Technological advancement in all walks of life has made a deep impact on the concept of lighting as well - from the archaic concept of lighting with oil lamps to candle light and carbide gas lights, tulip lights, tube lights, chandeliers and twinklings.

About 5,000 people in Chandannagar alone and about 40,000 in the entire Hooghly district and its neighbourhood are engaged in some way or the other in this industry.

The craze for lighting is not restricted to puja pandals alone, as it enjoys pride of place at sporting events, corporate events and weddings as well, with costs ranging between Rs. 2,000 to five lakh or even more.

Multi-coloured tulip bulbs fitted on woven wire create a semblance of motion through lights, generating images of moving bicycles, rickshaws, cars, trains, animals, buds blossoming into flowers, fire-spitting dragons and such.

Innovations in creating images through lighting on contemporary events like Amartya Sen receiving the Nobel Prize, tennis ace Leander Paes making a serve, cricketer Sourav Ganguly driving a magnificent shot to regale onlookers.
