Philips 12W Emergency Bulb | Rechargeable Emergency Bulb for Power Cuts | Backup : 4hrs, Cool Day Light,Pack of 1

The Philips rechargeable bulb battery backup was tested for 2 hours stills continues it glows I think in full run it will give 4 hours battery backup sure any way it is Philips brand

Durable and sturdy, earlier the first one flickering hence required to be replaced, thanks to Amazon for easy return. Giving one star less as the brightness in emergency mode is quite low, but switch functionality is quite good and enery efficient as well.

Last long about 2 hours approx.

Have been using it for around one year. Very good product, no issues faced, gives 3-4 hours backup easily.

Good for small room. Fortunately or unfortunately there is no power cut for long time once I got the product, so cant tell how many hours it worked. But light will not be sufficient for big room for sure.

On dated 02/03/2025 I bought rechargeable Philips 12 w and 9 W bulbs. After 2 months 12 W bulbs not working goodDrains fast, Dim light, and flickerSo replace my bulbs

The inverter led bulbs doesn't come pre charged, so don't panic, if you tested for functioning without power supply after you unbox. It takes around 8-13 hrs for initial charge (that's what is recommended) to test the inverter function of these led bulbs. Lighting intensity will be roughly half, when running on battery. The bulb produces a lots of heat while on power supply/ charging simultaneously. I am not sure if this is the case with Philips inverter bulbs or inverter bulbs in general. I cannot comment on total backup time, but so far it works fine, as said don't expect too much while running on battery, it will be half of light intensity while working on battery. Still it serves the purpose. If you don't have huge power outages on regular basis and thus you didn't have inverter setup at home, still if you need a backup lighting during short term power outages, then these inverter bulbs will serve the purpose. I brought them as they serve the purpose, without investing on inverter. Also it is not mentioned about energy rating on these led bulbs, may be because it is attached to li ion battery, due to which it might not get BEE ratings. BEE should also add this type of led bulbs to their device list and give appropriate rating, so that as a consumer, we shall get benefits while shopping. Overall, these backup leds working fine as of now. I will buy another brands inverter leds next time to see if they offer better light intensity and less heat producing while on power supply. By the way, I have all the led bulbs at our home and most of them are either 5 or 3 star rating, thus saves me huge electricity bills. So my preference always goes to start rated devices while purchasing, as they significantly reduce power bills. I hope this review will help prospective buyers make a decision. Do write up your experiences here, if you brought other brands inverter leds , it will help others to learn about your experience.

Review after 1st load shedding-Has enough brightness while on electricity, brightness reduces while on battery power however that brightness is still good enough. Once recharged fully, tested the light for 3 hours and it worked perfectly, post that the electricity came. I am happy with this product!
