What wavelengths do you need? 350nm is starting to get into the dangerous end of the spectrum. Loads around in the 400+ nm range
Thats an interesting question David. I'm not entirely sure, except the blurb which came with the trap electrics & bulb said to avoid looking at the light, and minimise skin exposure when on.....
The other type of moth traps use mercury vapour bulbs, typically 125W and above, which again, emit UV light, as well as lots of white light in a neighbour annoying wattage (hence my opting for a actinic tube in my trap which I use in my back garden)
I'm certainly interested to see how you get on, as a LED based portable trap may be quite convenient if I ever try trapping in some local woods....
