This one likely uses a liquid crystal lens that is an off-the-shelf component that costs around $30.
That’s a lot cheaper that trying to develop technology for a liquid lens. Plus this one should be more reliable since it is all electronic and there are no moving parts to wear out.
As a zoomie, we would want it to be more floody in flood mode and more throwy in spot mode.
Unlike cheap aspheric lights, this light should not lose any lumens when cycling between modes.
I suspect what the liquid crystal lens does is act as an aspheric lens in one setting and as a clear lens in the other setting, plus in between.
My guess is the “throw” mode is when the lens is clear. All the throw would be provided by the TIR lens under the liquid crystal. In “flood” mode, the lens shifts to aspheric and distorts the throwy beam outward producing a nice flood mode.
This light may be attractive for the novelty or maybe a nice beam shape and hopefully a very convenient zoom action, but the throw (202 kcd) of the 64mm diameter head is twice as low as a conventional aspheric zoomie or a reflector light with this diameter and led.
New tech comes with a price. It will cost less over time and with competition. Today’s innovations will be the norm in 5 years, with corresponding improvements.
huh, 3x18650, 139mm length, and 64mm head?! sounds.. interesting. and HOT for a sbt90. but i agree with Djozz, 900 meter throw is NOT tempting for $460, even if there is a patented cool tech involved. Unless it zoomes and makes the beam shape FLAWLESS the entire course of the shape change. that could have value.
