3W? or 1/2W?

    This looks like the Smart 1/2W, which is very nice in its own.

    3W would be very nice though - same as a Magicshine MJ-818

    I have an almost identical light and it's definitely 0.5W. I use it everyday and I change the batteries maybe 3 or 4 times a year.... If it were doing 3W I would have to replace them more than once a week.

    It might also be a 0.005W simplest led. It just looks like a Smart 0.5W, who knows what it really is...

    I have the Planet Bike Superflash and it looks exactly like this! I bought TWO of them, and paid 5X this price each!
    What's up with the scrubbed LED driver IC markings?
    What are they trying to hide?

    ~£18 ouch, you know you can get the official ones much cheaper? ;)

    I'd be tempted at getting another one or two, but I already have enough. I might just get one to compare and post back here.

    Also a handy spare mount...

    And agian, it looks just like it, it doesnt mean that it is actually the same. Maybe it got a crappy led and not an amazing one like Planet Bike's one got...

    Model: XC-744L

    I can confirm that the main led is definitely 0.5W.

    Google "Model: XC-744L" and have a look for yourself.

    The product description states on two other sites selling this light that the led in question is 0.5W.

    However, if the build quality is acceptable and this light does in fact produce a 0.5W light, this is still a very good deal.

    Clean up your act DX!

    I received this light.
    I measured the current while the main led is constantly on. Current: 38mA
    So, the power consumption of the device is 3V * 0.038A = 0.114W

    I did actually disassembled the light and found that the led looks like

    Ouch, 0.114W is a big drop.

    I wonder what our Smart/Superflash 0.5W officials actually draw though - anyone avalible to test? (cant do it here for a few days).

    Just got one, it says 0.5 watt on the packet and I measured a maximum of about 0.053 amp draw from the batteries, with the main LED steady on apparently at full brightness, making it about 0.16 watt; although mines got a bad/temperamental connection to the main LED and keeps going dim and out (I'd guess a dry solder joint), so maybe there would be a slightly higher current if it was working properly, although I'm sure it wouldn't draw very much more.

    That said though, it is very bright while it works, so if I can get it replaced with a good one, I'd be more than happy with it.
