The or the heavily marketed BigLasers Gravitas 15W

sits at the absolute extreme upper end of consumer accessibility.

While consumer listings often boast massive wattage ratings (some sketchier sites claim 50,000mW or more), physics and legalities generally cap legitimate, accessible handheld laser diodes at around of true output. 🔎 Overview: The High-Power Handheld Market

is widely regarded among laser enthusiasts on specialized forums like Laser Pointer Forums as the gold standard for reliable, high-power handheld devices.

: It includes adjustable focus, a safety cap, and multiple working modes (high, low, and pulse/strobe).

: A 7W or 15W laser beam does not just blind you if it hits your eye directly; even the specular reflection (the glare from the dot on a white wall) can cause permanent, irreversible retinal damage in a fraction of a second.

: Blue lasers are the easiest and most cost-effective color to produce at ultra-high wattages. True 7W to 15W blue diodes are the peak of what is realistically achievable in a handheld form factor without carrying heavy external power supplies.

: It is heavily machined to act as a giant heat sink. However, because it generates massive amounts of heat, you are strictly limited to short "duty cycles" (e.g., 60 seconds on, 60 seconds off) to avoid frying the diode.
