I operate a LepiLED maxi (see Dr. Brehm’s website for the low down…); have used it for overseas mothing (e.g. the attached photo taken in Sept 2019, Dalma Wildlife Sanctury, Jharkhand, India, observations on iNat)
and taken the powerpack (x2) on international flights in the hand luggage. The LED unit is encased in a short plexiglass tube and runs hot (just over hand hot, so pack a cloth for handling / packing). I run it in conjunction with the Bioquip mothing sheet (fluoresces under uv light) and loop in the light unit on an S hook into one of the guy ropes for the sheet, so don’t need a tripod or other hanging point for the light.
Doesn’t seem to work well in areas impacted with light pollution (e.g. here in Hong Kong), but is good in more rural settings and great when well away from human habitation. The whole kit (light+powerpack+sheet) weighs less than 4lbs (probably less than 3) and can be operational within a few minutes once at the field site.
The LepiLED maxi operates for about 6 hours (plugging directly into a USB port) on a 26,800mAh powerpack (=99.2Wh) - the max size allowed in hand luggage on international flights
Once my mercury vapour lights are all cooked and buried, LED lights will be the way to go, I suspect. Definitely better than lugging around a large bucket trap, gennie, cable and smoking hot mv bulbs from a logistical perspective, though not a match for the mv setup in areas with light pollution.
