Lambda logo, Half-Life Wiki
The Lambda logo (λ) is a symbol found frequently in the Half-Life universe. It represents the Greek letter "Λ" (lowercase "λ"), and is a radioactive decay constant used in the half-life equation. "Λ" is the 11th letter in the Greek alphabet. In the original Half-Life, Gordon Freeman's trademark HEV Suit was marked with a Lambda logo on the chest, as were other HEV Suits. A section of Black Mesa dedicated to teleportation research was also called the "Lambda Complex," and is identifiable by the L
