lumens's Usage Examples:

The same 1000 lumens, spread out over ten square metres, produces a dimmer illuminance of only 100 lux.

It is the ratio of luminous flux to power, measured in lumens per watt in the International System of Units (SI).

By comparison, a 60-watt household incandescent lamp will produce about 900 lumens.

most efficient commercially available LED lamps have efficiencies of 200 lumens per watt (Lm/W).

The luminous efficacy of a typical incandescent bulb for 120 V operation is 16 lumens per watt.

systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output.

The later 3LV model produced as much as 3500 lumens at a 250:1 contrast ratio.

to produce wavelengths proportional to human perception is measured in lumens.

small things, of which I have so many, and which I shall chain together prettily under the title Kleine Blumenstücke, much like one might name a series.

The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent.

allows the recognition of occlusion, stenosis, restenosis, thrombosis or aneurysmal enlargement of the coronary artery lumens; heart chamber size; heart muscle.

On a per-watt basis, incandescents produce 10 to 20 lumens, while fluorescents produce 50 to 100 lumens.

provides high levels of scotopic lumens allowing street lights with lower wattages and lower photopic lumens to replace existing street lights.
