Eveready 7W Led Light Bulb | High Efficiency & Glare-Free Light | Pack Of 12 | With Li-Ion Battery Inside | 7 Hours Battery Backup | Overcharge Protection| Cool Day Light (6500K) - B22D

It's quite bright. Suitable for places which require just enough brightness /light. Even good for leaving in whole night in compound.Smart & economical decision.

NA for this bulb as it has a PF of 0.9 but just an information to clear any confusion.[After a reviewer claimed that as this eveready LED has 0.5 PF and hence we will be charged double of the mentioned wattage but a couple other reviews contradicted him. Hence I googled this a bit and this is the best answer I got. Hope it helps others who were as confused as me !!“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.”]Ordered thus product for 274/- & 215/- for 7w & 5w respectively. This is my first experience with LED bulbs and following are me observationsPros:- Biggest plus is price factor. Cheapest amongst reputed brands.- 100 Lumens/watt is excellent. 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.- Cool day light gives a nice shade but don’t know if it is better or worse than other brands having same shade. But am happy with this.- B22 base hence no modifications required.- I was using 15w CFL and this 5w certainly gives equivalent brightness.7w a bit more.Cons:- On the site it is mentioned that it offers 30months warranty from packaging or 24 months from invoice date whichever is lower but there is no warranty card or any mention on the package. So I don’t know what to do if the bulb fails in warranty period. Amazon should clearly mention this in the product page. (One star reduction for that)VERDICT – 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.

excellent

Amazon, as usual, was quick in shipping and delivering the product to me in perfect condition.Pros:1. Power efficiency. It's a known fact that LEDs are more power efficient than CFLs. However, Eveready claims that it's LED lamps are the most efficient (100Lm/watt) when compared to the LED lamps from the competing brands. It's light output is comparable to 15W CFL. Perfectly suitable for small rooms like bathrooms.2. Direct drop-in replacement. The lamp has B22D base. So it directly plugs into existing bulb socket, no need to do any changes to the electrical setup.3. Reasonably priced. In fact, It was the cheapest (well known)branded 5W LED lamp on amazon at the time of writing this review.4. The product feels sturdy and durable.Cons: None. Have not used it much so far.Note: I looked at the product packaging box for information about where the product was manufactured. I could not find it. It's just mentioned that imported by Eveready. Most probably, it's a made in China product. It's still better than unknown brand products. I expect Eveready to have done strict quality control so that the product matches their quality standards and is worthy of being branded as Eveready. Also I'm sure, given better efficiency claims of Eveready, these are not just generic China LED bulbs branded as Eveready. I could not find warranty mentioned on the box.LED bulbs are a bit costlier compared to CFLs. However, given their low power consumption and long life, the cost is recovered. Above anything else, we should be doing our bit in reducing carbon footprint and environment pollution even if it means paying a bit more for the products we use. As LED lamps consume less power, last longer(less contribution to e-waste) and don't contain any toxic material, we all should start using these.

According to its lumen light is good but quality not in level.

Good quality , worth for price n handy useable items.

Try to call Eveready multiple time but not able to connect, within 15days product is fused. Company is giving 2years warranty but totally worthless for me. I recommend purchase product from shop rather than online

Let me start by saying that the lighting is good and I can't complain about the quality.You can use this one in a small bathroom or cupboard. It's definitely not bright enough for living rooms and other larger rooms (anything above 15x15 feet), and it's too bright for a night light.The main problem with this piece is that compared to other competitive pricing right now, these are set quite expensive. At first I thought I got a really good deal, but after looking around for a while I can only feel that it's quite expensive. The price can perhaps only be justified by brand value - which is something I'm personally not very fond of.
