Thanks for all the suggestions everyone !
For something relatively inexpensive that has both longwave UV as well as shortwave 254nm UV I found and ordered this:
UVTools LLC.
From what I researched the 254nm is what a majority of minerials that fluorcese need, but I am still considering later getting a mid-range UV LED flashlight as some minerials fluorcese under midwave UV (and some under longwave UV) even though most need shortwave UV.
.......and Bionic-Badger is very correct about the importance of safety when using shortwave, that is why I also ordered safety glasses specifically designed to also protect from UV-C (254nm) as well as UV-A and UV-B, many glasses only protect from UV-A and UV-B so make sure the ones you get cover UV-C also, here is what I ordered:
Elvex XTS Safety Glasses with Gray Frame and Clear Lens
(I found a 5% discount code for those safety glasses searching Google, I believe there are higher discount codes available for larger orders, but I can't vouch if they are valid since I only used the 5% one that was good on smaller orders)
Seems my astronomy hobby led me to Green lasers and a 405nm Violet laser also helped lead me to rock and minerial hunting
(405nm is just outside the longwave UV range but still close enough to cause some things to fluorcese)
I received my
UVTools 4W SW/LW lamp in the mail Monday Nov 22nd.
I've only had a chance to try it out a little bit so far, so this is a basic review.
First let me say this is a beginner's entry level lamp and not a model professional geologists might use, from my research it seems that shortwave UV lamps are very pricey because of the high cost of the special 254nm bandpass filter material that is used, and more powerful models can easily run from as much as $150 on up into the hundreds of dollars, so keep that in mind realizing this 4w model is about $35 which seems to be relatively cheap for shortwave UV, but 4w means the object needs to be fairly close to the lamp to be really effective, a trade-off for the low price.
They did include as a free bonus 3 small samples of material that fluoresces, a uranium marble, something that glows purple and retains the glow for a few seconds after the UV is turned off, and a small rock that glows a few different colors.
NOTE: make sure you are using relatively fresh batteries (4 AA size), I did not have any new AA on hand and the first set of used batteries I tried did not light the tubes even though it lighted the flashlight part, at first I thought I had a defective unit, but thought to try another set of used batteries I had sitting around and they had enough strength to light the tubes.
The batteries are a tight fit, I had to put the bottom 2 in first then the top 2 to make it easier to insert them.
The unit comes with 2 interchangable tubes, one for shortwave UV and one for longwave UV, PLEASE remember to be extra careful with the shortwave UV and always wear clear safety glasses specifically designed to also protect from UV-C (not all UV glasses protect from UV-C so make sure it specifically includes UV-C protection).
This is ok for a (relatively) low cost beginner's entry level model if you're not sure how serious you plan on getting into a hobby that uses it (like fluorescent rock and mineral hunting), just don't expect professional power for a beginner's price.
So far I am still glad I got it since I really did not have the spare funds in my "hobby budget" for a more powerful model right now, and even if I later get a more powerful model, this one could still come in handy as a very small portable unit to keep handy for when I might be traveling somewhere and might want to check any rocks or minerals.
The company told me in an email they do plan on getting some more powerful ones added to their web site at some point in time.
