Convoy H2 bezel tightness improvement

[tenohfive]

Completely agree. During winter I use my headlamps for up to an hour a day, being able to just plug in a USB-C cable and forget about it is a real convenience factor. I wouldn’t ever want to have to choose one or the other (i.e. integrated charger but non-removeable battery) but having options is worth a small increase in weight.

Anyway.
Does anyone know what size star is on this, and if it’s possible to replace it with the below (Osram green emitter on a 16mm or 20mm star)?

16mm. It’s replaceable. But I can’t confirm if voltage and current regulation of the driver are suitable with that emitter.

I just got myself another H2 with LH351D. This time the bezel is straight, which is nice. But it’s still slightly protruding, about 0.5mm above the body.

I did the TIR-lens mod for my previous H2. I didn’t use the ar-lens and no “gasket” between the lens and pcb. Instead I made a spacer out of a 10 cent €uro coin between the pcb and body to raise the complete assembly. This coin is 90% copper. It’s 1.5mm thick after grinding it flat. The bezel sits a bit too recessed with it (just cosmetically). Next time I will use 50 cent coin which is 0.5mm thicker. That should make the bezel sit perfectly flush.

Now I had a chance to do a direct comparison between the modded (25 degree TIR) and original lamp with OP-reflector. In my opinion the modded one has more pleasant beam. It’s slightly floodier and very even. Of course some of the throw is lost but I don’t care. It’s perfect for trail walking and yard working.

I’m eyeing the H2 right now. Does it require a mod to fit the TIR lenses available on the Convoy store?

I used convoy’s 20mm lens too. It’s necessary to grind it’s diameter smaller (most of the top lip gets removed)

The copper spacer is optional (1.8 to 2.0 mm thickness is good). Without the spacer you need to use the original ar-lens and plastic “gasket”. So basically you just swap the reflector to a tir-lens.

In my opinion less lenses stacked is better, so I preferred the spacer mod. Also to my eyes LH351D’s tint looks better without purple ar-coating.
