I have purchased a surya led bulb of 9 watts for my study room but when I switch it on it doesn’t have enough light.I am unable to study in the light of this bulb then a realize that I should have purchased any other company’s led bulb that why I have purchased crompton led bulb which is more lighter and brighter than surya led bulb.The cost of both the led bulbs is same so, why should I purchase surya led bulb and crompton led is more reliable and good in quality I will never purchase surya led bulb.
