I have a couple older hand held Long Wave UV Lights but the bulbs are about shot.
Finding replacement bulbs is not easy and the few I find are expensive. Seems I can get a new hand held LV light for under $10.00.
But while looking for replacement bulbs, I kept getting results for small Long Wave UV flashlights.
So I was wondering if anyone has had any experience using these newer LW UV flashlights for their stamps and opinions on them.
edited to add: Or can anyone suggest a source for replacement LW bulbs 6 inch, 4 watt HF4T5/BLB I think is what is on the bulb.
Thanks,
Dave N.

I purchased a dual wave recently where the LW was on the end and was not impressed. The light pattern was similar to an old style bulb flashlight.

I bought a long wave LED flashlight. It's only about 6 inches in length, and didn't cost much. It works better than the one that Chris mentioned, which I also had.
You can find replacement bulbs on ebay. Also, check if you have a light bulb store in your area. Those bulbs were used in counterfeit currency detectors. With the revised currency, they are not used that much anymore, but you may be able to find them. The bulbs do not cost that much in the stores. They are over-priced if you go the " philatelic hobby" route. Perhaps Hobby Lobby might have them too. The weekly 40% off coupon would make the price even better. Search for what used to be called a "black light". It's basically the same thing as a long wave UV light.

My husband asked for one as a Christmas gift - the clerk at the store asked if it was going to be used to check for cat urine (uh no, will be used for geocaching). Apparently they have all kinds of uses.

I bought one, a 12 LED (the number LEDs)
395nm brightness (the key to it working)
I think any model will work as long as it is 395nm brightness
I've been looking for a CHEAP ONE for years and took delivery today!
It worked right out of the box
Here is a filtered selection meeing that criteria

The 395nm is the wavelength of the light emitted. Brightness in lamps is usually marketed in watts. Brightness is far more important in shortwave when trying to use these lamps under normal light. It is best to use in darkened area since the standard light dilutes the light from the lamp since the luminescence response can vary.

Since these are 395 lumens, they should be 4-5 watts
So as long as you select 395 nm it should work
Lumens for Light Source Watts:
375 Lumens = 4 LED Watts
450 Lumens = 6 LED Watts
