Ah, I see. I won’t deter anyone from seeking profits, but seems like they missed the market here. What do I know, I bet they sell enough. I gave away a trustfire z6 thats still in frequent use.
Moonlight on a LEP is fairly unique. Actually it’s listed at 8 lm, which isn’t exactly moonlight but is much lower than most if not all other low modes on LEPs.
That should give around 140m throw for the claimed 56 hours. I can’t think of one but I bet someone has a perfect use case for that.
They are not ‘white lasers’. They emit just like an LED. The only primary difference is that the phosphor is excited by a blue laser remotely rather than a blue LED. Due to thermal and optical limitations in traditional LED design, LEPs can achieve higher intensity (luminance) and therefore increased throw. Due to various factors including optic losses, lumen output is fairly low. Personally, I’m waiting to see a collar added to one. That could get interesting
They are much lower wattage than what most of us are used to on BLF. Max current draw is often under 3A and voltage around 4V. So 12W? That’s less than 1mm² Osrams. Long focal length convex optics likely only let out 50ish percent of the lumens on top of that. So all things considered, I think they do well. A recoil LEP is another idea that I think would be awesome.
Does wavien collar work for LEP setup? I hope it does as it could potentially double up the intensity which is crazy.
I am not sure, I think wavien collar works for LED is because the light source emits light in >100deg of direction, hence the collar is able to “recycle” those wasted light to the surrounding back into the die itself. But in the case of LEP what is the light emitting angle? I mean if the angle is already small, like <60deg (I really have no idea), how well could wavien collar “recycle” the light?
I see no reason that the emission would not be lambertian. And others have tested collars with LEP I recall with good results. Maybe not the 2x we’re used to but still significant. There’s some math behind it that seems like cheating physics but matches real world fairly closely. I’ll have to track that discussion down…
