    My 'blinking' DDR30 is now....

    hmmm....TK75 and a TN30....would be interested to here your thoughts on those two when they arrive...

    Lipo Battery info needed

    Yep, 22.2v is 6 cells in series (6s). And they use 3.7v for the cell voltage....which does seem weird as fully charged they're 4.2v. (Dunno.....anyone?) I had a feeling that storage voltage was around 3.85v per cell or thereabouts. Safe discharge is not below 3.5-3.6v per cell (multiply by 6...

    Spark SX5- second thoughts

    Re: Spark SX5 a disappointment Had to look up the SX5 - I hadn't heard of it. I see what you mean about the cable. What where they thinking? Most that I've seen run the cable along the headband via a couple of clips (like Petzl do) and that seems to be fine. I have the SD6 with the add-on...

    Lipo Battery info needed

    Some good info here: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries I try to re charge before I hit 3.6v per cell or thereabouts. And yes, 4.2v per cell is what you generally charge them up to. Any higher can result in a mini BBQ event. There's a good article at...

    Want better runtime from NiMH batteries?

    Ditto here. I have a **** Smith (Aus brand) 'intelligent' charger that would often tell me my batteries were charged well before they should have been with resulting rubbish run times. Lots of reading here and I bought the MH-C9000. Now I can easily sort the good from the bad and revive some...

    Review of / Measurement on Charger Xtar VP1

    Thanks Matthew. Both my MH-C9000 and disk drive power supplies measure 12.11 and 12.04 respectively with no load so I would assume they are regulated supplies and as both are rated to 2 amps, I would assume they are interchangeable with one another. Assuming the VP1 power supply is similar I...

    Review of / Measurement on Charger Xtar VP1

    I have one of these on the way also. If voltage & polarity are correct, can I use a higher amp rated power supply? (I only ask to save having yet another power supply taking up room on the floor!! - there's already a 2amp 12V supply that powers my hobby charger and a disk drive...so if the...

    Shelf life of unused rechargeable batteries?

    I had a bunch of NiMH's sitting in a draw for 8 - 10 years or so and ended up buying a C9000 charger to sort them out. Most of the energizer 2400mah batteries came back up to near a full charge after 3 or 4 cycles. Quite a few had the 'high' resistance on the charger and another 20 (mostly...

    Has anyone ever used strobe mode?

    Anyone actually use Strobe? I am curious to know if you have ever actually needed to use the strobe function on a flashlight - I have half a dozen lights with this function and sure, I've flicked it onto strobe every now and then but realistically, I cannot ever see me using it....well, I...

    Sunwayman D40A - Another 4AA compact thrower

    Re: New Sunwayman D40A - Another 4AA compact thrower hmmm...maybe a pics worth a look. Doesn't feel any harder to use than the wrist loop and seem to trap itself when you try and drop the light. Maybe the trick is that I'm not using a lanyard with a clip attached...

    Sunwayman D40A - Another 4AA compact thrower

    Re: New Sunwayman D40A - Another 4AA compact thrower I've used a slightly smaller landyard than supplied - it drops down between my two middle fingers and I then I can wrap it back up over my little finger and tuck the loop over my index finger. Seems pretty secure as I can't drop the light...

    Sunwayman D40A - Another 4AA compact thrower

    Re: New Sunwayman D40A - Another 4AA compact thrower Thanks for the photo of the red led low battery warning light....which I can't see mentioned anywhere in the manual ?! Raining here too last night but was impressed with the beam - not particularly throwy, but an excellent mix of throw and...

    Sunwayman D40A - Another 4AA compact thrower

    Re: New Sunwayman D40A - Another 4AA compact thrower One thing I quite liked - if you turn it off during moon-mode, it remembers it for the next time you start it up. So you don't have to do the press and hold of the power button every time. I know it's a small thing, but very handy for...

    Spark ST6 360 died

    I bought an SD6 earlier in the year and it's been a great light. Particularly handy when camping and using the magnet to attach it to the inside roof of my van. Lovely even flood and good selection of levels via an easy to operate interface.....except for the double clicking for turbo...

    Spark SD6-460NW Comments

    Just picked up the 500CW version and am very impressed as a head torch. I thought it might be a bit bulky on the head but it sits there pretty comfortably. On max it casts an even pool of light out to 40-50ft or so. Plenty to walk around with at night. Great for lighting up a shed or room...
