LED illuminators are more efficient and have a longer life than other types of illuminators and bulbs. Depending on the application, it can last up to 20-30 years. Unlike compact energy-saving lamps, LEDs are stable and have no flicker. The increase in the number of turns and turns on will not reduce its service life.
The downside of LED lights is that the light is blue and light, making it feel cold, especially when compared to incandescent lamps. Other defects include direct light, which is suitable for use as a spotlight, but not for desk lamps. And LEDs are expensive and not readily available in regular stores.
But all of the above will be fundamentally changed. Under the advocacy of the US federal government to improve lighting efficiency, consumer lighting companies began to produce LED bulbs, equipped with a familiar base for diffuse reflection. The current LED bulb production is still low, but the quality is quite good.
The Lighting Science Group in Florida provides EcoSmart LED bulbs for Home Depot, a US chain. Even if the bulb inventor Thomas Edison reincarnate, I don't know the EcoSmart bulbs: the EcoSmart bulbs are wing-shaped, the fins are radiators, the top is flat, and the light source is scattered.
In the past year, lighting manufacturers have introduced LED bulbs that are close to traditional light bulbs. Although they cannot emit light from all directions like the current technology, they can disperse the light source well, that is, the user can be on the roof. Use this LED bulb.
The key is that the price of LED bulbs has dropped, and the price of LED bulbs equivalent to 40 watts produced by Lighting Science Group is below $20. At the end of this month, you can buy online or through the Home Depot chain, and you can also buy LED bulbs from other companies.
Brightness, energy consumption and money comparison:
A comparison was made by installing the EcoSmart A19. The conclusion is that the LED bulb is white and does not glow yellow like a compact energy saving lamp. The EcoSmart A19 is rated at 8.6 watts and has an actual power consumption of 6 watts. The brightness is equivalent to 40 watts of ordinary bulb brightness. The actual energy consumption of a compact energy-saving lamp at the same power rating is 9-13 watts. However, the A19 output brightness is 429 lumens, and the brightness is not enough.
Lighting Science Group CEO Zachary Gibler said that in the first quarter of next year, the company will introduce LED bulbs with a brightness equivalent to 60 watts of ordinary bulbs, which will have a brightness of 800 lumens and an actual power consumption of only 9 watts. Other lighting companies are also actively introducing LED bulbs, and Sylvania, Phillips, General Electric, Lemnis Lighting, etc. all plan to introduce LED bulbs with a brightness equivalent to 60 watts of ordinary bulbs.
The price of LED bulbs has not yet been determined, but Gibble said that LED bulbs with a brightness equivalent to 60 watts of ordinary bulbs cost about $35. Over time, the electricity saved is quite objective, but for one illumination. In terms of light bulbs, this price is still too high. Gibble said: "We will eventually match the new technology with the lighting output and quality, and replace the current halogen bulbs and incandescent lamps with user-friendly LED bulbs, highlighting the attractiveness of LED bulbs."
LED bulbs have their own unique advantages in some situations, such as lighting and where it is not easy to replace the bulb. Even if the price of LED is high, installing a long-life LED bulb in the above-mentioned places is of great significance to most people. As manufacturers continue to improve their technology, the price of LED bulbs will eventually fall, just like chips, tablets and other high-tech products, and their prices will gradually decline over time.
Gibble expects the price of LED bulbs equivalent to 60 watts of ordinary bulbs to fall to less than $10 in two years. The preferential policies provided by the public utilities sector will make the price drop even more, making the LED bulbs more popular. In the future, it will be more than just lumens per watt, but lumens per dollar per watt.
Cognitive lumens
Consumers should pay attention to the praise of LED bulbs. Last Wednesday, the US Federal Trade Commission (FTC) sued LED manufacturers, American Lighting, claiming that the company exaggerated its LED bulb output and life expectancy. The US Department of Energy will develop a detailed plan later this year with a number of retailers and certification companies to help users learn about new lighting technologies.
James Brodrick, head of the lighting program at the Department of Energy, said: "We want consumers to use new high-tech terminology when buying lighting products. LED bulbs are no longer rated by rated power tiles. It is expressed in lumens per watt showing color temperature and efficiency. Under normal circumstances, if the brightness is less than 800 lumens, it cannot be called the brightness equivalent to a 60-watt ordinary bulb.
