683 lm/w for a pure monochromatic green light source at a single wavelength of 555 nm. This is because a lumen (lm) is measured according to sensitivity of the human eye and the eye is most sensitive at 555 nm. For a wide-spectrum "white" light source, the theoretical maximum is about 280 lm/W if the luminous energy is evenly spread across the visible spectrum. The number can vary slightly depending on the limits chosen for the visible spectrum and how white light is defined.
well i have no idea! sorry

the best light microscopes are limited to magnifications of 2000 times.

what is IS-LM?

Power magnifications are important in residential microscopes. Different magnifications on the market range from 40x, 10x and can be as high as 400x.

LM is a manufacturer's code--all LM chips were made by National Semiconductor. Similarly, SN chips were made by Texas Instruments.

New LM was created in 1976.
