    SF Hellfighter custom power cable? Cigarette adapter?

    I'm not sure of the input voltage range on the hellfighter, but I do know they can run off the BA 5590 batteries ( http://www.batterystore.com/Saft/SaftPDF/BA5590.pdf ), So the voltage range includes at least 10-15V SF's website says they run for 1.5 hours on a single cell, so assuming it runs...

    What is the difference between energizer max and energizer industrial?

    http://data.energizer.com/PDFs/en91.pdf < industrial AA datasheet http://data.energizer.com/PDFs/e91.pdf < energizer max datasheet Looks exactly the same to me, just the EN91's are designated "NOT INTENDED FOR RETAIL TRADE" most likely a labeling/legaleze issue, as the max's probably have...

    SF Hellfighter custom power cable? Cigarette adapter?

    If you want to mount it on a specific vehicles, I'd say skip a cigarette adapter, and adapt something like an Anderson power pole for powering it. But if you want to use it as a handheld spotlight, http://www.digikey.com/product-detail/en/APP-001-20AMP/APP-001-20AMP-ND/2057904 appears to be...

    Flashlights are getting too bright, Lumens race getting out of hand...

    Put your finger in front of an XPG or XML being driven at full power (not touching it, just a few mm in front of it) and get back to me on how optical heating isnt an issue because LEDs dont emit any IR.

    Low Current Lights?

    a single 5mm LED in a dark room, with adjusted eyes would be enough to light the room. However I'm not sure if thats exactly what the threadstarter was talking about. http://www.amazing1.com/products/Transformer-3000V-10mA.html a 20mA short circuit current would mean you could use that to...

    Battery Pack Rebuilder Recommendations?

    If I were about 2-3 months ahead on my battery tab welder, I'd say I could do it. But at the moment its just a box of caps and semiconductors. I know lux luthor has a battery tab welder, but I dont know if he does work for others or not. Its not Li-Ion so the assumed risk should be pretty low.

    LED CAN LIGHTS STROBE WHEN THE SWITCH IS OFF

    Most TRIAC based dimmers have a snubber capacitor across the switching element. This keeps the rate of rise of voltage from stray inductance in the wiring and any slightly inductive load from causing the triac to self-trigger. This capacitor will have a capacitive reactance which lets though...

    Do the xenon bulbs in mini mags emit any gases when they blow?

    As far as LEDS go, I'd not worry about radon, and worry more about the bit of gallium arsenide in there that could be put into the smoke if you make one fail in a manner which lets out the magic smoke. Though the burning silicone/epoxy probably presents more of a threat.

    TK40 fixed after a year of not working!

    Re: Fenix TK40 Switch: How does it work? Good thread, Ive had a TK40 that work got me for over a year now, and its survived a few falls, one from ~10-12 feet onto concrete, with just a bit of dinging on the bezel ring. I'll have to keep in mind to look at the battery cartritge if it starts...

    Car stereo battery lots o $$$?

    Shame on you guys for not mentioning the big 3. BudK touched on one however. A '12v' system runs at ~14-14.5v when the alternator is powering things. When a SLA is under load its output voltage will be 12.5-13.0V or so when its full (depending on load, internal resistance etc) All energy that...

    Question about led surface mount soldering

    Paste is definitely easier if you have a stencil, if you dont have a stencil then youre just dropping a blob on, and its easy to have excess squeeze out, and have little micro-beads of solder form that can potentially short out stuff. If youre getting good results with pre-tinning, its fine...

    Series charging a Dyson DC16 li-ion pack

    6 minutes of run time, or a 10C draw, and 1000mAh would make me think its a Li-Mn pack similar to most power tools. While balancing wouldnt hurt, not balancing isnt as huge of a risk as if you had rebuilt it with Li-Co cells. Also, at 10A a holder may become questionable unless it has good...

    Wolf Eyes Sea Lion Hunter SST-90 green mod

    As long as its a decent constant current driver and not something cheesy like just a resistor inside, it should work. (which it appears that what they are on their website)
