I’ve owned #5 before. It’s larger than SK68 and not as bright. I also prefer push/pull zoom rather than ring.
Just received this one:
It’s the floodiest AA zommie I’ve ever seen, the beam is more than twice wider than SK68. It’s a bit dimmer when focused. The lens optically seems to be similar to SK68. It’s larger an heavier than SK68. Not bad overall.
It’s Yupard light from Aliexpress nice little light that can be resistor mod for extra bump… I change the LEDs to XP-E2 on noctigon and switch the lens with 19”mm aspheric and now it out throw my SC03 significantly
the reflector are plastic so you can use thicker wires and no worry about shorting
