    only thing is to be totally fair it would have to be in an equally dark place, and with an equal camera. not sure how much it would matter if not though, would probably still be useful.

    Would we be allowed to use Photoshop?

    I think it's a good idea - to be honest most people probably aren't bothered about the smaller differences that might be due to camera and location differences, but would like to see a general comparison.

    I'm assuming the picture is taken without flash... And it would be good to try and recreate very similar locations. Perhaps if you post something and give us an idea of how dark it is, we can find places that match it fairly well.

    How about rear lights as well?

    To make it even more useful, a few words on how easy the lights are to transfer between bikes, carry off the bike, operate on the move, reliability etc...

    hmmm...yeah, I see.
    well I'll post pics of my lights, a smart polaris 2 (3 led) and soon to be getting a BLT firewire.

    I've gone and purchased this light. As soon as I get it I will do a comparison with my cateye (el-500 I think)

    Ok guess I'll go first then:

    Cateye EL-530 first up using new duracell plus batteries:

    This is another shot this time standing well behind the light:

    This is the latest pic of these lights. The settings used are: f-spot: f/2.8, shutter speed: 1/4, iso: 400, white balance: tungsten. I could brighter pictures using other settings however they completely bleached out the ayup pics and this was the best I could get where you could see both pics with some detail. Hope this helps:

    Next up my new AYUP using standard li-ion 6 hour battery:

    and the is the update for the ayup from behind the light:

    Manual settings version of the pics. Details described in cateye section above.

    Can't fathom how to put a picture up directly on this reply. Tried image tags, file uploading but neither works so can only provide links to flickr.

    I hope to get a comparison of a Lumi 12w halogen and a 1920s carbide lamp early next week...

    That looks way brighter than mine - way to check mine out again

    Adding extra photos to my original post as there is a difference in how the el-530 shows up depending on where the camera is place when photographed. Don't ask me why.

    Thought it better to update here. Not really technical with my camera. They are just things you point and click but your suggestion below would probably explain it.

    Don't really want to overtake the thread with lots of different replies so maybe domtyler might see this here - I didn't do that because would that not defeat the purpose of the thread?

    Just turn the brightness up in photoshop before you post it.

    Guess the settings on the camera are going to make a difference. I used a "shutter priority" mode, went for 1/4 sec and set the ISO equivalent to 400. I did try a shot on auto, and the camera selected 1/8sec and it sets the ISO itself.

    Back in the days of C+, I thought someone had started up their own website with lots of bike light pictures on. Dunno where it is now?
