Should I Buy a 100mW or 200mW Green Laser Pointer?

by | Apr 8, 2022 | Green Lasers, Laser Pointers

If you’re shopping around for a green laser pointer, you have likely seen many different designs, output powers, safety features, and components. Green lasers can range in power from <5mW up to 1,000mW in handheld form. How do you know the right power level for what you want to do with the laser? Understanding the different power options is crucial to making sure you don’t go with a model that underperforms your expectations or is overkill for what you need.

What is Your Main Application for a Green Laser?

200mW green laser pointers are suitable for lots of different applications including astronomy, arborists, and more.

200mW Green Laser Pointer

What exactly are you trying to do with the laser? Lasers can be used for many different purposes and are a useful tool for many people. Green lasers are regularly used for:

  • Astronomy and Stargazing
  • Presentations
  • Burning Laser Experiments
  • Arborist and Landscaping Use
  • Construction Crews
  • Fire Rescue Teams
  • Law Enforcement
  • Armed Forces
  • Photography 
  • Scientific Research
  • Goose Control / Pest Control
  • Target Practice & Riflery

But these applications require different output power levels. A 30mW green laser that is great for astronomy at night will not be suitable for a burning experiment or goose control. Neither will a 100mW. Outdoor goose control in the flush sun, for example, requires a minimum of 500mW in 532nm green laser light to work properly. Go with a 200mW and the geese will not flee unless it is nighttime. But a 200mW is ideal for an arborist who needs to point out limbs of a tree that need to be removed, or a warehouse facility where workers can point to high shelves.

Knowing what each power level can do can be confusing. Let’s go over the basics.

Understanding Green Laser Light Output Powers

Breaking down the powers will help you understand which unit will be your best option. Take a look at what each range can do. (This is a short-list, the suitable applications are greater so use this as a guideline)

  • 5mW – 15mW Green: great for presentations and indoor classroom settings, basic astronomy, small-scale photography. Not suitable for outdoor daytime use.
  • 50mW – 100mW: great for nighttime astronomy, large auditorium presentations, warehouse work (freight & supply chains), photography. Not suitable for outdoor daytime use.
  • 200mW – 300mW: astronomy, warehouse work, landscapers and arborist crews, fire rescue teams, riflery. Outdoor daytime range of 50 – 100 feet maximum.
  • 400 – 500mW: burning laser (light matches, pop balloons, cut electrical tape, etc), the starting point for goose control, long-distance night signaling, military exercises, longer-range riflery (100m scope zeroing). Visible for 15 – 20 miles at night. Outdoor daytime use of 100 -300 feet.
  • 500mW – 1,000mWbest for burning, best for daytime goose control and other pest control, riflery at 300m+, visible for over 20+ miles at night. Outdoor daytime use 300 – 1000 feet. The strongest available for civilian use is 1,000mW in green.

Now that you have an idea of what the various green laser outputs can accomplish, you can start to narrow down the designs you’re considering.
