Dynamo Lights

diode test setting

I just get a 1 both ways

Actually I get somewhere between 500-1500 on first contact in one direction, but it goes straight back to 1

That’s probably the stand light capacitor charging.

The test voltage on one of those things might not be enough to make current flow through the LED, so I don’t expect you can tell much with it.

The best way to test the light is to connect it to a dynamo and spin the wheel. You can use the meter to check if the dynamo is outputting a decent voltage. Set it to V~ and see if you get a reading. It will be 20-100V with no light connected and 3-10V if you connect at the same time as the light.

Thought about this for my bike, VO guards though. Are you confident the guard is stiff enough so the light won't bounce or wobble a bit? Small bounce = big beam movement. I was thinking of a strut like a rack support that went from the fork mid eyelet and looped over the guard. It'd need an L bracket to fit the guard and light but that's what custom builders are good, at right?

Just get an extra fender strut. You can run it from the drop out or from mid eyelets.

Can the Edelux 2 power a B&M rear light, or is it their own one only? I seem to remember there being something about them being DC.

Also the cable looks hardwired, anyone ever tried replacing it? (thinking about the inevitability of deciding I want it on a different bike in a few years)

The Edlux has no issue with a B&M, done it a few times. You can always trim a wire and splice in quick connections.

Can't seem to find an answer to this.. Does the power switch on the IQ-X toggle the rear light as well, or only the front?

vvv cheers!

Does both front and rear on mine

Had this printed by @Stonehedge a while back. Thank you again if you happen to read this. It lifts the light up off the fork crown, uses the underside of a garmin mount.

It’s been there for a few thousand km, and has been superb. Wiring is still the temporary job I did the 1st day. I’ll get back to it.

Ooh, would love a file for that. STL would be good but STEP or something else I can open with Fusion would be even better. @Stonehedge

Edelux II works with B&M; think it's the Exposure lights that only work with their own. I just spiral the cable up the fork leg to leave me with enough slack for future changes, but IIRC SON will repair/replace cables for a fee (and offer a 5-year guarantee against failure anyhow).

Re. IQ-X, it's available for ~£75 at the moment, which makes it the best bang for the buck powerful light at the moment; the IQ-XS is 70% of the light for about half the price (from Germany at least), so more than adequate for town use. The IQ-X can be mounted upside down as well, which is nifty. The Edelux II has better build quality and warranty, and is prettier, but whether that's worth the extra £50 probably depends on how much of a bike tart you are...

@wot designed his own part. I've got an STL for it but maybe wot can help with step...

Cheers, yes my sensible side has almost won out.

Mine almost did, but then the Shiny! triumphed...

Anyone here interested in trading their polished silver upside-down Edelux 2 for my black one?

@Tijmen PM some contact details. I can share a step.

Would you be interested in an new/unused polished-silver IQ-X?

Sorry. Already got one of those. For a retro Rando bike so the edelux is a must.

It was a long shot :)

I’m not wild about the bracket for the IQ-X, and I’m newly the proud owner of a black Son hub (so would quite like matchy matchy malkovich malkovich).

So I’ve see this solution mentioned, but never executed. Here are some rear dynamo wires heat shrinked to the rear brake housing.

Neat! The next time my hydraulic hose comes apart this is what I’m doing.

That's how mine is set up, works well. I ran the exposed section of brake inner inside a teflon tube and heat shrink wrapped the rear light wire to that so it's covered for the full length.

Spiral wrap looks like a good method too. Perhaps less faff when you change cable-outers.

Bought 2 aliexpress dynamo light (fake supernova?) silver and black.
Impressed by how quickly they have arrived (less than 10 working days).
Soon I'll use the silver...
