Brightest laser for daytime photography that is safe to not start a fire

I'm trying to photograph a line drawn with a laser during a dark overcast day. My basic understanding is that 555nm is brightest in daylight and 100mw+ is strong enough to start a fire. So, I want something that is less than 100mw. Am I on the right track? Is this simply not possible with this low of wattage? I would ideally want something that I can easily mount to a surface. Can you recommend any online stores to buy this from?

Should mention the distance the laser needs to cover is only about 20 yards.

Anything over 5mw can cause eye damage so remember there are other safety concerns besides inadvertently burning something with a laser that's not in your immediate control, also you can set up beam stops and use materials in your arrangements to absorb the beams without casting unwanted diffuse reflections.

Brucemir did a lot of fantastic laser art, take a look > https://laserpointerforums.com/search/924765/

Just get a laser line level, they draw a nice bright red line on most surfaces that can be seen during the day and photographed, plus they are relatively inexpensive to buy... ;)
