ZWO LRGB filters are specially designed for deep space photography with monochrome cameras. 

The width of their bandpass is balanced with the spectral response of the ZWO cameras, starting with the ASI1600MM Pro. This results in the exposure time of each channel having a ratio of 1:1:1, meaning the exposure time in red is equal to the exposure time in green and in blue.

The L filter is an IR-UV cut filter for the luminance. 

The filters are parfocal so there is no need to refocus when the filter changes. The surfaces of the filters are optically polished and fully multi-coated. 

Each filter cuts off the ultraviolet and infrared violet so there is no need to use the L filter in combination with the colour filters.
