The new concept of GE playing, whether the "HD lamp" is what?

Many people can not help but ask the title: what is the definition of a light bulb? In fact, the so-called high-definition light bulb is released by Ge Corp LED new light bulb, which contains a variety of sizes, various shapes, a variety of power and a variety of color bulbs. The so-called HD bulb is not what we usually understand HD concept, but Ge Corp want to convey the idea of excellent lighting quality here.

But there are some models of light bulbs do have a strong color rendering capability, but there are some models in terms of brightness and dimming performance unsatisfactory.

These bulbs prices and specifications are more close to the people from the ordinary A bulb for $8 2 (about 55 yuan), therefore, the use of general electric bulb as the new high-definition home lighting is still relatively affordable, especially to improve the lighting environment in the home.

General Company offers three equivalent 60W standard lighting HD bulbs:

The first is the "Relax" LED light bulb, it can create a candle like warm light environment, so that the room can become warm at night.

The second is the "Refresh" LED light bulb, it can send out the color of the sun light, can be more focused on the day, energetic to complete the work.

The last one called "Reveal" LED bulbs, which is a common brand for many years, so that the room has a better color quality, suitable for kitchen, living room and other places to install.

The following is the detailed parameters of these three HD bulbs:

The power of these three bulbs is only 10.5W, only 60W of ordinary incandescent bulbs of, if the average daily use of 3 hours, then the annual increase of about $7.20 (about $49) of ordinary incandescent electricity tariff. Under the same conditions, the use of these three types of light bulbs, the annual electricity expenditure is only $1.26 (about 9 yuan). This calculation, each bulb will save $5.94 per year (about 41 yuan), if a room is down every year can save a lot of electricity. The use of ordinary incandescent bulbs and the life of about 1 years, the general service life of HD bulb for 13.7 years, if the replacement lamp cost in the inside, each lamp in use period will save $81.38 (about 559 yuan).

However, these energy efficiency is not unique to General Company or any other LED lamp manufacturers. LED is inherently more efficient than other bulbs. If you have the existing incandescent bulbs or fluorescent light, will save a lot of money. However, to determine the true value of LED bulbs, but also to consider its performance factors.

The above picture shows the lighting effects of three high definition bulbs, all three LED bulbs provide a very strong color accuracy, but the best Reveal light, no excessive yellow.

The brightness of each section of the bulb is tested, although they are within the error range, but none of them is as high as the parameters described. For "Relax" and "Refresh" LED bulb is also good results, both brightness is close to 800 lumens, can be a perfect substitute for 60 watt ordinary light bulbs. However, the "Reveal" lumen is only 554, the product packaging box can be used as a substitute for a 60 watt light bulb, but it is more like a light bulb 40W light emitted by the lumen of the 450, or rather disappointed. This happens because the plastic bulb has a special filter to reduce some of the yellow light from the visible spectrum.

Can be seen in the above figure in the W shaped depression blocking light. The yellow hue barrier intermediate spectra, avoid the yellow light is too strong, in fact, it can make the light bulb in the home color is more rich and true, but this also means that the brightness of the bulb will be reduced.

There is a simple way, is to increase the power of the bulb to compensate for the loss of brightness, but General Company did not do so. It's good, but it's obviously not the right way to go on to replace the 60 watt bulb. General Company engineers said plans to use the next generation of Reveal bulbs to solve this shortcoming, they claim that the next generation will provide higher flow, while consuming less electricity, it is worth looking forward to.

However, as expected, the Reveal LED is very suitable for lighting in the test render vivid, accurate color and white, very clean, not as yellow as most soft white color light bulb. These changes are very subtle, if you are a perfectionist, very suitable for the purchase of this bulb. Although unlike Reveal LED bulbs that color reduction effect is good, but the actual test of Relax and Refresh LED lighting is also very good, although there will be additional yellow light, but they are rendering color, other than it looks comfortable lighting LED.

The last item of the test is the compatibility of the dimmer. All three light bulbs are adjustable, but none of the three bulbs can be dimmed to a brightness of 10%. By high-speed photography can see the flicker frequency of these three bulbs was higher than that of ordinary LED lighting, the flicker frequency is very high, generally cannot be visually noticed, but some people are more sensitive to flicker frequency, so it is also worth noting.

Through the above test, the results of the three models can be regarded as qualified high light bulb, but it is not recommended. All three lights
