I will drink coffee next time...</p> <p>@Arellcat, that thread is interesting, thank you for that. It would be fun to do something similar. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=8804#post-89592 Fri, 02 Nov 2012 00:15:17 +0000 Its_Me_Knees 89592@http://citycyclingedinburgh.info/bbpress/ <p>@Kaputnik "Anyone got a photography light-meter?"</p> <p>Moi.

The difference is so dramatic that I wonder whether that bloke just has rubbish reflectors or whether his tyre wall and/or mudguards were obscuring after all. Your photo makes it pretty clear those spokes are working the internal reflection magic.</p> <p>One thing I would like to see is whether my bodgey ski glove cuffs work. I know they reflect, but I don't know if they obviously look like the hands of a cyclist indicating to turn, or just like confusing white shapes near a red bike light. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=8804#post-89573 Thu, 01 Nov 2012 21:08:38 +0000 kaputnik 89573@http://citycyclingedinburgh.info/bbpress/ <p>Spoke (and Ortlieb) reflectors in camera-phone LED;</p> <p><img src="http://farm9.staticflickr.com/8190/8145699222_a114fd253a.jpg"> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=8804#post-89568 Thu, 01 Nov 2012 20:28:06 +0000 Uberuce 89568@http://citycyclingedinburgh.info/bbpress/ <p>I unwittingly roped a passer-bike into a two-person Harrison Park testing session just now.</p> <p>He had the reflector spokes that Kappers and Rugg were Tweeting about the other day, and after he'd turned off to go down the path by the playpark in West, I cheekily turned my handlebars to see how well they showed up. </p> <p>The answer, disappointingly, is not at all. I know I had the angle right since the Scotchlite trim on his tabard and pannier were shining with that unnatural ferocity the stuff only gives when your eye is near-parallel with your light source, but I couldn't see any of the spokes. </p> <p>Pretty sure it wasn't just because his tyres were obscuring them, but this is exactly the kind of thing I have in mind: getting our empirical hats on and experimenting away.</p> <p>So: </p> <p>1)PY as normal on either the 9th or 16th<br /> 2)Evening meet in some dark central place. Harrison Park/canal; Innocent; Holyrood Park; Hermitage, etc</p> <p>@Arellcat if it's going to have a good turnout, I hereby beseech Dave to turn up with his trailer. I suspect but need to test that white binbags with lights inside will make awesome Tron trails. Two Carry Freedoms will allow red lights in the second trailer(mine) for awesomer ones. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=8804#post-89561 Thu, 01 Nov 2012 18:05:17 +0000 Arellcat 89561@http://citycyclingedinburgh.info/bbpress/ <p>I wasn't drinking coffee either. Tea, Earl Grey, hot, as Jane from next-door-to-LBB knows of me now.</p> <p>If the digital SLR brigade is thinking of getting involved, perhaps it's time for a proper CCE Light Testing evening, along the lines of the <a href="http://yacf.co.uk/forum/index.php?topic=11751.0">yACF event</a> in 2008? We could make it a "bring your own bike and bring your own lights", to compare each one as used by the owner, as well as an objective, scientific, like-for-like comparison. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=8804#post-89558 Thu, 01 Nov 2012 17:40:10 +0000 Wilmington's Cow 89558@http://citycyclingedinburgh.info/bbpress/ <p>If the weather is as it was for the tandem meet... then yes.

The shine-against-a-plain-wall-from-the-same-distance test is tricky to arrange when there are dynamo systems involved. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=8804#post-89554 Thu, 01 Nov 2012 16:44:37 +0000 amir 89554@http://citycyclingedinburgh.info/bbpress/ <p>I find evenings harder for meet-ups but I have got an interesting-ish front light: a B &amp; M Ixon IQ. It's pretty bright with two settings but the beam is quite well shaped.

Also we could do a swapshop thing and bring in all the old lights we've nto got round to disposing of.</p> <p>Fun bit: coffee, cake, blether.</p> <p>Date: Need to wait until it's still dark at 8-ish, but not so late as to be pointless, I guess. </p>
