From 2004 to 2015, advances in commercial lighting led to a huge installation of CFL based downlighters and also CFL Based 2x2 Grid Luminaires, that offered decent lumen output to price advantage. This has resulted in a huge installed base of fixtures incorporating 18W 2pin PLC CFL Lamps, 18W 4 pin PLC CFL Lamps and 36W 4pin PLL CFL Lamps. But these lamps had a typical life of 10,000 hours and would require replacement every 1.5 to 2 years on average.
Upgrade your PL CFLs to LEDs and become a contributor to greener environment.
As we approach 2020, with the advent of energy efficient LEDs and gradual shift to green buildings; retrofit LED alternatives are now available to the fluorescent light sources, which are getting obsolete. This is especially true for 18W 2pin/4pin PLC CFLs and also for 36W 4pin PLL CFL Lamps, where availability is becoming challenging.
Introducing, Osram 10W LED PL Lamp, that fits in exactly the same downlighter/connector as an 18W PLC CFL Lamp. It offers the same level of light output but uses only half the power of the PL lamps. This PL LED Lamp life span is 15,000 hours, and comes with 2 years replacement warranty and its priced in the range of Rs 250/-, which will keep falling down as its usage/demand increases. And a major problem it will solve is the huge downlighter installed base, where it can be fitted against defective 18W PLC Lamps. If the downlighter uses magnetic/copper ballasts, then just replace the PLC Lamp with the LED and no wiring change is required. For Downlighters with electronic ballasts, the ballast wiring needs to be cut, so that the LED Lamp can be powered directly by 220V AC Mains.
