I don’t mean an automotive strobe light (tool). I mean something you use in your house/in a party, like this one
Have you ever owned one?
Yup. WAY back in the early 70s. Had a couple of blacklights, too.
Of course, standard kid equipment in late 70s/early 80s; as was the lava lamp & black lights & year-round Christmas lights. I was totally drug free until my late 40s. Just naturally trippy.
Got one from Target a couple years back for our front yard Halloween decor.
No, too many epileptic friends.
No, but I had a light switch and a really twitchy wrist. 
No, but I had a plasma globe!
I have one of those multi-function flash lights that has a strobe function for emergencies. Since that doesn’t meet the spirit of the OP, I voted no.
My company bought one for an exhibit prototype about 15 years ago. It’s still up on a shelf in the shop.
Yes–a skull one like this.
I still own it too.
I bought it for when I feel like dancing to “Mr Roboto”
Yep. We bring it out every week or two for the wee kids to dance to.
I own several different types of strobe light, including ones from Radio Shack and Spencer gifts that were bought in the 1970s and “professional” ones like the Martin Atomic.
I didn’t own one, but I had access to one. When I was stationed on Adak Island, I did airfield maintenance, so I had a spare approach strobe light in my shop. I used to schlep it up to a cabin where we had parties and let it rip. I once got a call from the airport tower asking me WTF was going on up on the hill. 
I also had a lava lamp. Hey, it was the 60s/early 70s.
Yes. Did I mention that a college roommate and I were both big fans of the B-52s?
Yes, back in the 60s and 70s. And I bought one a few years ago that was sold as a “strobe light” but was LEDs that turned on and off, with about equal times spent on and off. This was like a turn signal, and had absolutely no motion-stopping ability. It has since dawned on me how difficult it is to determine whether something sold as a “strobe light” actually has that stroboscopic effect. I think it has to be a xenon flash lamp strobe light – in spite of the fact that you could design an LED based light with stroboscopic effect. LEDs care about average power but tolerate it in brief extreme pulses quite well.
Made a few for myself and others back in the 70s. Neat little thing when you were ------ studying.
I’ve got a LED light bulb that almost immediately after being installed decided to flaunt that “lasts forever” business by turning itself on and off randomly. The toggles aren’t fast enough to be a strobe, but sometimes when it’s toggling it can’t decide what it wants to do and strobes for a second or two.
It’s a shining* testament to my laziness that I haven’t gotten rid of it.
*intermittently
Giggling way too hard at that.
I never owned a strobe, but I have an LED UV flashlight and I consider it probably the best material acquisition of my adult life.
