What owners report
Olight Arkfeld Pro
- ✓Genuine 365nm UV rather than the cheaper 395nm — useful for real detection work
- ✓Three light sources in one flat body: white, green laser and UV
- ✓Flat shape carries far better in a pocket than a tube light
- ✓AL6061-T6 body with stainless steel fittings and a good anodised finish
- ✓Owners report months between charges in normal use
- ✗No ZWB2 filter on the UV, so visible light leaks and washes out fluorescence
- ✗The UV is underpowered and only really works in a dark room
- ✗White output stayed at 1,300 lumens while the laser got upgraded instead
- ✗Some units shipped with turbo and strobe swapped — patched, not recalled
- ✗The rotary switch feels lower quality than the previous model's
