I tried this at wurkkos.com for delivery to Canada but it didn’t work for the light with or without battery.
Unless you meant it will take 6 hours to become active.
Ordered the DL70 w/ coupon from other thread and extra 10 off today on amazon us. If it is as good as I expect, what an amazing deal for $67.
I’m very tempted by the wk30. Please make a headlamp the same way w/ 21700 or 18650! Acebeam is the only decent headlamp I can find w/ uv, red and white but it’s too heavy and $130. Everyone I camp (and especially fish) with would like a less heavy version w/ those three LEDs wavelengths.
