I found those cheap laser modules on ebay:


But they don’t look like laser diodes. My question is: Are they really lasers or are they just led focused into a dot?

They are laser's but yes they don't have a typical diode. They are built like the Dollar Store cat pointers but better built and will last a good long time.
I bought a 5 pack for maby $2 tops a while ago so these are very over priced..
They are not very bright for a red but like Anthony said they are fun to tinker with..

Ha, I bought that many too. The are probably the least expensive laser you will ever find, as mentioned above, they don't have a constant current driver, but are such low power, they don't need one, apparently.

Yes, as everyone has already stated, these are real lasers, low powered, but real.
I put one of these in a cheap little flashlight host quite a few years ago, and it still lases just fine. Here is a link to my build. :)

^^^^^^^Talk about a unlimited duty cycle^^^^^^^:):)

You should see my ghetto build's of them:whistle:.. I got so tired of the Dollar store one's dying out after a couple days of cat play, "the small ones that also have a little light" and I can't get myself to throw them away because of the flashlight part still working and them being keys chains also and them piling up in my junk draw that I taped one of these you listed to a 2 AAA battery cradle with a small limit switch taped on it too.
Hasn't croaked yet:giggle:
Also want to add, these are the ONLY lasers that I will play with my cat with..

For sale $5000 or best offer!!

Hey Red, how long have you had that little red guy running?

Just a few months, but I expect it will last for many years.

Your 5mW red laser "art light" reminded me of Javalins "The Little Diode That Could" thread. I can't believe how long his has lasted, hopefully it's still going strong!

It had been running for 5 years, and that was almost a year ago.

Hopefully, you'll have that kind of longevity with yours. (y)

Low power diodes that are run at or below specification should last anywhere from 6 to 10 years when run continuously. Good luck.
