Intelligence is not the pursuit of a light bulb, but practicality. A company called the finally light bulb has launched a new light bulb, which has no WiFi, no Bluetooth and uses sensing technology.

Since the war of smart home was ignited, there have been many ambitious enterprises or entrepreneurs trying to find better products to replace the incandescent bulbs on the ceiling. However, they all have some problems, such as the price of bulbs is too expensive, the product is difficult to realize, the review procedure is too long and so on.

Despite the obstacles, there are many successors. The company's founder is John goscha, who previously set up a company specializing in dry cleaning paint on whiteboards, but this time it seems to be determined to bring a small change to the ordinary living room.

Finally's bulb uses an innovative lighting technology based on induction. They call it "acandescence". Inside the bulb, an induction antenna reduced to 3 inches is wrapped in copper wire (rather than tungsten wire). This makes the bulb equivalent to a built-in magnetic field, which generates ultraviolet light through the pump and acts with the phosphor coated on the inner wall of the bulb, so as to produce visible light for illumination.

According to the company, the great advantage of the bulb is its warm and appropriate lighting quality, which is not weaker than LED lamps, but the price is not as shocking as LED lamps. Many consumers also don't like energy-saving lamps because the lighting effect is not satisfactory, and the price of LED lamps has soared to tens of dollars. Finally, the company's bulbs are 75% more efficient than ordinary incandescent lamps and have 15 times longer service life.

The company said the first 60 watt bulb will be sold in retail stores in July for $7.99. 75 watt and 100 watt bulbs will be sold in the fall. The company's manufacturing plant in India has been put into use, and the relevant review and supervision has been passed. It seems that everything is going well.

Many companies are developing towards high technology. The functions of smart bulbs are complex and diverse, but the products that are really suitable for people's home life should be practical and affordable. For the light bulb, the first function is lighting. How to make the light not irritate the eyes, and then develop other functions such as energy saving and communication. In today's practical lamps, CFL lamps are affordable and energy-saving, but the basic light quality is often criticized. Relatively good LED lamps are difficult to enter ordinary families because of their high price. It seems that finally's light bulb has reached a balance between the two. Maybe we can look forward to it a little more.
