    I wish someone would make a cycling light based on those 5W Lumiled Luxeon LEDs. They're meant to
    be excellent for illumination and not just for being seen. Does anyone know if anybody makes them?

    They're definitely being developed (tinyurl.comr9t4 for details of a home-brew version) and
    it can't be long before the big manufacturers bring some lights out using them. The benefits over
    halogen are just *so* great they'd storm the market place.

    I suspect www.martin-jones.com may be what you're looking for.

    cheers, clive

    That looks about right. Now to find out prices. Thanks!

    They also sell these LEDs 'as is' but I'm not very good with electronics so don't want to waste
    ?12 on something I'll probably break.

    I'm not entirely convinced by that website. It claims the LEDs are several times as efficient
    as halogen bulbs, but googling suggests only 23 lumens per watt which doesn't sound
    particularly brilliant (for colours, it's better, but that isn't relevant to front bicycle
    lights). What am I missing?

    Just looked at www.ultraleds.co.uk available for 11.50 UKP. They look quite interesting things!

    Those are the 1W ones but even so would be fun experimenting, if a little expensive if you are prone
    to breaking things, like me.
