wipro 9-Watt B22 WiFi Smart LED Bulb with Music Sync (16 Million Colours + Warm White/Neutral White/White) (Compatible with Amazon Alexa and Google Assistant), Standard (NS9400)(Pack of 1)

Product Overview

Pros and Cons

Key Features Explained

16 Million Colour Palette & Dimmability

Wipro’s B22 bulb packs an RGB‑plus‑white LED array that can render roughly 16 million distinct shades. In Indian homes, where festivals like Diwali demand vivid reds and golds, this range is a genuine advantage. The dimming curve spans 10 % to 100 % brightness, meaning you can keep the bulb on overnight at a soft 10 % to save energy while still having a gentle night‑light. The trade‑off is a lower peak lumen output – about 800 lumens – which is fine for bedrooms or study rooms but may fall short in a 20 ft living‑room with high ceiling.

Music Sync Capability

The built‑in microphone picks up ambient sound and translates rhythm into colour bursts. For Indian users who love Bollywood dance parties in compact apartments, this feature adds a visual punch without extra hardware. However, the sync works best with music played at moderate volume; blasting speakers can overload the mic and cause erratic colour jumps.

Voice Assistant Integration

Compatibility with Amazon Alexa and Google Assistant means you can say, “Hey Google, set the bedroom light to warm white,” and the bulb obeys instantly. In a country where many households still rely on power‑cut generators, voice control can be a lifesaver – you can switch the bulb off before a load‑shedding event to avoid flicker. The only limitation is that the bulb needs a stable Wi‑Fi connection; during monsoon‑season outages, you’ll revert to manual control via the app or the physical switch.

Energy Efficiency & Indian Power Grid

Running at 9 W on a 230 V/50 Hz supply, the bulb draws roughly 0.04 A, translating to an annual saving of about ₹150‑₹200 compared to a 60 W incandescent. The LM80‑tested LED chips are rated for 25,000 hours, which aligns well with the frequent power‑fluctuations typical in many Indian cities. Still, the bulb does not have a built‑in surge protector, so pairing it with a good quality plug‑in stabiliser is advisable.

Performance in Real-World Use

Setting up the Wipro bulb is a straightforward three‑step process: screw it into a B22 socket, download the Wipro Next Smart app, and connect it to your Wi‑Fi. In our tests across Delhi, Bengaluru, and a humid coastal apartment in Chennai, the bulb paired within two minutes and remained stable for weeks. The build feels solid; the plastic housing is heat‑resistant enough to survive the Indian summer without warping. During a simulated load‑shedding scenario, the bulb retained its last colour state when power returned, which is a small but appreciated convenience. The only hiccup we observed was occasional app latency on a low‑end Redmi device, but the voice‑assistant path worked flawlessly.

How It Compares

If you need a budget‑friendly bulb with party‑grade music sync, the Wipro wins. Philips Hue offers a richer ecosystem and better integration with HomeKit, but its price is nearly triple. Syska sits in the middle on price but lacks music sync and has a smaller colour range.
