I would like to know what AFFORDABLE green laser can hit clouds and shut off streetlights best. Output power does not matter. Price range must be &0 - $50.

You have a few lasers in your current inventory that are capable of this.

Just to let you know, you have to hit the sensor just right for it to work.

Please don't try this on every streetlight in your neighborhood. You will draw unwanted attention to yourself and the hobby.

There are plenty of "constructive" ways to enjoy the technology.

so a 200mW red laser can shutoff streetlights and hit cluds? or a 5mW DX? O I also have a wicked lasers core can that? idk about a blu ray laser doing that o my 200mW green is broke

I have successfully projected a visible spot with 100mW of green, 60mW of green, and 200mW of red on low cloud cover. If the clouds are low enough and there is low light pollution, 5mW of green could even do the trick.

Higher clouds are a bit more difficult. I have done this with my >650mW green with a 10X beam expander but none of my other lasers are capable.

I was thinking of getting a PGL-III-C a while ago but it can hit clouds that are high up with an expander? That's impressive. Anyways I guess I'll never be able to hit clouds because I live in Phoenix, We're too low and there is alot of light pollution. Not only that we never get fog :(

I was wondering if the 15 dollar 50mW focalprice laser can hit clouds good because the beam never expands?

There are advantages and disadvantages of living in a very dry area like Phoenix AZ. On one hand, the dry air reduces the overall city light pollution a bit and offer a nice starry sky, but on the other hand, clouds will reflect all tht light and since the air is very dry, not much of a beam can be produced even with higher power lasers, unless there is a bit of wind kicking-up dust. You do need a laser with a very visible wavelenght, like a greenie, with a fairly powerful output.

Your broken 200mW grenie would have been adequate for this purpose. What's wrong with it? Have you tried having it repaired or checked-out by someone? Maybe one of the elders of the mighty LPF could have a look at it to see if it can be revived. :)

And as mentioned by the people above, tripping off streetlights is pretty pointless and might attract unwanted attention, and be careful when pointing at clouds, there might be planes hidden by the cloud cover so be patient and look at the sky and listen carefully to make sure there are no aircrafts in the vicinity when you fire-up your laser.

The diode overloaded I used 4.2 volts instead of 3 :p
