Dynamo Lights

I’ve got one, seems fairly well made. I haven’t really put it through the ringer but I did email the guy who makes them a fair bit before buying asking about waterproofing, heat buildup on descents etc and failure rates and he seemed pretty confident in it, he said they’d had no failures thus far.

If I was going to be using it extensively in all weathers I’d be tempted to strip off the plastic shell (if there’s a weak point then the plastic outer case is it) and coat the components in epoxy or similar, some of the other units are built this way and it pretty much makes it indestructible.

If you want the email conversation (I’ve just looked and it’s more detailed than I remember) drop me a message and I’ll fire it over.
