I recently purchased 9W wipro LED bulbs. Pair of Bulbs costed 215 rs in Amazon where in local shops it costs 230rs per pair.
Wipro Led bulbs are power effiecient. This bulbs has protections circuits against voltage fluctuations. Voltage variations will not affect the output if the bulb. This bulbs can work with low voltage also. After one hour of burning also this bulbs wont heatup much. Installation is easy like old tungston bulbs. It gives good bright light. I havent faced any issues with 9w bulbs while I do work with laptop, reading books under this light. For a small room this bulb can give is more than enough brightness. Its around 6 months I m using this bulbs till now no issue. Bulbs are reliable, one time investment gives less electricity bills every month.
