    [Advice Needed] XHP70 12v vs 6v and Dive Light Design

    Does that apply to dive lights as well? Based on my knowledge of electronics it shouldn't be a problem but I'm used to designing transistors, not flashlights, so you never know :P The dive lights I do have don't have grounded hosts, the circuit is fully contained inside.

    [Advice Needed] XHP70 12v vs 6v and Dive Light Design

    Got a response from them: Also I realized there's a design flaw in my design... It seems a lot of these circular drivers have the negative input on the outer edge of the PCB. Meaning if the driver is sitting below the LED in the diagram above, it will be grounded to the light head case. I'm...

    [Advice Needed] XHP70 12v vs 6v and Dive Light Design

    Great! I will investigate Fresnel lenses, I'm a huge fan of optics so I might lean towards an aspherical lens but we'll see. One last question and I think I'll have enough information to push forward: So with BPS as a backup, I'm assuming you use the driver as the primary determinant for when...

    [Advice Needed] XHP70 12v vs 6v and Dive Light Design

    Hi DIWdiver! Very helpful writeup, thank you! Your 6V arguments are pretty compelling, this light is intended to be a recreational light and as such maximum efficiency takes a back seat to ease of use and design. Based on your information, it definitely seems like 6V will likely be better for...

    [Advice Needed] XHP70 12v vs 6v and Dive Light Design

    Hi all, been lurking for a while and decided to build my own light now and looking for advice on a few things and help finding potential parts. First off the goal is a dive light with an XHP70 @ 3A+ with a 4s 14.8V LiPo 10aH pack for ~4 hours of burn time. Question #1: Can someone confirm my...
