger or the cell which did exactly as they were...- andrewwynn

The "M85".. 2D hosted Mag85 1360/880L
there is SOME improvement in saftey when using individual cells.. about as much odds in helping as there are in being a liability (there is a very interesting thread about a 'protected lion' that shorted out internally from pressure in a battery pack... overcharging has to do with your...- andrewwynn

Magcharger bulb on 2 18650, how many lumens?
lol.. did you actually use a calculator? the torch lumen conversion is in the big orange bar! with bulb life rated to 3.5hr means you can expect about a dozen uses out of the lamp so yea that's a big problem. you want numbers at least 6 hours and 10 is better.. when direct-driving if the hour...- andrewwynn

Magcharger bulb on 2 18650, how many lumens?
re-working with the fixes described.. you should have about 40 total miliohms resistance.. (down from about 200!) that will net you about 7.14V to the lamp and about 264L out the front.. your 250 was ammmazingly close! The lamp does re-rate to the 'danger zone' of 6.2hrs lamp life.. don't use...- andrewwynn

Magcharger bulb on 2 18650, how many lumens?
using the [http://hotrater.rouse.com]hotrater[/url] you can put in some estimated values.. i used 8W, 1.34A and 6V for the baseline.. i put in 180 miliohms resistnace (assuming you didn't put in any resistance fixes).. I put in 200L because i read once that mag states the lamp produces 200L and...- andrewwynn

The "M85".. 2D hosted Mag85 1360/880L
did you send the driver back for repair? it's warranted even against 'dummy' :-D I will get around to making a similar light in a 'run' at some point. The sales will be handled off-site. I am aiming toward the 1164 due to a better match with several battery configurations and more consistent...- andrewwynn

WA 1331 instaboom!
high resistance is the key to saving a 1331 in a direct-drive solution... a PR adapter solution for example has 215 miliohm of resistance.. a kiu solution will have about 40+35 = 75miliohm.. that's the difference of .4 and .15V drop on resistance.. of course that resistance will drop the output...- andrewwynn

Osram Halostar IRC lamps NOW in a HOST w/beamshots
the lamp i'm aiming for is the 64367 .. running at 28+V.. 325W and just about 10,000L out the front. it should be quite a sight. Back to IRCs though :-D.. i'm amazed how much i like the 50w compared to the 65.. i run it in a 2D host with 16x2/3A (a couple dummy spacers in a 6x3 config and...- andrewwynn

Osram Halostar IRC lamps NOW in a HOST w/beamshots
hotdriver can handle up to 35A and 30V or so max... i'm making a special one to drive 12A at 39V out... let me know exactly what bat and lamp config you want to pair up.. email me vs talk off-topic or ask on my combo thread: http://cpfcombo.rouse.com -awr- andrewwynn
