Very interesting. Very curious how it works. In the flood mode it sort of looks like a diffuser is being used because it looks like there is a lot of light being scattered at wide angles.
A typical aspheric actually loses more like 70% of the light when in throw mode.
So how much output loss is there with this zoom and correct me if I’m wrong but doesn’t LED lenser already have this? or is that something different? Also does this mean it has more throw than a reflector or just a slightly larger hotspot at full zoom?
Well if it has no moving parts then it’s not “zooming”
I guess it uses a hybrid optic with several LEDs placed at different focal points, the focus change is controlled by shifting the current between the emitters.
Led lenser uses a special optic where the emitter travels inside and most of the light is captured by the optic at all focal settings, but it still requires moving the head to zoom.
LED lenser uses a movable TIR style reflector which has much better light collection efficiency than a simple aspheric lens. The head still moves in and out though, so the manker design is different.
It would not have more throw than a reflector since the throw is mostly determined by the size (frontal area) of the light.
There have been several similar “electronic zoom” lights which operate by transitioning between a throwy LED and a floody LED.
I am hoping that this version uses a TIR for the throwy optic and then has a COB ring LED mounted behind the TIR on the same MCPCB as the main LED. That has been my favorite combination.
Discussed on reddit , with a claim that there’s “no moving parts” and “only one LED”. I’m not sure how this could work if both of those statements are true.
That makes it sound like there’s an LCD between the optic and the front glass, which controls which parts of the beam leave the light. Or even just diffuses the output.
Smart glass that diffuses the beam?
Variable shape lens?
Both seem too expensive to be worthwhile so I guess it’s something different.
I’m mildly interested with such teasers.
Show us the tech and then we’ll be able to tell whether we like it.
BTW, I can’t see the vids. Neither on FF nor on Chromium.
