1.7. The brightness of probably the brightest lamp so far available (PEK Labs type 107/109, excited by 100 W of electrical power) is about 95 W/cm² sr in its most intense green line (λ = 546 nm). Compare this brightness with that of a 1 W Argon laser (X= 514.5 nm), which can be assumed to be diffraction limited. 1.7.
