## Convert spectral energy irradiance into spectral photon irradiance

### Description

Convert spectral energy irradiance [W m-2 nm-1] into spectral photon irradiance expressed as number of photons [s-1 m-2 nm-1]

### Usage

    as_quantum(w.length, s.e.irrad)

### Arguments

`w.length` | numeric vector of wavelengths (nm).
`s.e.irrad` | numeric vector of spectral (energy) irradiance values.

### Value

A numeric vector of spectral photon irradiances.
