Holiday laser light projectors

Wondering if any of you have used these. They sell them pretty cheap on Amazon. I'm thinking they would be safe to use as the lasers that power them defract into hundrdeds of smaller lights. Unless someone takes it apart and looks into the main lasers running them.
Sure would beat stringing lights, climbing ladders all that
Thanks

I'm seeing a lot of commercials for these as an alternative to incan / LED exterior holiday lights. IMO, the laser diffractors aren't a match for a proper 'Clark Griswald' lighting job, but IMO, they might work under the right conditions. Those conditions being, (1) you have a white house, (2) you have half a dozen projectors or more because that's what the commercials show(3) you live on a dark street with no other brightly lit houses because nobody will notice yours.
You also need to use the outside rated unit because the common DJ projectors can't handle running for long indoors, let alone outdoors in the elements.

These guys seem to have figured out you need brighter diodes to make this work. Laser Christmas Lights and Outdoor Laser Lights | Light'em Up Lasers

Then there's already reports like this: Laser light reported by pilot discovered: Christmas lights | Fox17

At my work we sell the bliss lights along with normal holiday lighting. I have to say they are pretty cool. Covers 50' x 50' @ 20' away and I think the cover even more. The green is a single laser and red is dual. I'm going to be bringing one home to play with soon.

Wal-Mart near me has stacks of them, they are 39.99, I even saw then at home depot or lowes the other day, they should have a little 80-10mw 660 and a 30-50nm 532, but they are not worth 40 bucks to me.

The diffraction gratings are doubled up and turning, so even if the 532 had some ir leakage I doubt they could hurt you.

I wish ours were that cheap, I'd pickup a couple for sure! Ours retail for about 175 with our cost being about 110. I don't know how to find out the output. I'll see if it lists a class.

The link I gave is to a site that sells versions with 100mW greens and higher powered blues. I simply can't find anything remarkeable about the common 30mW green versions other than every other cheap bar in North America uses them as disco lights. I often see them in nurseries projecting on the ceiling to keep infants distracted. Over priced is an understatement.

Anyone else think someone is gonna do something stupid with this? I see ads on TV for it. Like someone thinking they can make it better with a magnifying glass and they hit their eye?

A magnifying glass will cause the "beamlets" to diverge and render the output more safe. These devices are mostly harmless.
