I’m currently re-considering the Convoy H1. 
H1 seems attractive because it’s smaller, lighter, and potentially more water-resistant—no charging port or rubber flap, which also simplifies modding or repairs. Unfortunately, it doesn’t come with the B35AM or a buck/boost driver, only the 3/5A linear driver.
I was previously set to avoid linear drivers due to their inefficiency, but I’ve read that H1 now has a regulated driver (non-PWM), which makes it more appealing. This also saves me the trouble of hacking a TIR lens to fit the H2, as Simon offers the H1 pre-installed with a 60° TIR optic.
According to info I found, when ordering the H1 with a TIR from the store, a copper shim is included to adjust for the reflector vs TIR depth — so it’s properly supported and not just loosely dropped in.
In Grizzly’s review, I also saw Nick’s comment about fitting a 2mm tall magnet under the tail spring. This sounds like a clean internal mod (vs gluing something on the outside). Has anyone done this? What diameter magnet fits under there? The tailcap’s OD is ~24.5mm, so it must be smaller than the 25mm magnet Simon sells.
Lastly — and this is what really surprised me — I noticed that Simon’s store still lists “219” for H1. I assumed that meant the newer C or FT series, but turns out he still has the real thing: Nichia 219B R9080 4500K. In 2025! That made the decision easy for me.
So the current plan is: grab the legendary 219B 4500K in an updated H1, with TIR installed. I don’t think I could go wrong at this price. Since the original lukewarm reviews, it looks like Simon quietly upgraded a lot — driver (UI), TIR support, wide blue strap — and paired it with one of the nicest high-CRI emitters out there. I honestly don’t think there’s a comparable option right now, even at double the cost.
