According to various research studies (ELCOMA, 2013; NITI Aayog, 2012; PwC, 2011), the contribution of lighting to the overall residential electricity use was estimated to be ~ 18-27%. As per a PwC study, in 2011, Indian households had an estimated one billion lighting points, wherein 46% points included CFLs, while 41% consists of tube lights. In addition, ~13% of the total lighting points comprised incandescent bulbs, with only 0.4% accounting for LED bulbs. Using a uniform annual use of 1,580 hours for each lighting point, the report further estimated that the overall electricity consumption from all these lighting points was ~27% of the total residential electricity consumption.
Although residential LEDs use ~75% less energy and last 25x longer than incandescent lighting, the high cost of LEDs poses a challenge to implement such energy-efficient lighting systems.
To enable this, the government launched the UJALA scheme to make energy-efficient household lighting systems affordable for all. Under the scheme, the cost of the LED bulbs—that were distributed through the state-run EESL—was lowered to Rs. 65 (~80 cents) in 2016 from Rs. 310 (~US$ 4.22) in 2013.
Moreover, to boost adoption of energy-efficient lighting methods/systems in the country, the government initiated numerous programmes such as DSM-based Efficient Lighting Programme (DELP) (2014) and the Bachat Lamp Yojana (BLY) to replace traditional bulbs with LED bulbs and reduce costs of LED bulbs to ensure energy-efficient lighting systems in every Indian household.
These government-led programmes also helped in creating awareness about energy-efficient LED bulbs; this bolstered the domestic LED market to expand from <5 million-unit sales per year in 2014 to ~669 million-unit sales in 2018 (as per ELCOMA India Report).
