My cyo premium has sat on my bike for coming up to 4yrs even when not active if has still been subject to all year conditions as it is on the bike I use throughout winter( low temperatures, driving rain, salt sea air ). The beams are to all intents identical too.
It's a great value light with an excellent beam pattern( full width of c-roads plus the verges ). The luxos which I was tempted by did have features perhaps pwa may like, on the luxos u it had light distribution variation by speed.... sadly they never put that on the lower cost B variant. So I opted for cyo premium and feel it was the right choice.
Edit: oh and I thought the edelux1 was effectively the original cyo with the edelux 2 being equivalent to cyo premium. The beam width is better on cyo premium/edelux2.
In the end I did opt for a version of the Cayo Premium 80 lux, with the daylight running and standlight. I've ordered it from Rose at just over £50, trying to keep to budget options rather than "the best money can buy". It is for commuting after all. The Cayo Premium seemed the best bangs for bucks option. Thanks for the recommendation.
The wheel is ordered from Spa. An SP (non-disc version) again as a budget option. I can cope with disassembly and sending it off for new bearings in a couple of years if it comes to that.
The rim is to be an Exal LX17 because it matches the tyre widths I use and it is only 3mm different in ideal spoke requirement to the still good Grizzly CSS rim on the front wheel that will be coming off that bike. So when the new LX rim eventually reaches the end of its life there is a reasonable chance that I will be able to re-rim with old CSS rim. Well, that's the theory. I'll settle for having to buy another LX17 if need be.
I'm going to mount the lamp from the bars, directly in front of (possibly slightly lower than) the front of the stem, using one of those twin arm B&M brackets.
The whole lot comes to a bit under £200, which I think is pretty good going.
I should start getting the components over the next few days and I will report on any assembly issues and, of course, impressions of the system in use.
Thanks to all for your thoughts, which were very helpful.
