Photon Flash Flare
From Warhammer 40k - Lexicanum
Photon Flash Flares[1a] are Grenades used by Space Marines, that emit blinding white light when they explode.[1b]
Description
They are said to flare like miniature suns and cause those hit by them to immediately clutch their eyes due to the light's brightness.[1b] The Grenades are particularly useful in close combat, as Space Marines are able to avoid being blinded by them.[1a]
