wipro 7W e27 LED Warm White/Golden Yellow Bulb, Pack of 2, (N71002)

Ordered thIs product for 261/-. This is my second experience with LED bulbs after ordering 2 LEDs of eveready couple of months back and following are me observationsProsBiggest plus I can notice is that unlike eveready this brand provides some information if the bulb fails in warranty period of 2 years. See product description for a toll free numberWipro is a good brand. Light is bright enough and is sufficient.In a small room there is no observable difference between 7w & 5w but in a bigger room one can notice the extra 2w.So go for 7w if the room is bigger.Cool day light gives a nice shade and should be used in a room where you require bright light for reading..B22 base hence no modifications required.7w is as good as a 15w CFL. In fact a little brighter.Made of plastic hence no breakage tensions.Cons:None noticed so far.LEDs are the future. They are getting cheaper. They last longer, more power efficient. Time to replace the CFLs.PS – Attaching a few pictures of markings.THIS BULB HAS NO MENTION OF A PF IN THE DESCRIPTION. KEEP READING IN CASE YOU WANT TO KNOW HOW PF AFFECTS THE ELECTRICITY METER READING“Power factor is the ratio between real power and apparent power. Real power is how much power the load is actually using and apparent power is the product of how much current is flowing and the Voltage. Real power is measured in Watts, and apparent power is measured in Volt Amps (VA). If you think back to when you learned about electricity fundamentals, you might remember that current (Amps) times Voltage equals Watts. This is true for a direct current system and it is also true for an alternating current system with a power factor of 1.0. An old fashioned incandescent light bulb, due to being a purely resistive load, has a power factor of 1.0. However, many electrical devices including LED and CFL light bulbs have power factors less than 1.0. What this means is that while they might be rated at 13 Watts real power, they will draw more current than you would suspect. Assuming a 120V system, 13 Watts should require approximately .11 Amps (120V*.11A = ~13W). In reality, a typical LED light bulb has a power factor of .6 (and as low as .2 or less!). This means that the apparent power of the bulb is more like ~22VA (13Watt/.6 power factor). Remembering that apparent power is current * volts you can find that with a .6 power factor this bulb is using ~.18 Amps.The good news is that residential power meters typically measure real power and not apparent power…for now. This means that you are charged by the kWh and not Volt Amp hour. However, utilities are now beginning to install “smart meters” that are capable of measuring your home’s overall power factor (the average power factor of all connected loads) and charging you accordingly. For now, it seems like you are in the clear and you can trust the numbers printed on your bulb’s packaging.”

Excellent light, brightness and color tone of the unit, very bad after sales service. Out of 2 units purchased, 1 failed within a couple of months. The defective unit was replaced (home delivered) by Wipro ONLY after repeated complaints and escalations over a 3 month period. The replaced unit has also failed and have complained again to Wipro. Waiting for response and action from the past 3 months despite repeated reminders.

These lights are really good quality material. They are bright and light up the space very well.

This product was bought on 15 May 2018 and it has stopped working on 5 October 2019. It hasn't worked for even one and half years while LED bulbs are supposed to last much longer. There is no way to replace this product via amazon too.

It has a years warranty, however in less than five months the bulbs stopped working.

good product

The blub works fine. However the packaging is bad and three are scratches on them. So am not sure if these are new bulbs

Supposed to last long. Been only a few months and three of bulbs have fused. Quality doesn't come cheap.
