Joking aside, my experience is large suppliers like this can usually provide quotes on items they deal with regularly in hours to a day or two during their regular hours, and if they have to work directly with a manufacturer on a special order of something that requires a little bit of special effort, it’s usually not more than a week.
Being that its a Linear + Fet Driver, it should be more efficient with a high Vf LED correct?
The LH351D has a higher Vf than your typical Nichia so it shouldn’t heat up as much right at an equivalent output right?
Last but not least, does this light have a mechanical switch or an electronic switch?
If you define efficiency by led-watts/input-watts then a higher Vf would be better. However I would argue that the most important efficiency is lumens/watt-input and in that scenario you want the LED with the most lumens/amp where the VF doesn’t matter as long as it’s low enough for the circuit to work.
I could have shaved another few millimetres off the length of the light but wanted a decently thick copper heatsink, magnetic tail and tritium vial in the momemtary switch button, still managed to keep it below 100mm.
This one’s a keeper, I never know how to price these things, by the hour + materials?
My time varies between £30-£50 an hr for work so if I said £30 x 12 = £360 + £40 + a niche skill set & unqiue item?….
That’s really nice. It may even be closer to the original spirit of the FW3A than the real thing. I’m curious though… did you flash the driver or use it stock? There are builds of Anduril for that driver if you want one.
Thanks. I used what I had on hand - a stock Emisar D4 driver with the switchwire connected to a brass ring sitting on the spring side, insulated of course.
