> Experimental adult males were maintained in constant darkness (DD) or constant blue light (BL) with a peak emission of 460 nm produced by the MarsAqua Dimmable 165W LED Light with a photon flux density of 20–30 μmol/m2/sec (irradiance of ∼0.4 mW/cm2) measured at the level of horizontally placed narrow vials (Genesee Scientific), each containing 25 flies as previously described (Nash et al., 2019).
0.4 mW/cm^2 is 4 W/m^2.
If I understand the unit correctly, this is equivalent to sitting 50 cm away from a light source emitting ~12 Watt of blue light (50 cm radius results in a sphere of 3.14 square meters, 12 W / 3 m^2 = 4 W/m^2). Assuming a 40% efficiency, that would be a LED lamp rated at 20 W, and emitting only blue light.
