Inexpensive Blacklight Set-up

Nice. Do you take the reflector off the clamp light? I feel like it might be good to have the light itself as visible as possible. Also, what's your battery setup? Car battery?

Just wanted to let you know I have this setup running as I type this and it's great. I usually use a BioQuip light, but I didn't really want to ship one to New England or buy another, so I followed your advice and went to Home Depot. I have have it on a work lamp with the cage removed, just hanging in front of the sheet, plugged into a wall outlet, so not really worrying about power. I know a guy who really likes the Goal Zero power packs, which would work with an AC setup like this. The light is nowhere near as bright in the visible range as the BioQuip lights, but the moths seem to like it just fine. Anyway, thanks for the tips!

It could actually be as bright in the UV and we just can't see it. I'd love to see spectrometer readings on the two lights to compare. This post shows data for the Feit bulb. I've been using this observation field to track which insects I've attracted with a UV light, but maybe we should start tracking make/model of the bulb? Like "Attractant light make / model" or something?

Cool! Do you need an inverter to use it with the battery?

Neat...I've always wanted a moth trap or black light but never been able to afford it, and I've never met anyone who has had this setup. I might have to take a look into that. How do you stop the moths from circling around and leaving though? Do you have something for them to sit on other than the light itself?

Another quick question: are you able to take photographs at night or do you bring boxes for the good moths and keep them until morning?

I have the parts on order from Amazon (btw, I set up my Amazon Smile account to donate to Sequoia Audubon, and You Can Too!), and am eager to try this where I am currently cat-sitting in Palo Alto. Bug lamp, here we come. But I am interested in you and @kueda are using the same observation field, and if I should too once this arrives (and the Big Fun arrives with it)?

I use the field "Black/UV Light Attracted" and toggle it to yes. I remember to do it most of the time, but not always.

Ah, that's too bad. I'm sure they have similar bulbs at WalMart or other like stores. I actually saw some yesterday at a Halloween store.
I haven't tried it, but I wonder how well something like this would work. At 395nm the wavelength is decent.

Check out https://calnature.org/blog/2017/9/27/diy-moth-light. I've been using a setup like that alongside a BioQuip light this summer. My experience has been that these cheap LEDs work just fine. The potential downsides are that I don't think the lights are as bright (impossible to tell without something to measure the UV), and the narrow wavelength might mean they draw in less stuff, but IMO, the cost and portability outweigh both of those. I've been using https://www.amazon.com/gp/product/B073Y7LRRT, which are nice b/c you can attach them end to end, along with a Anker PowerCore 26800, which is a somewhat more expensive battery than Damon described, but has never run out of juice.

Looks like this might be the closest replacement to Damon's setup light right now:
