In the original article, there was an error. One of the inherent mathematical assumptions for Equation 3 as published, should be explicitly added to the mathematical formulation. The published terms “Vλ” and “Sλ” therefore have been replaced by “Vcλ” and “Scλ” respectively, to convey the implicit normalizations in the corrected equation. The term k has also been defined.

A correction has been made to Equation 3.

CLA2.0=1548{(∫McλEλdλ−arod1(∫Vλ′Eλdλ∫VcλEλdλ+g1∫ScλEλdλ)(1−e−∫Vλ′EλdλRodSat)) +(ab−y(∫ScλEλdλ−k∫VcλEλdλ)− arod2(∫Vλ′Eλdλ∫VcλEλdλ+g2∫ScλEλdλ) (1− e−∫Vλ′EλdλRodSat)),                                                                                                       b−y>0 (∫McλEλdλ−arod1(∫Vλ′Eλdλ∫VcλEλdλ+g1∫ScλEλdλ)(1−e−∫Vλ′EλdλRodSat)),     b−y≤0       

where,

b-y=∫ScλEλdλ-k∫VcλEλdλ
k = 0.2616 Eλ: light source spectral irradiance.
ab−y = 0.21 Mcλ: melanopsin sensitivity (corrected for crystalline lens spectral transmittance) (Wyszecki and Stiles, 1982)
arod1 = 2.30 Sλ: S-cone fundamental (Smith and Pokorny, 1975).
arod2 = 1.60 mpλ: macular pigment spectral transmittance (Snodderly et al., 1984).
g1 = 1.00 Vλ: photopic luminous efficiency function (Commission Internationale de l'Éclairage, 1994).
g2 = 0.16 V′λ: scotopic luminous efficiency function (Commission Internationale de l'Éclairage, 1994).

RodSat = 6.50 W m−2

Vcλ=(Vλmpλ)max(Vλmpλ) Scλ= (Sλmpλ)max(Sλmpλ)

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
