I don’t think there are any hardware changes to the driver. I think it’s different versions of the firmware that are changed. At least it doesn’t state any hardware changes on their website. All their different firmware UI’s are listed here.
In New Hampshire, just like in New Jersey, and shortly after the Boston tea party, we started calling them Flashlights, just to be different from those across the pond. After selling one of my 5 D4vn’s and 2 stock d4’s, I’m still strangely drawn to this. The only problem is it still leaves me with 9 d4’s…one question. When you click the switch, does it always come on in low, even if you switch it off from high?
So I’m clear. They charge $20 to $30 more for the D4/D1/D4S line just because it came from them with a card stating output and a signature? Nice. I’m in the wrong business. To think I just paid $40 to Int’l Outdoor instead of $70 for a XP-L Hi 5000k.
I wouldn’t say that is correct
for the d4vn
he states,
◦Upgraded optics on all models for throw
◦Blurred center optics window
◦Refer to factory link for great unique UI
So its not completely stock, and its engraved by him to show it is one of his lites
and you get his warranty service which is exceptional.
I have this exact light and LOVE it! Definitely worth the upgrades. Nice throw, more focused “hotspot” but with awesome spill as well. Vinh is a stand up guy who makes some great lights/ mods. He stands behind all of his work. Well respected.
At first I had buyers remorse when I ordered my d4vn, but once I had it in my hands, manOman It’s worth every single penny he charges. I basiclly never use my Autrolux s41 and s42 anymore.
