I happened to see this email, so I am going to get one of these from Lowe's and
make some measurements of it.
ARRL does have the capability of making measurements of noise levels, to see if
these devices meet the FCC rules, so it is best that we hear directly about
possible interference sources. Email rfi@arrl.org with info on noisy devices.

Subject: [RFI] Laser Christmas Lights
Beware- like most electronic junk allowed to be sold today, the new "laser
Christmas lights" that project various patterns on your neighbours decorated
house, are RFI buzz machines.
Mine (and the ones up and down the street) take care of killing most the HF
spectrum and includes some nice AM BC Band swaths of frequencies as well.
Mine and units were sold by Lowes , and have a plastic lens globe on the front
of the fixture, which is pointed towards the desired surface to make a pretty
pattern.
The "destructive" RFI range heard on my portable radio was + 40 feet. Seems
these lights are the new, popular effect this year and most folks may be
surrounded by installations.
Unfortunately, my antennas are also all within a 25 foot separation of the
neighbours, and the general increase in noise floor from the residential area
won't make for a Merry Christmas.
