Frequently asked questions

Start with the laser finder. Answer three questions about how you'll use it, the color you want, and your budget, and it ranks every laser we sell. The same page compares our Pens, Core, Valkyrie, Valkyrie Pro, and Max & Demon series side by side.

They're versions of the same laser with different output. The Output line on each product page lists the number for each version, and you choose the one you want on the product page.

The human eye is most sensitive to green and yellow-green light, around 555nm. That's why green and lime beams look brighter than violet, blue, or red beams at the same output.

Valkyrie, our flagship, has a polished 304 stainless steel body. Valkyrie Pro uses a polished bronze alloy body, chosen for better heat transfer.

Glow vials are an optional add-on for Valkyrie. They fit into the cutouts near the top of the stainless steel body and glow after being charged with UV or visible light.

Yes. Shipping is free on every order, and it's carbon-neutral.

Batteries can only be shipped by UPS, so any order that includes batteries ships by UPS. In some cases this can add time to delivery.

Some lasers ship in batches. When one does, its product page shows the expected ship window.

Each product page lists them under Power Source, for example 2x16340 or 1x18650. If batteries come with a laser, its page says so. You'll find compatible cells on our Batteries page.

Use a charger made for your battery type, don't leave batteries charging unattended, and stop using any cell that is damaged, swollen, or gets hot. Our Battery & Charging Safety page has the full list.

Wear safety glasses rated for your laser's wavelength, especially with higher-output lasers, and never look into the beam or its reflections. Read our laser warnings before first use.

No. Aiming a laser at an aircraft is a federal crime under 18 U.S.C. § 39A, with penalties of up to 5 years in prison and a $250,000 fine. Never point a laser at people, animals, vehicles, or aircraft.

Laser laws vary by country, state, and city. Check the rules where you live before you buy or use a laser.
