This is a very interesting little clip light with 3 LEDs, one for throw, on the end of the light:
A side LED for flood that is High CRI:
and a side LED that is Red, and appears to be 670nm. Im a Big Fan of Deep Red.
Here are some Opple 3 DUV tests:
There are 2 separate magnets. They are strong enough to hold the light to a fridge, either flat against the clip, or at a right angle, against the tailcap.
The light works on both AA and 14500. The driver uses fast PWM on all modes, it is not visible to the eye, nor to my phone camera.
The UI uses two buttons, side by side under the black rubber cover. The upper button, closest to the end of the head, will cycle the 3 leds. There is Last LED memory. This means if we turn off at Red, it will turn on at Red the next time. This is very good for Astronomy and other Red light uses, where turning on at a White mode is not desired.
The lower button, closest to the tailcap, will cycle the outputs. There are 3 main brightness levels, with last mode memory.
From off Hold the upper button for Moonlight or 2 Clic for Turbo, 2 Clic again goes to Strobes. Moon, Turbo, and Strobes are not memorized. Red Moonlight is 1.4 lm, Spot Moonlight is 1 lm, High CRI Flood Moon is 0.6 lm.
There is a battery status indicator light on the button cover, it shows green on a full charge with LiIon. No battery level light with AA. There is no built in charging.
The Clip works very well and holds securely, and it has a lanyard hole. Total carry weight w LiIon is 68 grams, which is much to my liking for small, lightweight lights. I have not tried to figure out how to open the light, and do not know if it is moddable.
The clip allows the light to be clipped to the front of a shirt for hands free forward illumination, or to the back of a shirt, to be used as a rear marker set to Red, when walking or biking. The Red mode has Fast and Slow Flashing modes that would be appropriate for a rear marker, plus SOS. There is Tactical Strobe on both White modes, plus SOS and 3 second beacon.
Im especially pleased by the Deep Red LED and the Last LED Memory. This could be a handy little light to keep in a car, loaded with heat resistant Eneloop, or Ultimate Lithium Primary for longest storage life.
This is a preproduction prototype that I received as a review sample. Thanks to Wurkkos Terry for the fun little light
