Scotopic lumens can be defined as a type of light that is not generally detected by common light meters. It accounts for part of the human eyeÕs perception of brightness.
From 20,000 to 23,000 lumens depending on the brand.Average figures:Incandescent: 10 lumens per wattHalogen 13 lumens per wattCFL (low-energy) 50 lumens per watt
One lumen makes up 1 ANSI lumen as they both measure the same output of light. ANSI lumens are used exclusively for measuring the output of projectors.
This is roughly 500 lumens
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
A 150 watt halogen bulb will give off somewhere around 2000 lumens. These lights may give off up to about 2400 lumens.

Area can be used to find lumens. There are specific equations that are used to find lumens and area can be included in these equations. Plug the numbers into the equations and the amount of lumens will be found.
Currently maximum LED luminous efficiency is about 114 lumens/W, measured at 50mA. Average luminous efficiency is about 104 lumens/W. Ordinary LED light effect is about 60 lumens / W. 18W is about 130 lumens is about 1080 lumens.
Approximately 15 lumens per watt for halogen, so 300 lumens.
One lumen makes up 1 ANSI lumen as they both measure the same output of light. ANSI lumens are used exclusively for measuring the output of projectors.

With a profesional scotopic/photopic light meter. These cost $ 2,200.
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
