Not very bright at all. A 40W light bulb is about 450 lm, so a 55 lm source would be about 1/8th as intense as a 40W bulb.

what is IS-LM?
lm; lm;
LM is a manufacturer's code--all LM chips were made by National Semiconductor. Similarly, SN chips were made by Texas Instruments.
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.
New LM was created in 1976.
LM stands for "Linear Monolithic"

Linear mode
The LM pilot is the person who pilots the Lunar Module, the mini-space ship that lands on the Moon. "LM" = Lunar Module.
