The lighting currently used for my tank is as follows.
3x 250watt Metal Halide Lamp(doubled ended bulb) with magnetic ballast,it's Kelvin rating is 20K-25K,made in Japanese lump maker. This light looks pale blue. This commercial reflector is used for the lighting of the outer wall of a building and magnetic ballast is standard type.
2x 250watt Metal Halide Lamps with magnetic ballast, it's Kelvin rating is 14K. This bulb was made in German. Light of this bulb looks pale,too.

3x 150watt Metal Halide Lamps with electrical ballast. This bulb is a screw formula type. A lens is a wide angle and has become half reflective mirror type. A mirror is designed to pass only required wavelength, UV and infrared rays also emit it back.
I use 2x blue light type and 1x red light type.

50watt & 75watt standard hallogen lamps made by 'USIO' are also used. Because of follows,with the lighting of only high kelvin rating metal halide lamps a tank looks blue too much and slight UV is required to get rich color of coral.

When metal hallide lamps tuned off at night, I use standard (not VHO) fluorescent light.
I used two type of fluorescent light bulbs, RB37 and BB450.
RB37 is fluorescent light which is 650nm-690nm peak enhanced and its light looks purple.
BB450 is fluorescent light which is 420nm-470nm peak enhanced amd its light looks deep blue.
There are two formula of bulb, straight type 20w-40w and ball type 27w.
I use 2x BB450 20watt,2x RB37 20watt,3x BB450 27w(pendant type reflector) and 1x RB37 27watt bulb.
