    What's the big deal about off-center emiters?

    Big problems can occur with badly aligned emitters: 1) Stress on the emitter's dome perimeter causing the dome to come off. 2) Broken internal emitter wires under/inside the dome due to high mechanical lateral force from the reflector, especially if it's a soft dome like many SSCs. 3) Emitter...

    Single cell red CREE LED flashlight?

    I bought two of these red crees(http://www.dealextreme.com/details.dx/sku.1776), they are extremely bright. I was seeing spots for a couple of minutes after having powered one bare for just a couple of seconds with only 300 milliamps. I'm not sure how much current they can handle, it doesn't...

    What 2xAA lights have the best beam patterns?

    The Fenix L2D (180 lumen cree version) is an absolutely superb 2AA power supply regulated flashlight that delivers a nice strong medium sized smooth spot even with common rechargeable batteries. I doubt one can find a better 2AA flashlight that can perform as good as this light for the price. I...

    ok got it down to 2 flashlights, what do you think?

    The Fenix L2D (180 lumen cree version)is the Holy Grail of 2AA powered flashlights. Just get it and don't look back. Yes, the initial price is a bit more but in the long run it may be less expensive since it performs so very well on common inexpensive rechargeable batteries. With intermittent...

    Fenix E01 + magnets = weirdness

    Retro Encabulator video, nice find. IMHO, Tim Allen should have hosted that, it would have been too good.:laughing:

    “900LM” SSC P7 review - a great bikelight?

    The "ring" is what holds the switch assembly inside the flashlight's end cap and it's made of metal. The spring loaded negative terminal is held in place by a plastic retainer. That has to be unscrewed and removed first before access can be made to the metal ring. The metal retaining ring is...

    The Ultralife Lithium 9V Smoke alarm challenge

    Re: The Ultralast Lithium 9V Smoke alarm challenge I did, and I'm done with the Ultralast/Ultralife experience. These lithium batteries did not last a great deal longer than leading brand alkaline batteries. When it came time to change them I often found they have swelled up inside the...

    Ooh, where can I get those springs?

    That's a valid concern considering the level of soldering skill this task requires. Most of my lights have properly soldered-on springs and their bonds have yet to fail. Me and my lab grade Weller temperature controlled soldering station are ready when and if these springs ever become...

    “900LM” SSC P7 review - a great bikelight?

    If the Aurora P7 light you are running is the same (or similarly designed)one I'm running (http://www.dealextreme.com/details.dx/sku.12588) make sure the aluminum retainer ring is screwed in tight! The ring is inside the tail hiding behind the black plastic negative terminal plunger. A decent...

    Ooh, where can I get those springs?

    The spring in the photograph appears to be the perfect size, tension and it's gold too! The spring maintains constant battery contact under conditions where vibration is present. It also provides excellent mechanical shock protection for the driver board and battery(s) should the flashlight...

    “900LM” SSC P7 review - a great bikelight?

    A couple of hose clamps and some radiator hose works very well in keeping the lights secured to the bike's handlebars. The bike in the image has no shock absorbers and it's frequently taken off-road and ridden in a rough manner. The hose clamps and grippy protective radiator hose rubber does a...
