I’ve never seen them properly check lights at SITS or MM. I’d imagine if you went out with a really dim light they might stop you, but they don’t come and check exact power consumption. There were a lot of people using LED lights only at mayhem, and they will all have been under 10W. It’s probably easier to leave it as ‘10W min’ so they can use a bit of discretion rather than say ‘equivalent of 10W’ and get people arguing about it. You are supposed to have a backup light, although that can just be a little torch so that you don’t walk into trees or get ridden into while pushing back after your main light fails. A head torch is nice for that so you can use it to fix punctures and the like without using your main light. Having said that, if your main light is only 3W and is headmounted then that’s less important.
The important bit is to practice night riding with the setup you’ve got to make sure it’s enough, and to make sure the batteries last long enough.
My helmet-mounted light is actually a 10-watt bulb, but it’s in a case with “5w” stamped on the side - I’m always a bit paranoid that “lamp inspectors” will pounce on me and make me dismantle it to show them the bulb, but I don’t think they’re really that petty. If it looks like a reasonable lamp and you’re happy riding by it then I wouldn’t worry. The biggest problem I find is that a 10w bulb is perfectly adequate for unicycle speeds, until somebody comes past with an unfeasibly bright array of HIDs, then you’re blind for a couple of minutes
I’ve never known anyone to check, and nobody will run into you if your light is too dim; that’s what their own lights are for. It really comes down to what you’re comfortable riding with. I would have thought a 3W LED should be ample though.
I regularly ride with a Cateye Doubleshot which must be fairly close to that (I can’t actually find a figure) and it’s perfectly acceptable; there were people at Mayhem with Dinotte lights which (IIRC) come in 3W and 5W varieties, and they seemed perfectly bright enough.
Last year it was about 7 miles ish. It might vary a bit, bit it’s unlikely to be much different - certainly not more than ten. It’s nowhere near as hilly as Mayhem either, so lap times are quicker (until it got really muddy :o)
It’s mostly Cokerable, it depends on how good your Cokering is… The course is less hilly and less technical than Mayhem and there were some fairly long fireroad sections last year where having a Coker really helped.
I find a Coker is a bit too tall in the woods, I tend to bang my head on branches.
Excellent. Now the important stuff - does anyone have a gazeebo? I can possibly go and borrow a uni one again, but that sort of assumes that they haven’t yet noticed that I’ve not given all of it back after Mayhem yet. Corner pieces aren’t important, right?
