It is save energy. It is very efficient. I am using Surya bulb from many years and I think everyone knows about Surya led bulbs. It’s very cheap as compare to other companies. It’s intensity of light very glorious. In my view of if anybody does not use Surya led bulbs then they should be used. It is easy available at electric shop near by your home. One more important think is that its cost is very less as compare to other companies led bulb.
