    Which is the best thrower between these?

    I actually received my Lumapower Signature LX a couple of days ago and I'm intending to post a review of it here when I get the time. Most expensive option on my list, but hey. It's nice and compact - just about the right size for me to EDC - feels good in the hand and the flood is phenomenal...

    The Dangers of Working with a High Voltage Supply

    I wonder what our lab technician would say if I tested that in the lab on Monday...? Actually (she's a very liberal and nice woman), she probably wouldn't bat an eyelid - the PhD students do worse, I'm sure. Whilst, I've seen the one-hand rule mentioned multiple times, I don't think anyone has...

    Which is the best thrower between these?

    I do like the look of the RRT-0, but, ultimately, it's at least £90 here the in the UK, which is above my budget considering I then need batteries and a charger. It's the two Lumapowers that are really catching my eye at the minute, especially that Signature. I wish I could find somewhere in...

    Which is the best thrower between these?

    Funnily enough, I was going to buy one over on CPF Marketplace, but the cursed time difference meant I was beaten to it. It was for the best, since I'd really like a bit more power...although anything will be a step up from the old LED Lenser. I'm trying to experiment at the moment using the P7...

    Which is the best thrower between these?

    A ringy beam would sort of put me off...especially as the Fenix is already theoretically the dimmest light there. What sort of throw are we talking about? If you were standing on a dark night (not much moon) and you shone it across a riverbank, for instance, could you illuminate an object 50...

    Which is the best thrower between these?

    I hear what you're saying - I sort of think it might be on the large side myself. The torch I lost is exactly the same size as this: http://ledco.co.uk/content/productView.aspx?prodId=29 (That isn't the exact model -I had one with a decent laser instead of the red LED.) I wore it (and plan to...

    Super-dim AA light

    Not trying to be funny here, but in all seriousness, how about a Maglite AA (or AAA) keychain incan?

    Which is the best thrower between these?

    Okay, I'm an LED Lenser fan *ducks* and I'm used to being able to focus and throw the beam a very long way...however, I lost my EDC Lenser in a taxi or somewhere similar (should have had a lanyard on it. :(), so I'm in the market for a new torch. I thought I'd strike out and try another brand...

    Tritium microspheres + photovoltaics = ...

    It's just a pity that the tritium/phosphor combinations used for illumination really aren't all that bright, so even a good photovoltaic cell isn't going to generate that much current/voltage off of one, surely. Not sure about simply trapping the tritium and using the beta particles (electrons)...

    Simple Electronics question

    Watts are a measure of power. Power is energy per second. Therefore, as an example your standard 1000W kettle uses 1000 Joules in a second. (Or 2000 Joules in two seconds or 500 Joules in half a second and so on.) A Joule is a unit of energy (or 'work done') and is defined, IIRC, as the...
