Maybe making X-ray emitters cheap enough to put in a flashlight isn't the best idea anyway.

Maybe not in a flashlight, but the scientific industry would be very pleased with them. Sterilize water and all surfaces in a second? Flash with 200nm light.

Handheld battery powered X-ray devices exist and are widely available. I used to work with those. In Germany you need a permit to operate them. https://www.thermofisher.com/order/catalog/product/de/en/XL2

What’s wrong with the current UV tubes? Sure, the smaller ones take about 5-10 W to get the job done, so maybe an LED version would be more efficient. If you’re using UV to keep a massive pool clean, then you’re obviously going to be need more of those bulbs, and they can add up to hundreds of watts quite easily. Is that really a big problem though? Having a pool isn’t cheap, so electricity spent on UV probably isn’t going to be your main concern. Making it cheaper is always welcome, but are UV tubes really that big of a problem?

I mean they aren't instant and have to be within a fairly short distance of the thing you want to sterilize in order to work because they are absorbed by the air. Something like a pool would be practically impossible as water also absorbs UV and a pool is too big to penetrate all the way through just from the sides or bottom. It only works for drinking water because you pass said water through a tube that must be fairly narrow.

Oh yeah and an X-ray could sterilize all the way through an object, not just the surface. Very useful for making things like microwave meals.

How about cheap enough to put in a fleshlight?

If you have a bone in your penis, you may not be fully human.

Otherwise, don't x-ray your penis.

X-rays use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film or digital media.

Good advice, but I put a Kleenex in my urethra for safekeeping and I'd love to track it down to get it out again.

Amateur. It's in the scrotum along with all the pee.

Next time you have to fart just squeeze your butt cheeks together real hard. It’ll pop right out.

You tell me. Your user name suggests some expertise.
