LED bulbs are now cheaper than CFL bulbs (or energy saver bulbs, as we called them), and their efficiency is increasing day by day. So, it's a no brainer to use LEDs to save the most energy (Joules) or money in our homes, offices and factories.
Do you know how much lumens of light you need for your room?
For household lighting, 15 lm/ft2 is more than enough.
For offices, use 30 lm/ft2.
For factories, use 50 lm/ft2.
For outdoor and street lighting, use 5 lm/ft2 is sufficient
Once you know the number of lumens you need, just divide that by the number of lumens a bulb or fixture provides, to understand how many bulbs or fixtures you need.
If you don't believe me, compare CFL vs LED, tubelights, halogen and other lighting options below. Just put in the square footage of your room, and we will let you know how many light fixtures you need, and the lifecycle costs. :)
