The light intensity of fluorescent tubes is also measured and rated on another standardized scale called lumens. |
I live in Flagstaff, AZ and the light pollution laws here limit the amount of lumens per acre. |
It comes with two lamps, one with 125 lumens output while the other offers 225 lumens. |
Fibrin and platelet thrombi were prominent in the lumina of the vessels and in the space beneath the endothelium. |
These loose columnals may have had soft matrix removed from the central lumina and, thus, would have been very bead-like in appearance. |
Some cells have intracytoplasmic lumina with hyaline globules, and there may be hemosiderin deposition. |
