Answer Posted / sudhakar g
Surely 50 Bulbs are give more illumination....According the
size of the room we can take the Illumination levels of the
lamps.....suppose in a room we can take CFL lamps of 3 nos
the lumens that can carry more than the lumens that carry
2nos .....calculate the room leght x width ....then it will
come in SQ MTRS and find the lumens of the Lamps we are
going to fix...convert those in to SQ FT by using
10.76...then we can get the Lux per foot....
