According to Wikepedia... At 42.3 billion candela/lumen. the Luxor Sky Beam is the strongest beam of light in the world. I can certainly attest to its strength in Aerofly FS 2. When I tried to fly through the beam of light I bounced off it and crashed.:p It seems to be a solid object. On a similar note, the fountain at Caesars apparently uses heavy water. Very heavy lol.
