UV light for charging glow in the dark lures

Obviously I've been sniffing around the $1 units on ebay

But I'd be willing to spend a bit more on one that has the breammaster seal of approval.

Any suggestions welcome.

The highlighted sentence below has got me intrigued

Turns out you can even spot scorpions with them

So far I'm liking the idea of a very small torch that fits in your pocket - this fella with a Zoomable head is the right size and it runs off a AA

Can't comment on the price and quality of UV lights these days but i can tell you that they absolutely will make your glow products glow brighter and longer and worth the investment you have indicated. I purchased mine to set a product called "Knott Sense" but it doubled beautifly to highlight the glow on lures.

Correct frequency is important

If you want maximum effect from "black light" reactive items, 365nm is the proper wavelength for this.

The 400nm visible UV LED flashlights only appear brighter because they're illuminating the item with visible UV light, not because they're actually brighter.

A good UV flashlight will only activate fluorescent objects.
Also - standard UV LED torches and Flashlights in the 400nm range generally produce a strong 'UV beam' best suited to illuminate 'at a distance' and are not usually suited to close-up work owing to the higher visible-light 'interference' output, which tends to mask (or suffocate) the resulting fluorescence.

1. POOR QUALITY (Frequency Range: 395 - 405nm)
UV Torches operating in the wider 390nm - 405nm range generally use poor quality 'cheap' UV LEDs which produce far too much unwanted visible 'purple glare' (interference) and far too little in the way of a useful UV light.
A general rule-of-thumb is the more LEDs the torch has, the lower the Quality of UV produced.
Avoid torches with more than 9 UV LEDs.

2. GOOD QUALITY
(Frequency Range: 380 - 390nm)
Torches outputting UV in the 380nm range perform much better and produce superior results, with a much reduced 'visible' (interference) output.
Such units will naturally be more expensive than the cheaper 390nm models.

3. HIGH QUALITY (Frequency Range: 365 - 375nm)
By stark contrast, the higher quality, more expensive torches producing the 365nm wavelength, produce a near pure UV output which is the optimum frequency for UV fluorescence. This means you will see far more detail and in a greater range of colours than any other wavelength. As these units generate less unwanted Interference light, they may naturally appear weaker or darker. This can be misleading and should not be misinterpreted.
General rule of thumb is that the more visible UV light you see a worse quality it will be.
Lots of visible purple light is not an indicator of UV quality and indeed it is usually the opposite.

ATTENTION - CAUTION
Danger !
Eye damage guaranteed from careless use. These LEDs are manufactured to be almost invisible to the naked eye. It is made for a specific purpose and should not be used by children or people unauthorised by you the tradesman. Invisible UV is particularly dangerous to the human eye because it cannot detect that damage is being done.

Still, scientists don’t know what purpose the fluorescence serves. Some theories:

• It protects scorpions from sunlight.

• It helps them find each other.

• It might confuse their prey.

An article on the news website LiveScience reported another theory, by California State University arachnologist Carl Kloock. Because scorpions avoid sunlight in general and UV light in particular, he thinks the glow actually helps them figure out whether to come to the surface or stay underground, based on how much UV light shines on them. For example, these nocturnal creatures are less active on moonlit nights and during the full moon.

For humans, one benefit of the scorpion’s glow is that it makes these stingers easier to see in the dark. Which is perfect, whether you’re trying to study them … or avoid them!
