CFL or LED

[GregS]

Now that we are on topic, I want to know what the best light for attracting stink bugs is.
I want to make traps. I will get rich ?? I read they might be attracted to yellow,
but that might not make sense.

This locality certainly has a mounting yearly problem.
A CFL should work fine, but I would like to compact it.
This is mostly for indoor use right now. Next summer its WAR.

I had to come on here. A while ago I was walking around my desk and started to
smell a stink ug. I say did one hit me? I sit down a feel something crawling inside my shirt.
I got the bugger out, but I stink !

I would have thought blue or UV - that's what's used in electrical traps

I'll try my Bug buster tonight. It has a UV light.
LED's are fairly narrow banded.

Step 1: Stink bugs.
Step 2: ???
Step 3: Profit!!

Sounds like Obama's recovery plan. ;-P

Cheers!

I did a lot of experimentation many years ago with homebrew bug
zappers.

My results: Blue / bluish, but also daylight-like with at least
some fair amount of spectral content everywhere from 350-375 nm range
through yellow-green, in my experience attracted most flying insects the
best. (Not much testing on stinkbugs, however.)

Also, in my experience smoothing of 50/60/100/120 Hz flicker helps a
lot.

For a good spectrum, I would suggest a 6500K CFL, modified to have a
bigger filter capacitor (with suitable life and temperature and ripple
current rating) rather than an LED, since 6500 K CFLs have a half-decent
spectrum.

Better still would be an "old tech" "Daylight" or blue fluorescent.
These produce more UV than medium and high color temp. CFLs do, since
medium and high color temp. triphosphor fluorescents tend to have a
UV-utilizing blue-glowing phosphor component, sometimes also a
bluish-green-glowing UV-utilizing phosphor component (the one in GE
"Reveal" CFLs, which have low color temperature).

The old tech blue is at least mostly only available in 20 and 40 watt
T12 (1.5 inch diameter) last time I checked. Maybe reptile cage
fluorescents from pet supply places... Use a suitable electronic ballast
to minimize 50/60/100/120 Hz flicker.

White LEDs generally have a spectrum that is lower on violet and UV
wavelengths than even 6500K CFLs have. However, I have yet to compare
those to fluorescents for attracting flying insects.
