Gulff Lampman
A true 365 nm torch built for fly tying: a flat lens and no zoom, fitted specifically to cut light loss, over a 3W Korean LED at the wavelength Gulff and independent tying suppliers identify as optimal for curing UV resin. Specs: 365 nm UV (UV output is the point — no white-light lumen rating); 18650 rechargeable, USB charging in the housing; no IP rating published. Gulff’s own warning stands behind the pick: common 395–405 nm lights deliver less energy where resin activates, and cheap UV lights’ advertised wattage is often a maximum, not a working figure.
