    I've looked at these a few times on ebay. They look pretty much perfect for my limited needs.

    LED Torch

    I've purchased some real crap fom unknown Hong Kong suppliers though.

    While I'm musing, has anybody here tried these and can comment on the quality?

    IF your looking for a cheep but bright small back up torch these are very good.

    I was so impressed with the one I saw whilst diving the cenotes in Mexico last month I bought two, while I was there.

    When compared to my Tektite Expedition it blew it out of the water for half the price.

    The Aquastar has a very tight beam and is very bright for a 3w torch.

    That one was on my list as a possible as well. Problem is it's AAA cell not AA, if I read the ad right.

    All my cameras, flashes and surface cameras now use AA, to minimise the range of (rechargable) batteries I need to take to stripy fish land. The chargers adapt to AAA, so its possible, but I'd prefer AA if I can get it.

    Yes they are AAA but the good thing about it is it will actually still run with only 3 x AAA. Given the size of AAA's and the 5+ hrs of burn time. I think you'll get a decent weekend diving out of one set of batteries.

    When it get dark I will do a beam spot shot of both for comparrison, and try and UL it here.

    Anybody had chance to compare this with Lenser Frogman
    http://www.divemagazine.co.uk/news/article.asp?sp=368617332571534903370&v=1&uan=2122

    I had one of these and it was superb for it's price, and was in BCD pocket on every dive - but a heavy handed dive centre guy crushed it with a tank on a recent dive - so time to buy a replacement.

    Interesting that you bought these in Cenotes - that was where I was diving.
    I thought I would be OK ... had a dive policy .... (Westfield) but when I made the claim, there is a £50 excess ... so no pay up for the torch.

    Battery technology has moved on hugely in recent years and AAA are now taking over where previously only AA would suit.
    The Duracell Ultra M3 is probably ‘state of the art’ in AAA batteries.

    The key thing is to look at mAh rating, as the voltage of AA and AAA are the same.

    1200 mAh is now available on many AAA batteries .. but also be aware that rechargeable will typically be aprox 30% less, and a lower open ciscuit voltage.
    So they cost a lot more (+cost of charger) burn time per charge is a lot less, you do get recharges true, but that means you also need to carry charger.

    As I mentioned in previous post I had a Lenser Frogman … glad I never bought rechargeable batteries & charger, in 2 years – still on original batteries.

    rechargables also tend to have a slightly lower voltage as well so possibly not quite as bright.

    Seen a lot of good comments on expedition ... so really would be great to have some more details of comparison between the 2 .... beam comparison pics would be great.

    I was under the impression that this applied to only the older Ni-Cad rechargeable batteries and not the more modern NiMh ones? The latter are supposed to be at least as good as the conventional alkalines. Furthermore, one can now get Lithium AA & AAA batteries which are significantly longer lasting and only slighly more expensive than their alkaline counterparts.

    Well no option on NiCad .. they are now discontinued due to heavy metal issues.
    Nickel-oxy-hydroxide is one of the current high power designs of disposable, and Alkaline batteries are currently better.
    NiMH rechargeable are better performing than NiCad .. but they still have reduced terminal voltage, 1.2V typically.

    Thnx ... certainly looks brighter - it must have a much better reflector, as it looks like the same 3W bulb.
    The torch interests me ... and Googling around came across this review, care to have a read and give me your comments ?
    http://www.divernet.com/cgi-bin/articles.pl?id=6345&sc=1002&ac=d

    Did you fins the on/off mechnasim any issu e?

    It looks like a choice between this and a Lenser Frogman

    Yes I've seen that report. Both of the torches (Tektite & Aquastar) have a double 'O'ring setup, with a twist on/off bezel. As for it coming on in my pocket, thats not an issue I have mine bungeed to my shoulder strap for ease of use.

    Having used both of these, if I was buying again for the 1st time Id go for the Aquastar, as its lighter, smaller, brighter, and much easier to stow on your kit without it being in the way.

    One thing to remember if you do buy one of the aquastars, put a line of electrical tape or similar around the joint on the head for the bulb access, to aviod unscrewing the head whilst turning it on and off.
