I think Simon mentioned a UI update (single click for off instead of click and hold) as a possibility as well as maybe weight reduction and better strap. Built in charging has also been discussed.
I wouldn’t say that emitter options are out of the question. He’s been asked about it, so he’s knows there’s the desire. And he’s been switching it up with emitters lately. So who knows for sure.
With all due respect, that’s not quite how I would communicate constructive feedback. And considering Simon sells TIR optics in his store, I’m pretty sure he is aware of them.
Thermal path is really good. I just finished up the MCU swap last night. My runtime test is wrapping up right now. RampingIOS with it’s thermal capabilities are just what the doctor ordered!
I coded the MCU to try and stay at 60°C. The body stayed at 56-57°C, so very close to the MCU’s temp.
Is it necroposting if I bring this back from the dead? I’m really interested in the current h1 situation, but it seems to still be the same as it has been for the past year or so.
Yup! I just got my Yajiamei shipment in a couple weeks ago and swapped mine for a pebbled TIR as well. Makes it much better for up-close tasks.
I needed to be careful about the height. I first tried without the reflector centering gasket and there wasn’t enough height to push the MCPCB against the shelf. It must have been floating a little because the LED started to turn blue and the bottom of the TIR started to melt. I stuck the gasket in there to add some height and it’s worked well since.
In addition to updating all My H1’s with your drop-in MCU’s I changed the locator LED to blue, added a Sofirn Gummy and made up a custom camo headband. Ramping OS with a locator LED makes this light shine IMHO
I’m a big fan of convoy and the H1 looks great, but I wish they made it lighter since that is very important for a headlamp.
My H03 weighs 44g, and I can feel the extra weight of my 56g wowtac A2, so for me that 70g of the H1 is unfortunately enough to keep me from getting it.
Gchart, that stock lumen vs time graph doesn’t look very regulated. Is that just heat and a high Vf LED that makes it look sort of direct drivish?
I agree the graph kinda looks that way, but it’s using the 7138 linear regulator (a cousin of the 7135).
I haven’t weighed it, but I think the updated version of the H1 trimmed down the weight a little bit. I agree of headlamps it might be a bit heavy. I’ve worn it for a few hours at a time before and it is a bit heavy but that weight also helps provide extra thermal mass. Just depends on your needs in a headlamp.
I don’t really notice a difference in weight between the H2 and my lightest light, the Zerbralight H600. I just weighed them with the same battery and stock headbands and came out at 150g vs 120g, so definitely a difference but the better headband seems to counter this extra weight somewhat. Sofirn SP 40 wins for heaviest 18650 light at 155g.
